Backlash growing against criminal profiling

UK Guardian: "Psychological profiling 'worse than useless' "

In the beginning, there was Malcolm Gladwell's 2007 masterpiece in the New Yorker, exposing criminal profiling as clever sleight of hand. Three years later, reports in both New Scientist and the Guardian of UK are expressing mounting concerns over the pseudoscientific technique made bigger than life in fictional TV shows.

Leading the backlash is psychology professor Craig Jackson of the Centre for Applied Criminology at Birmingham City University. He will critique the scientific validity of profiling at the British Science Festival this week. Not only is profiling unscientific, say Jackson and a growing chorus of others, but it risks bringing the field of psychology into disrepute. As Ian Sample reports in today's Guardian:
In many cases, offender profiles are so vague as to be meaningless, according to psychologist Craig Jackson. At best, they have little impact on murder investigations; at worst they risk misleading investigators and waste police time, he said.

"Behavioural profiling has never led to the direct apprehension of a serial killer, a murderer, or a spree killer, so it seems to have no real-world value," Jackson said.
Despite profiling's lack of demonstrated validity, police forces around the world bring in behavioral experts in complex or high-profile cases, often to appease victims' families or the media. In the UK, for example, The Home Office keeps a register of experts who are qualified to render offender profiles based on crime information, the Guardian reports.
"It is given too much credibility as a scientific discipline. This is a serious issue that psychologists and behavioural scientists need to address," [Jackson] said. "People believe psychologists like 'Cracker' can exist." In the 1990s television series, police apprehended criminals with help from an overweight, chain-smoking alcoholic psychologist.

Jackson quoted one behavioural scientist as saying he "climbs inside the minds of monsters" and "takes the expression frozen on the face of a murder victim and works backwards."

"They bring themselves forward as if they are shamans who are cursed by nightmares and picturing dead people," Jackson said.
Jackson argues that, since people from marginalized groups are the primary victims of murder, "if we really want to deliver on the objective of reducing the numbers of people who fall victim to violent crime, then we would be just as well concentrating on eradicating homophobia, prejudice against sex workers and the elderly, rather than 'delving' into the heads of serial killers."

In an interview published today in the London Evening-Standard, the vice-chair of the British Psychological Society's forensic psychology division distanced forensic psychologists from criminal profiling. Carol Ireland said forensic psychologists worked in a wide range of areas, including offender risk assessments and interventions, helping victims, and conducting research.

A critical report by Jackson and two colleagues, "Against the Medical-Psychological Tradition of Understanding Serial Killing by Studying the Killers," is slated for publication next month in the legal journal Amicus Curiae, published by the Institute of Advanced Legal Studies at the University of London.

Paradoxical finding on juvenile sex offender risk

Leading tools cannot distinguish among delinquent boys

New tools designed to predict sex offender recidivism risk among juveniles continue to generate controversy and confusion. Some studies find that they work a bit better than the flip of a coin, and some find that they don't. Now, a new study out of Canada adds a paradoxical twist to the mix.

On two leading instruments, generally delinquent juveniles with a prior sex offense scored higher in risk than juveniles who had committed only sex offenses. And, true to this prediction, about 13 percent of these delinquent boys went on to commit another sex offense during the 6.6-year followup period, compared with just 7 percent of the boys with only sex offenses.

But, while they did moderately well at predicting risk among the non-delinquent juveniles, neither tool could reliably predict which among the delinquent, higher-risk youngsters would go on to reoffend sexually. The two instruments were the Juvenile Sex Offender Assessment Protocol-II (J-SOAP-II) and the Estimate of Risk of Adolescent Sexual Offense Recidivism (ERASOR).

A number of factors contribute to the difficulties in accurately predicting risk, especially among juveniles. These include:
  • Adolescent immaturity -- most juvenile offending is time-limited, and will spontaneously cease over time.
  • Low base rates -- it is hard to accurately predict events that have a low likelihood of occurring. In the current study, for example, only 9.4 percent of the youths were charged with another sex offense during the followup period.
  • Situational and random influences -- A lot of offending, especially among juveniles, is due to situational and environmental factors rather than personality variables, and these are extraordinarily hard to predict. (See this PSYBLOG post for a social psychology experiment demonstrating the underappreciated influence of situational variables.)
It all gets back to the larger problem I discussed in last week's report on the British metaanalysis of violence risk prediction tools: Maybe we will never find the Holy Grail. Maybe we've reached the summit of the mountain, and it’s time to step back.

The new study, by Gordana Rajlic and Heather M. Gretton of the Youth Forensic Psychiatric Services in Burnaby, British Columbia, is "An Examination of Two Sexual Recidivism Risk Measures in Adolescent Offenders: The Moderating Effect of Offender Type." It was published in the latest issue of Criminal Justice and Behavior and is available for free from Sage Publications for a limited time.

Mentally challenged Virginia woman facing death

While all eyes are on Iran's (just suspended) threat to stone a woman to death, a mentally challenged woman in the U.S. state of Virginia faces a more obscure death this month at the hands of her government.

The case of Teresa Lewis is one of dozens of skirmishes in U.S. death penalty states spawned by the Supreme Court's 2002 decision outlawing capital punishment for the mentally retarded. In the years since the Atkins ruling, an estimated 7 percent of condemned prisoners have filed claims on the basis of mental retardation, with about 40 percent succeeding in getting their death sentences overturned.

