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 Common problems found with poor forensic reports include extreme brevity, an inadequate data base, use of outdated or irrelevant tests, substantial errors in test scoring or interpretation, and failure to grasp the relevant legal constructs.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

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.

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.
