Evaluating vets for disability: Recommended reading

As thousands of U.S. vets stream back from the battlefields of the Middle East with physical and/or psychological problems, more and more forensic practitioners are being called into service to perform disability evaluations. Veterans who suffered illness or injury due to military service are eligible for disability compensation. But first, they must meet eligibility requirements, which typically include undergoing a disability evaluation (referred to as a "Compensation and Pension examination" or "C and P" in VA parlance).

Not surprisingly, the majority of psychiatric evaluations are for PTSD.

A group of psychologists and psychiatrists who conduct such evaluations has put together a reading list of recommended resources for evaluators. Although one obvious audience is the mental health staff of the Veteran's Administration, the group is also reaching out to clinicians in private practice who conduct mental disability evaluations with veterans, either directly for the veteran or via private companies who have contracts with the VA.

For questions about this reading list, please contact Mark D Worthen, PsyD, who has blogged here before and led the effort to compile the list. Dr. Worthen is also co-author of the only article published in a peer-reviewed journal that describes how to conduct mental disability evaluations with veterans.

Best of all, many of these resources are available online; just click on the embedded links.

Mental health expert witnesses slammed in court

A pint-sized hired gun
Are accusations of bias on the rise?

Hired gun.
Charlatan.
Quack.
Hack.

It's every expert witness's worst nightmare. Vitriolic accusations of bias hurled at us on the witness stand, just because the cross-examining attorney doesn't like our opinion, or we have the audacity to charge for our services. (Have you heard of auto mechanics, plumbers or attorneys being called "whores" because they don't work for free?)

Unfortunately, it goes with the territory.

Now, a group of psychologists has tried to figure out just how big a part of the legal landscape accusations of bias against mental health expert witnesses are. The researchers scoured the LexisNexis legal database for insinuations of bias, with an eye to quantifying and categorizing the name-calling. In an article just published online in the journal Psychological Services, prominent forensic psychologists John Edens and John Petrila and four colleagues divided accusations of bias into five major categories:
    Starting with a list of 46 different ways of calling an expert biased, the authors searched and found 160 legal cases in which attorneys and judges made disparaging comments about forensic mental health experts. In these cases, 185 individual case participants made a total of 245 separable statements asserting a lack of objectivity and impartiality among mental health experts and/or the fields of psychology and psychiatry more generally.
    • FOR SALE: In the largest category, 28 percent of the total, experts were disparaged as financially biased (e.g., "hired guns" or "prostitutes").

    • PARTISANSHIP: Following close behind, with 27 percent  of cases, were accusations of advocacy, or having an "axe to grind."

    • PSEUDOSCIENCE: About 14 percent of cases involved accusations of non-scientific testimony (e.g., "charlatans" or "junk science").

    • MYSTICISM: Psychologists and psychiatrists were accused of babbling nonsense (e.g., "witch doctor," "voodoo" or "hocus pocus") in 6 percent  of the cases.

    • NONSPECIFIC BIAS: About one fourth, or 24 percent, of cases involved nonspecific accusations or other types of allegations of bias. 
    Interestingly, in more than a fourth of the cases, the disparaging comments were a basis for an appeal, typically by the defense calling foul over prosecutorial slurs against mental health experts. Such appeals were relatively unsuccessful, with only 18 percent of cases being reversed in part due to on-the-record accusations of expert bias. All of the successful appeals were in criminal trials, eight involving sanity or diminished capacity. 

    Uptick in nasty name-calling?

    Similar to a 1999 study by Doug Mossman, which was the only other known study to look at this issue, the researchers noticed a steady upward trend in disparaging comments in more recent years.

    It might be tempting to get depressed by this study, which at first blush seems to validate what we all know and fear. However, if we think about it, the results could be seen as mildly encouraging.

    First of all, if a thorough search of the massive LexisNexis database could locate only 160 cases, then blatant accusations of bias may be rarer than we think.

    Secondly, there are a heck of a lot more expert witnesses in court these days than ever before. Courts and attorneys increasingly rely on forensic psychologists and psychiatrists to assist in a wide range of psycholegal areas, from child custody to tort damages to criminal sentencing and civil commitment. As well, we are increasingly called upon to explain broader social science research, such as the accuracy of eyewitness identification, to judges and juries. So, as the authors acknowledge, any increase in accusations of bias could just be an artifact of our growing presence in court.