Central to these battles are opposing experts in forensic psychology. Their role illustrates the fundamental problem with science in court. The law asks a simple, black-and-white question: Is this person's IQ above or below the magic threshold for mental retardation (typically, an IQ score of 70)? Lewis scored 73 and 70 on IQ tests administered since her trial. Such minimal score differences are within the range of random fluctuations and are practically meaningless in a clinical context. But in the legal context, they can be the difference between life and death.

Psychology, in contrast to the law, sees nuances and shades of gray. An IQ score is only one data point, and must be combined with other relevant information to give a meaningful picture of a person's functional capacities. Here, a central issue is Lewis's personality style.

Lewis was sentenced to die under the theory that she masterminded the killing of her husband and stepson for a $350,000 life insurance policy. Although both triggermen received life sentences, Judge Charles Strauss gave Lewis the death penalty, reasoning that she was "clearly the head of this serpent," according to an account in yesterday's Huffington Post.

But new evidence suggests Lewis may have been manipulated into the crime. In a letter written before he killed himself in prison, gunman Matthew Shallenberger said the crime was entirely his idea, and he deliberately manipulated Lewis because he needed money and she "was an easy target."

Three forensic psychology experts have diagnosed Lewis with a dependent personality disorder. She is reportedly so dependent on others that she cannot make even simple decisions such as what to buy at the grocery store. Lewis's chaplain at Fluvanna Correctional Center for Women similarly described Lewis in a Newsweek essay appealing for clemency as "slow and overly eager to please -- an easy mark, in other words, for a con."

The state Supreme Court, a U.S. District Court, and, most recently, a U.S. Court of Appeals, have all upheld the death sentence. The execution, which will be Virginia's first killing of a woman in almost a century, is set for Sept. 23. She gets to choose between the electric chair or lethal injection.

Perhaps she should choose the latter; Kentucky, Oklahoma, and some other states may have to delay executions due to a shortage of one of the drugs in their lethal cocktails.

Metaanalysis debunks psychopathy-violence link

No clear winner among violence risk tools

If you are looking for the best tool to assess someone's risk for violence, the array may seem confusing. Lots of acronyms, lots of statistical data about AUC's (Areas Under the Curve) and the like. What do do?

No worries. As it turns out, they're pretty much interchangeable. That is the bottom-line finding of a groundbreaking metaanalytic study in the APA journal Psychological Bulletin by three academic researchers from the United Kingdom.

The University of Nottingham researchers used sophisticated statistical tools to meta-analyze multiple studies on the accuracy of nine leading violence risk assessment tools. All nine turned out to have similarly moderate predictive accuracy, with none clearly leading the pack. And none -- the scholars warned -- were sufficiently accurate for courts to rely upon them as a primary basis for decision-making in forensic cases requiring "a high level of predictive accuracy, such as preventive detention."

Widely touted PCL-R's "Factor 1" a bust

In a result with potentially momentous implications for forensic practitioners, the researchers found that Factor 1 of the Psychopathy Checklist-Revised (PCL-R) does not predict violence. As you know, Factor 1 purports to measure the core constellation of a psychopathic personality (superficial charm, manipulativeness, lack of empathy, etc.). When introduced in court, evidence of psychopathy has an enormously prejudicial impact on criminal offenders.

But, the PCL-R's much-ballyhooed ability to predict certain types of violence owes only to the instrument's second factor, according to the metaanalysis by researchers Min Yang, Steve Wong, and Jeremy Coid. And that's no surprise. After all, Factor 2 measures the criminogenic factors (criminality, irresponsibility, impulsivity, history of delinquency, etc.) that even a fifth-grader knows are bad signs for a future of law-abiding citizenship.

In my experience, the Factor 1 items -- the ones purporting to measure an underlying personality profile -- are the ones more likely to be inflated by some evaluators. That's because many of these items are pretty subjective. Glib? Superficially charming? If you don't like a guy -- and/or he doesn't like you -- you are more likely to rate these negative items as present. That's one of my hypotheses for the large evaluator differences and partisan allegiance effects found with the PCL-R in forensic practice.

Cumulatively, the emerging PCL-R findings beg the question:

Why introduce the Psychopathy Checklist in court if other violence risk tools work just as well, without the implicitly prejudicial effect of labeling someone as a "psychopath"?

Psychopathy evidence skyrocketing in juvenile cases

Despite (or perhaps because of, in some cases) its prejudicial impact, the construct of psychopathy is increasingly being introduced in court cases involving juveniles. It is often used to infer that a youth should get a longer sentence because he or she is dangerous and not amenable to treatment.

Skyrocketing use of psychopathy evidence in juvenile cases
Source: Viljoen et al, Psychology, Public Policy, and Law (2010)


The first systematic review, published in the current issue of Psychology, Public Policy, and Law, found the use of psychopathy evidence against juveniles skyrocketing in both Canada and the United States. Psychopathy evidence is typically introduced when juveniles are being sentenced as adults and in sex offender commitment cases. It is also introduced in a variety of other cases, including ones involving disputed confessions, competency to stand trial, and criminal responsibility, report authors Jodi Viljoen, Emily MacDougall, Nathalie Gagnon, and Kevin Douglas.

In one egregious case showing how judges may improperly use evidence of psychopathy, a Canadian judge reasoned that a youth's "psychopathic device [sic] score" showed that under his "shy and unassuming" exterior lurked "a monster" that "at any time ... may well come alive." As a result, the judge sentenced this minor to an adult penitentiary.

Such inferences of unremitting danger and untreatability are improper. A large proportion of youths measured high in psychopathy score lower on psychopathy instruments once they mature. And so-called psychopathic youths are far from untreatable; in one recent study by Michael Caldwell and colleagues, after intensive treatment youths who scored high in psychopathy were actually less likely to recidivate than a comparison group in a juvenile jail.

"[T]he introduction of psychopathy evidence into juvenile forensic contexts has been somewhat rushed and premature at times," the authors conclude.

Have risk prediction tools hit the ceiling?

Researchers have been toiling for almost five decades to perfect risk prediction tools. Unfortunately, they keep running into an insurmountable obstacle: A large proportion of violence is situational. It's affected by environmental context, not just qualities internal to the individual. And not only that, but it is always extremely hard to predict a rare event.

Based on their metaanalytic findings, the UK researchers say maybe it's time to stop searching for the holy grail. Maybe we've reached the ceiling of predictive efficacy.
Violent behavior is the result of the individual interacting with the immediate environment. Although it may be possible to improve on our understanding and predicting what an individual may do in hypothetical situations, it will be much more difficult to predict the situation that an individual actually encounters in the open community. Even predicting violence within an institutional environment is difficult, where the assessor has much more information about that environment.
Instead, they say, it is time to turn our attentions to interventions that can reduce risk:
Building a better model of violence prediction should not be the sole aim of risk prediction research, which is just one link in the risk assessment-prediction-management triad that aims to achieve violence reduction and improved mental health…The risk, need and responsivity principles derived from the theory of the psychology of criminal conduct provide a useful theoretical framework for risk reduction intervention. Appropriate risk assessment can identify high-risk individuals in need of more intensive management and intervention…. Using tools with dynamic risk predictors to assess risk can identify appropriate changeable treatment targets linked to violence.
The studies included in the metaanalysis were from six countries: the United Kingdom (11), Canada (9), Sweden (3), the United States (3), Holland (2), and Germany (1). The instruments included the PCL-R, the PCL:SV, the HCR-20, the VRAG, the OGRS, the RM2000V, the LSI/LSI-R, the GSIR, and the VRS, as well as seven instrument ubscales: PCL-R Factor 1 and Factor 2, the 10-item Historical subscale, the five-item Clinical subscale, and the five-item Risk Management subscale of the HCR-20; and the Static and Dynamic scales of the VRS.

Dr. Wong, former Research Director at the Regional Psychiatric Centre in Saskatoon, Saskatchewan, studied psychopathy and high-risk offenders for 25 years and developed the Violent Risk Scale and the Violence Risk Scale-sexual offender version before becoming a special professor at the Institute of Mental Health at the University of Nottingham. Dr. Yang is a professor of medical statistics with the Faculty of Medicine and Health Sciences at the University of Nottingham. And Dr. Coid, Director of the Forensic Psychiatry Research Unit, is principal investigator of the UK Home Office’s Prisoner Cohort Study and also studies the epidemiology of violent and criminal behavior at the population level.

Forensic psychology at the crossroads

Leading forensic psychologist calls for reform

Alas, summer is over. For my fall forensic overview course, I just read Kirk Heilbrun's new article in Psychology, Public Policy, and Law on the future of forensic psychology. He frames it in the context of the National Science Foundation's scathing report on problems with scientific accuracy and bias in other forensic science disciplines.

Psychology's progress in the forensic arena is at least as good as those of the hard sciences such as chemistry and biology, say Heilbrun and co-author Stephanie Brooks, also of Drexel University. The field has come a long way in the last three decades: Texts and journals galore, about three dozen forensically oriented doctoral programs, many doctoral internship sites with a significant forensic component, various sets of practice guidelines, and even a "best practices" series by Oxford University Press.

But we could do better, says Heilbrun, a pillar of the forensic psychology community.

The limited research on field practices finds three levels of competence:
  • Best practice: Forensic psychologists practicing at the aspirational level expected from highly trained and experienced specialists
  • Appropriate practice: Forensic psychologists who practice in a manner consistent with relevant standards and guidelines set by the field
  • Poor practice: Forensic psychologists whose work is so deficient that it is inaccurate, irrelevant, and/or not helpful to the courts.
Unfortunately, as many of us can attest, there is plenty of this poor-quality work, which can not only harm the individuals in the legal system but also damage our field's reputation. Common problems found with poor forensic reports include extreme brevity, an inadequate data base, use of outdated or irrelevant tests, substantial errors in test scoring or interpretation, and failure to grasp the relevant legal constructs.

Recommendations for improvement


In making recommendations to improve forensic psychology practice, Heilbrun and Brooks focus on the areas identified by the National Science Foundation study (which did not include the fields of psychiatry or psychology). These include both the quality of the underlying science and the elements of bias and human error. They recommend exploring the possibility of adding forensic psychology within the proposed National Institute of Forensic Science as one method of improving quality control. Other recommendations:
  • Develop quantifiable measures of reliability and accuracy of forensic analyses.
  • Competitively fund peer-reviewed research on the scientific bases of validity of forensic methods.
  • Develop quality improvement procedures to ensure best practice and minimize error.
Striking lack of diversity

Finally, Heilbrun and Brooks make a strong plea for greater attention to our field's lack of ethnic and cultural diversity, lest forensic psychology become irrelevant by the mid-21st century:
One of the striking gaps in forensic psychology is between those who provide services and those who are assessed and treated, and about whom legal decisions are made, in consideration of these services. It is crucial that this gap be narrowed. The racial and ethnic composition of the United States is changing; by 2040, it is estimated that Latina/Latino citizens will be in the majority. The delivery of services, and the research on their effectiveness, by individuals with a high degree of specific cultural competence is likely to be promoted by increasing the number of forensically trained psychologists of African American, Asian American, Latina/Latino, American Indian, Alaska Native, Native Hawaiian, and multiracial backgrounds providing such services.

Addressing this goal will require actively encouraging, even recruiting, minority individuals as early as high school. Minority issues within APA are promoted in part through a multigroup council. One potentially effective strategy for the field of forensic psychology would involve closer collaboration with councils like this and with secondary schools and colleges that educate substantial proportions of minority students. The effectiveness of this diversity effort will have a major impact on the extent to which forensic psychology is perceived as providing services that are culturally competent and effective—and the extent to which it actually provides such services.

"Islamophobia" prompting rise in hate crimes?

Chinese animation video seen worldwide

You have heard the hoopla over banning a mosque near "Ground Zero" in New York City. And the buzz about the startling level of American ignorance over President Obama's religion (a Pew poll showed about one in five Americans think he is Muslim). Now, a Chinese animated news video links these macro stories with the stabbing of a New York cab driver, making the case for a rise in anti-Muslim violence in the USA. Michael Enright (pictured at right), a film student, allegedly stabbed the cabbie out of anti-Muslim bias. Enright's journals will undoubtedly be used in court as evidence of the biased motivation necessary for a hate crime conviction. Ironically, given his own actions, he allegedly wrote that Muslims were "filthy murderers without a conscience." For a glimpse at international opinion, this 90-second video clip from Next Media Animation in Taiwan is worth checking out:

Report: Sexual abuse rampant in U.S. prisons

I will never forget "Sean," a young man I treated in prison. When he first arrived after a minor theft conviction, the 19-year-old was assigned a cell with an older convict who saw him as fresh meat. When Sean reported being raped, he was moved to a segregation housing unit for safety. Solitary housing was like torture for this active young man. After months without stimulation, he tried to hang himself. He was punished by being transferred to a harsher prison.

Sean came to mind when I saw the report released today from the Bureau of Justice Statistics (BJS) reporting epidemic levels of sexual abuse of prisoners across the United States. At least 88,500 prison and jail inmates were abused last year, many repeatedly. Several facts in the report, mandatory under the Prison Rape Elimination Act of 2003, are worth highlighting:
  • Guards commit much of the abuse
  • Women prisoners are more at risk from other prisoners, while men are most at risk from guards
  • Gay, transgender, and effeminate prisoners are at heightened risk, as are prisoners with histories of sexual abuse
  • Much of the abuse happens on the first day

The news comes as no surprise to the folks at Just Detention International, an organization dedicated to ending sexual abuse behind bars. They receive dozens of letters a week from prisoners who are being sexually abused.
  • William in Texas wrote that he would misbehave to get locked in the hole just to get away from the guard who was sexually abusing him. He has tried to kill himself, and fears telling his longtime girlfriend.
  • James, a gay prisoner in Michigan, has been raped more than 20 times by numerous prisoners. "Do you know what it's like to see their faces each day? Seeing the look they give me? Knowing that they smile and laugh,” he wrote.
A call for research and action by psychology

Just ahead of the report's release, two psychologists published an article in Psychology, Public Policy, and Law calling for more attention to the problem. "To date, psychology has been largely silent on the issue of prison rape," wrote Tess Neal and Carl Clements of the University of Alabama.

In their article, "Prison Rape and Psychological Sequelae: A Call for Research," Neal and Clements call for research into the "rape subculture" that makes sexual victimization more prevalent in American prisons than elsewhere in the world:
It appears that prison rape in the United States is a much more serious problem than it is in other countries. This fact calls for comparative analysis of systems to look for correlates of victimization rates. What is it about the U.S. prison system that exacerbates the problem of prison rape? Some would argue that inordinately high incarceration rates, and policies that capture more persons with mental disorders is part of the systemic problem. Can these conditions be reversed?
They go on to discuss the "serious and long-lasting" effects of prison rape, "with potentially devastating physiological, social, and psychological components":
Many rapes are violent, bloody, and physically traumatic to victims. Gang rapes are often characterized by extreme abuse and may be particularly traumatic. In addition, the threat and reality of contracting HIV/AIDS has added a new dimension of physical and psychological terror for victims. Loss of social status in the prison facility, labeling, stigmatization, and further victimization are other potential consequences for victims…. The postrape symptoms of prison rape survivors may be even more complex and pervasive than those of other types of sexual assaults based on the fact that many victims are repeatedly assaulted, experience negative social reactions from the prison community, including many staff, and may be perceived as homosexual. The humiliation and perceived loss of one's masculinity, as well as the extensive victim blaming found in prisons could perpetuate the negative psychological effects, possibly increasing the risk of developing PTSD.
The role of expert witnesses

Under the 1994 U.S. Supreme Court case of Farmer v. Brennan, prison administrations are liable when they practice "deliberate indifference" to prison rape. Neal and Clements discuss how expert psychological testimony may be useful in such civil litigation, the authors explain, both to explain the psychological sequelae experienced by prisoners and to discuss the environments that foster prison rape. Further research is also needed into the legal atmosphere surrounding such litigation, they note:
Courtroom dynamics in these atypical cases (e.g., when a male prison rape survivor is a plaintiff filing suit against prison officials) need to be examined. Public biases should be identified so that they can be countered with informative testimony to dispel them. Investigations using the diagnosis of PTSD in these circumstances should be initiated to learn more about how jurors respond to the traumatic aspects of prison rape victimization. As research uncovers more accurate descriptions of the psychological sequelae of such victimization, researchers should examine how jurors respond to these new descriptions in a courtroom setting
The full report by BJS statisticians Allen J. Beck and Paige M Harrison is HERE; selected highlights and a press release are HERE. Correspondence concerning the Psychology, Public Policy, and Law should go to Tess Neal of the University of Alabama.

Forensic update: Malingering and incompetency

New response style measure hitting the market

Randy Otto and colleagues are as busy as beavers these days. I just blogged about Dr. Otto's new violence risk assessment text; now he and colleagues Jeffrey Musick and Christina Sherrod are releasing the Inventory of Legal Knowledge, a brief measure of response style for defendants undergoing adjudicative competence evaluations.

The 61-item, true-false test is orally administered and takes about 15 minutes. Questions are phrased in simple language and concern the legal process. It's highly portable for in-custody settings. And at $129 for the complete kit it's not a bad deal, considering PAR's normally hefty pricing. (You can order it now, but it won't actually release until mid-September.)

The theoretical basis is the same as for the Test of Memory Malingering and other measures of malingering; one suspects dissimulation when scores are either significantly lower than chance or significantly lower than attained by relevant normative groups.

A validation study has been published online in advance of the print edition of Assessment. The study, by the test authors, is titled: “Convergent validity of a screening measure designed to identify defendants feigning knowledge deficits related to competence to stand trial.” Here is the Abstract:
Because some defendants undergoing evaluation of their competence to stand trial may feign limitations in their ability to understand and participate in the legal process, assessment of their response style is critical. Preliminary research indicates that the Inventory of Legal Knowledge (ILK) has some potential to identify persons feigning competence related impairments. This study examined the convergent validity of the ILK using a sample of criminal defendants who, while undergoing competency evaluations, were administered the ILK and other response style measures. Moderate correlations between the ILK and these other tools provided some support for the ILK as a measure of response style.
More information is HERE.

Online review of updated SIRS malingering test

Richard Rogers' widely utilized Structured Inventory of Reported Symptoms (SIRS) has just been updated with a second edition, and forensic psychologist Steve Rubenzer of Houston, Texas (where "we don't only sing, but we dance just as good as we walk") has a critical review in the Open Access Journal of Forensic Psychology. The abstract:
The Structured Inventory of Reported Symptoms-2 (SIRS-2) contains significant changes designed to prevent false-positive and false-negative classification errors. While the SIRS-2 has many laudatory features, the manual contains some erroneous and questionable statistics and arguments, and authors sometimes stray from the best practices advocated by the first author. The SIRS-2 is a strong choice for assessing feigned psychosis and severe psychopathology. However, evidence for its value in assessing many other conditions, particularly somatic complaints and feigned cognitive impairment, is quite limited.
The full review is online HERE.

Overview: Feigning adjudicative incompetence

And, there's more! Sherif Soliman and Phillip J. Resnick have an overview of accepted methods for detecting feigning in competency evaluations, including specific instruments and their limitations, forthcoming from in an upcoming issue of Behavioral Sciences & the Law that is now online in advance of the print edition. The abstract:
Competence to stand trial (adjudicative competence) is the most requested forensic psychiatric evaluation, with an estimated 60,000 referrals annually. The challenge of detecting feigned incompetence has not been systematically studied until the past decade. Estimates of feigned adjudicative incompetence vary from 8 to 21%. This article reviews techniques for detecting malingered psychosis and malingered cognitive impairment during competence evaluations. Specific techniques for assessing feigned adjudicative incompetence and estimating the malingerer's genuine abilities are discussed. A stepwise approach to suspected feigned adjudicative incompetence is proffered.
Since this manuscript was already in press when the new ILK and the revised SIRS-2 were released, these instruments are not reviewed. In addition to a basic overview of instruments, however, Soliman and Resnick also describe a structured approach. As the authors point out, "Unlike many other evaluations, the assessment of adjudicative competence does not end with the determination that the defendant is malingering." Even with an uncooperative individual, the evaluator must make an effort to determine the subject's genuine capabilities.

Correspondence about that article should go to Dr. Soliman, Senior Clinical Instructor of Psychiatry at Case Western Reserve University in Ohio.

Handbook of Violence Risk Assessment

Best practices for violence risk assessment change from second to second. So, publishing a sourcebook on the topic is a bit like trying to capture and hold a hummingbird. Still, the authorship and range of content may make the Handbook of Violence Risk Assessment an authoritative resource for at least a minute or two -- and then they can publish a second edition.

The volume's first editor, Randy Otto, is a respected forensic psychology scholar. An award-winning professor in the Department of Mental Health Law and Policy at the University of South Florida, he is past president of both the American Psychology-Law Society and the American Board of Forensic Psychology. He also chairs the Committee to Revise the Specialty Guidelines for Forensic Psychology (which, by the way, has yet a new draft coming out next month), and he is a co-author of the third edition of the widely consulted text, Psychological Evaluations for the Courts. Co-editor Kevin Douglas is a former colleague of Otto's at the Department of Mental Health Law and Policy.

The book begins with an overview chapter by respected forensic scholar Kirk Heilbrun. Remaining chapters -- most written by leading practitioners and instrument developers -- review specific instruments for assessing both adult and juvenile risk for violence, including sexual violence. Tools reviewed include:
  • EARL-20B and EARL-21G
  • SAVRY
  • Youth Level of Service/Case Management Inventory
  • VRAG, SORAG
  • Violence Risk Scale
  • HCR-20
  • Classification of Violence Risk
  • Level of Service Inventory
  • Spousal Assault Risk Assessment Guide
  • Static-99
  • SVR-20 / RSVP
I am impressed with what I have read so far. John Monahan wrote the chapter on the Classification of Violence Risk. David DeMatteo, John Edens, and Allison Hart have a nice chapter on the utility -- and limitations -- of using psychopathy measures to address violence risk. And Stephen Hart and Douglas Boer provide an up-to-the-minute summary of reliability and validity studies on the SVR-20 and a parallel instrument sex offender risk instrument, the Risk for Sexual Violence Protocol (RSVP), which I predict may overtake the Static-99 at some point, given the latter's instability and atheoretical basis.

Blast from the past: "Sex offender myths"

Amidst all the hysteria over sex offending these days, stumbling across this list from 1955 gave me an eerie sense of deja vu. The author, a prominent sociologist, wrote his list of 11 "popular myths about the sex offender" during the zenith of the last sex panic, the Sexual Psychopath Era of the 1930s-1950s. Here are his myths*:

  1. That tens of thousands of homosexual sex offenders stalk the land.
  2. That the victims of sex attack are 'ruined for life.'
  3. That sex offenders are usually recidivists.
  4. That the minor sex offenders, if unchecked, progress to more serious types of crime.
  5. That it is possible to predict the danger of serious crimes by sexual deviance.
  6. That 'sex psychopathy' or sex deviation is a clinical entity.
  7. That these individuals are lustful and oversexed.
  8. That reasonably effective treatment methods to cure deviant sex offenders are known and employed.
  9. That the sex control laws passed recently are getting at the brutal and vicious sex criminal and should be adopted generally to wipe out sex crime.
  10. That civil adjudication of the sexual deviant in indeterminate commitment to a mental hospital is similar to our handling of the insane and therefore human liberties and due process are not involved.
  11. That the sex problem can be solved merely by passing a new law on it.
As a wise poet and philosopher wrote way back when, "Those who cannot remember the past are condemned to repeat it." Kind of depressing that many in the sex offender civil commitment industry seem oblivious to 20th century history, in which an almost identical approach was vigorously pursued, only to be abandoned as an abysmal failure.

APA Dispatch II: Whither juvenile forensics?

The U.S. Supreme Court ruling this May in Graham v. Florida, restricting life without parole sentences for juveniles, relied in part upon scientific evidence from developmental psychology and neuroscience. In ruling that juveniles are categorically different from adults, the high court was assisted by amicus briefs from the American Psychological Association and other professional organizations including the American Psychiatric Association and the National Association of Social Workers.

The APA's position, which the Supreme Court also validated in its 2005 ruling in Roper v. Simmons outlawing the death penalty for juveniles, is that juveniles' diminished culpability is based on three basic differences from adults:
  1. Immaturity: Juveniles are more impulsive and less likely to reason judiciously about risk
  2. Vulnerability: They are more likely to be influenced by peer pressure
  3. Changeability: They are still developing, and are more amenable to rehabilitation than adults
At this week's APA convention, the American Psychology-Law Society (Division 41) hosted a cutting-edge track on juvenile justice. The dynamic sessions raised intriguing issues about how the growing acceptance of adolescent immaturity and difference will affect forensic practice in the juvenile justice system.

Bryan Stevenson: "Huge implications" of Graham case

In an eloquent presentation, NYU law professor Bryan A. Stevenson, founder of Alabama's Equal Justice Initiative, expressed optimism that Graham and the twin case of Sullivan v. Florida, in which he was counsel, signal that the tide is turning away from the punitive Superpredator hysteria of the 1980s. He encouraged the APA to continue its public policy advocacy by bringing legal attention to the impacts of trauma, violence, and neglect on youngsters.

Hopefully, the capacity crowd of psychologists will attend to the implications of Stevenson’s other take-home messages: Mass incarceration has radically changed American society, creating a class of "new untouchables." And the victims of this sea change are overwhelmingly poor and minority. Indeed, he asserted, wealth -- not criminal culpability -- largely drives criminal sentencing. In Louisiana, for example, of the juveniles serving life without parole for crimes other than homicide at the time of the Graham decision, 94 percent are African American. Most are incarcerated for rape, with 71 percent of the victims being white.

Tom Grisso: "Forensic examiners beware"

Forensic psychology guru Tom Grisso sounded a more cautionary note about Graham's implications. The high court's adoption of a categorical approach to juveniles is at odds with the discretionary, individualized method at the core of forensic assessment, he pointed out.

Grisso demonstrated his point through a mock cross-examination. On the stand, the mock expert conceded that the research of Laurence Steinberg, Elizabeth Cauffman, and others on adolescent immaturity is now widely accepted in the field, as shown by Supreme Court's rulings in Graham and Roper. Next, Grisso produced a New York Times op-ed co-authored by Steinberg, reiterating Roper's conclusion that psychologists "are unable to distinguish between the young person whose crime reflects transient immaturity and the rare juvenile offender who may deserve the harsh sentence of life without parole." In the script, the expert was left speechless and incapable of defending her individualized opinions about risk.

Grisso said forensic psychologists must be aware of this debate, and think about how to answer such questions in court. The outlook for prediction is not as bleak as the APA's advocacy efforts might suggest, he asserted, as experts do have a reliable basis on which to give probability estimates, especially about more short-term risk.

Good news for juveniles with a sex crime

A panel of juvenile sex offender experts was more upbeat about the implications of the scientific research on adolescent difference. As with general criminality, they said, research has not identified methods to accurately predict which juveniles will reoffend sexually. Indeed, none of the factors that predict sex offender recidivism in adults (multiple victims, male victims, young child victims, personality disorder, sexual deviance, etc.) predict recidivism for juveniles.

But this inability to differentiate is not bad news, because what we can say is that the overwhelming majority -- 93 percent -- of juveniles who have committed a sex crime will not reoffend sexually as adults.

An audience member who works in the civil commitment industry expressed incredulity at the cumulative research, saying many of the men in his civil detention facility began their offending careers in their teens.

That may be true, responded researcher Michael Caldwell. But the directionality cannot be reversed. All NBA stars may have played basketball in the ninth grade. But we cannot predict by watching a group of ninth-graders play basketball which, if any, of the players will become basketball superstars.

Judges launch crusade to save children of color

The most optimistic presentation I attended was a symposium of family court judges who are at the forefront of a movement to reduce the vastly disproportionate representation of minority children in the child welfare system, from which many graduate to juvenile delinquency and adult criminal courts.

The remarkable Hon. Katherine Lucero of San Jose, California said she became active in this movement when she realized she was serving as part of the vast "cradle-to-prison pipeline," processing children who would end up poor, homeless, drug addicted, illiterate, pregnant at a young age, delinquent, and -- ultimately -- incarcerated. When she looked out at her courtroom filled with children of color, her training that justice is blind was cognitively dissonant, making her feel like she was living "in a delusion."

The equally inspiring Hon. Nan Waller of Portland, Oregon said the movement challenges the basic historical tenet of the child welfare system, which promotes removal from families -- so-called "child rescue" -- rather than family strengthening. Most of the mothers who lose their children are suffering from severe trauma that they medicate with drugs. Rather than "cookie-cutter" quick-fixes, including automatic referrals for psychological evaluations and parenting classes, these women need support and help obtaining even basic resources such as housing, transportation, and health care, the judges said.

Assisted by a research and advocacy project of the National Council on Juvenile and Family Court Judges, these and other judges are using a combination of model courts, wraparound services, community interventions, training in implicit race bias at all levels of the system, and other creative methods to reduce the number of children who are placed in foster care. Already, their data show they are having an impact in their respective communities.

Alarming call for preventive detention of children

In the discussion period following their presentation, the judges said they are turning away from ordering psychological reports except when a parent has a genuine, severe mental disorder. They gave two reasons for this. First, psychological evaluations are costly. Second, and more important, the judges do not find it helpful to "slap" pathologizing psychiatric labels on parents. They expressed curiosity as to whether and how we in the field of psychology are working to address the effects of poverty and racism in the populations we serve.

Sadly, the honest answer is that many forensic practitioners and scholars are not adequately addressing the impact of larger social forces -- poverty, race, trauma -- on the people we evaluate, treat, and/or study. Perhaps the sparse attendance at the judges' presentation as compared with other seminars in the forensic juvenile justice track is an indicator of this neglect.

Indeed, at a more well-attended session came a chilling proposal at the polar opposite extreme: To establish a system to preventively detain dangerous juveniles. Raising this "public safety" proposal was attorney Christopher Slobogin, a co-author of the forensic psychology stalwart Psychological Evaluations for the Courts. It will formally air in a book, Juveniles at Risk: A Plea for Preventive Justice, forthcoming from Oxford University Press. Slobogin has good intentions, I am sure; he believes such a model will treat juveniles more fairly and help stem the erosion of the separate juvenile justice system.

But the proposal has potentially far-reaching unintended consequences. It myopically ignores what the family court judges and attorney Stevenson are so painfully aware of: The differential treatment of poor and minority children. It is hard to accurately predict juvenile risk, and actuarial risk prediction tools are especially inaccurate when applied to juveniles. This is just the type of nebulous decision-making situation in which implicit (unconscious) biases are most salient, research shows. Forensic psychological evaluations would provide a scientific veneer, masking racial and class biases in deciding who is labeled as dangerous and who is not.

Rather than locking up kids for crimes they have not (yet) committed, we should be working to give young victims of trauma and abuse -- and their families -- the practical resources and tools they need to lead productive lives. Let's hope the field of psychology and public policymakers heed the pleas of the judges and attorneys in the trenches who are fighting to save kids before they get sucked into the "cradle-to-prison pipeline" in the first place.

APA Dispatch I: Science and public policy

I had intended to limit my dispatches from the American Psychological Association convention in San Diego to forensic highlights. But I would be remiss if I didn't touch on the big news from psychological science and public policy. Anyway, it's all related to forensics.

Conference theme: Ending marriage discrimination

A public policy highlight of the convention was its theme of opposing marriage laws that discriminate against gay men and lesbians. Walking into the futuristic convention hall, one was greeted by a life-sized hologram of the APA's CEO, Norman B. Anderson, speaking of the scientific advocacy role in this area of the APA, which at 152,000 members is the world's largest psychological organization and devotes a good share of its $115 million annual budget to advocacy. Kiosks gave attendees a chance to don large lapel pins supporting marriage equality, or send a message to their legislator calling for an end to the federal ban on same-sex marriage.

The theme, planned months ago, could not have been more timely, especially given the conference's location. Just as the convention got underway yesterday, Judge Vaughan Walker lifted the stay on gay marriages in California following his earlier ruling that marriage discrimination was unconstitutional. Many of the key expert witnesses who presented scientific evidence at that trial were featured speakers at the convention: Gregory Herek of UC Davis on sexual orientation and stigma (introduced by APA President Carol Goodheart), Anne Peplau of UCLA on same-sex relationships, and Charlotte Patterson of the University of Virginia summarizing the empirical research regarding the emotional health of children raised in lesbian and gay families.

The APA leadership seems delighted to be on the correct side of history this time, especially after the lengthy debacle over psychologists' role in the torture of detainees at Guantanamo.

Memory: How the brain reconstructs reality

Meanwhile, memory research was on the cutting edge of the psychological science presented at the convention. I had the great fortune to hear preeminent scholar Daniel Schacter present some of the very latest findings.

We already know that retrieving a memory is nothing like opening a file on your computer. In calling up a memory, the brain -- specifically the hippocampus -- grabs a bunch of bits and pieces stored here and there around the brain, and reintegrates them to suit the current situational demand. This is adaptive. It allows us to use our accumulated experience to respond flexibly to an ever-changing environment. But it comes at a cost of errors and distortions, which Schacter has summarized beautifully in The Seven Sins of Memory (which all forensic practitioners should read).

In his talk, Schacter illustrated with the case of "John Doe 2," the composite creation of a faulty memory who was the subject of a massive FBI manhunt after the Oklahoma City bombing. As it turned out, John Doe 2 (despite lingering conspiracy theories to the controversy) was most probably an Army private who had nothing whatsoever to do with McVeigh; he happened to have been at the auto body shop where McVeigh rented his van, but a full day later.

The advent of neuroimaging technology has enabled this memory research to advance at a rapid pace. (The hippocampus even has its own journal now, named after itself!) In their most recent work, Schacter and his colleagues are localizing the precise hippocampal sites that activate when various tasks are being performed. Distinct patterns of hippocampal activity are visible on fMRI when someone is storing initial memories, retrieving those memories, and imagining future possibilities.

Intriguingly, it turns out that the brain tasks involved in remembering are not so different from those involved in imagining the future, or imagining a fictional version of the past, for that matter. Which makes sense: Like recalling real events, imagining fictional scenarios first requires us to think about our past experiences, and then tweak them (consciously or unconsciously).

Australian study: Sharing distorts eyewitness memory

The fact that the very act of retrieving a memory causes it to be distorted (also the topic of a rather dry convention presentation by researcher Joseph LeDoux, author of The Emotional Brain) explains a new finding by forensic psychology lecturer Helen Paterson of the University of Sydney in Australia. She found that sharing memories leads to contamination that cannot be reversed through providing corrective information.

Paterson's team showed participants one of two different versions of a video of a crime. After discussing the crime with each other, most participants reported seeing specific details that were not in the version they had watched. The researchers believe that discussions among co-witnesses are more likely to damage accurate recall for a crime than are other avenues of distorted information such as reading a news account or being asked leading questions by investigators.

Like the broader memory research of Schacter and others, Paterson's study, published in the journal Applied Cognitive Psychology, has direct implications for witness reliability. Once a memory is distorted, the inaccuracies remain even when witnesses are told that the new information is wrong, as witnesses " find it difficult, if not impossible, to distinguish between genuine memories and false memories of an event," Paterson said.

The forensic implications of this line of memory research are rather mind-boggling, when you stop and think about it. Not only do we need to be extremely cautious about putting too much weight on someone's memory for an event but, as the accumulating research shows, we must be skeptical even if multiple people agree on the "facts."

Sexual sadism diagnosis not predictive

In another blow to the controverial sexual paraphilia diagnoses, a group of prominent researchers has found that the diagnosis of sexual sadism is not related to sex offender recidivism. Unlike some of the made-up paraphilias being used in court to justify civil commitment of sex offenders, sexual sadism is actually listed in the American Psychiatric Association's current Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), and it is planned for inclusion in the upcoming fifth edition as well.

The longitudinal study followed almost 600 convicted sex offenders for up to 20 years. The researchers found that a sexual sadism diagnosis did not predict any type of recidivism. This was in contrast to sexual arousal to violence as measured phallometrically, which was associated with future violence, including sexual violence.

The study replicates and extends what the authors call "accumulating evidence of specific problems with the reliability of paraphilia diagnoses, including sexual sadism."
[O]ur results raise questions about the clinical utility of the DSM diagnosis of sexual sadism. This appears to be a problem for other paraphilia diagnoses as well [including pedophilia].
The findings are relevant to the upcoming fifth edition of the DSM, the authors note, because the proposed criteria for sexual sadism are "very similar" to the criteria in current and previous editions.

The study, "Comparing indicators of sexual sadism as predictors of recidivism among adult male sexual offenders," by Drew Kingston, Michael Seto, Philip Firestone, and John Bradford, appears in the Journal of Consulting and Clinical Psychology.