    Third, and perhaps most importantly, there really are hacks and quacks, charlatans and hired guns among are ranks. The methodology of the current study did not enable analysis of whether the accusations of partiality or bias were legitimate. In other words, attorneys may not have been just engaging in legal gamesmanship in some of these cases; they might have been righteously upset over actual bias or pseudoscientific methodology on the part of forensic psychologists or psychiatrists.

    Hopefully, that's a study someone else will take up on another day.

    For now, we're left with a couple of take-home messages:

    First, this is not a field for the thin-skinned. We must steel themselves to have our objectivity challenged, sometimes very rudely and without basis.

    More fundamentally, assuming that these accusations are tapping into popular perceptions and prejudices, forensic professionals need to work harder to reduce both actual bias and the perception of bias in our work.

    Psychiatrist accused of faking dementia to thwart retrial

    Ayres found competent to stand trial in long-running molest case

    William Ayres
    In a dramatic twist to a case that's already had as many twists and turns as a roller coaster, allegations surfaced this week that psychiatrist William Ayres faked severe dementia in order to avoid a retrial on multiple charges of child molestation.

    Ayres used his knowledge of psychiatry to circumvent psychological testing in an elaborate, two-year hoax, according to a report by state hospital psychologist John McIlnay. Around-the-clock observation at Napa State Hospital uncovered discrepancies between the dementia diagnosis and the day-to-day conduct of the former president of the American Academy of Child and Adolescent Psychiatry, the psychologist reportedly wrote in a report filed under seal with the San Mateo County, California court.

    Ayres, 80, was arrested in 2007 on suspicion of sexually abusing six boys, some of them sent to him by the juvenile courts, between 1988 and 1996. As I reported at the time, his 2009 criminal trial ended with a hung jury.

    After that trial, a new lawyer took over the case and raised the issue of competency to stand trial. A jury trial on competency last year ended with another hung jury. The defense and the prosecution eventually stipulated that Ayres was incompetent and should be sent to Napa State Hospital. He was there for about nine months.

    Vincent "The Chin" Gigante
    Faking dementia is not commonplace or easy, but it can be done. The most famous case of a defendant faking dementia in order to avoid criminal trial was that of Vincent "The Chin" Gigante, a Mafia don who for years wandered the streets of New York City in a bathrobe. He fooled a bevy of eminent forensic psychologists for psychiatrists into believing he was both insane and demented.

    Due to his medical training, a psychiatrist would have an advantage in faking a dementia and in avoiding obvious mistakes. But never letting down one's guard would be difficult in an environment of 24/7 observation. According to news reports, line staff such as nurses and janitors were among those who noticed discrepancies between Ayres's day-to-day functioning and his purported dementia. This was also what eventually tripped up Vincente Gigante; forensic evaluators who interviewed line staff in that case learned that "The Chin" had dropped his guard in jail, when outside the presence of evaluating psychologists and psychiatrists.

    On the other hand, state hospital clinicians are rather notorious in local circles for being quick to label defendants as malingering, a topic on which I published a peer-reviewed case study a few years ago. The diagnosis helps open up space in the overcrowded competency restoration wards, which are under pressure from California judges to become more efficient and reduce long waiting periods for beds, and can rid staff of nettlesome criminal patients.

    Also, as regular blog readers know, reasonable clinicians often differ as to whether someone is incompetent. In this case, the competency trial featured a 2-2 split of experts. The two original court-appointed psychologists, Paul Good and Jatinder Singh, both initially opined that Ayres was competent to stand trial. However, Singh later changed his mind, which prompted the appointment of a third, "tie-breaker" evaluator, psychiatrist George L Wilkenson, who also thought Ayres was competent. Joining those three as witnesses at last year's competency trial was a defense-retained neuropsychologist, Amanda Gregory, who opined that Ayres was incompetent.

    The new hospital report will prompt yet another court hearing on competency. This time, a judge rather than a jury will make the decision on competency, with the defense having the burden of proving that the defendant is unfit for trial on nine felony child molestation charges. The October hearing will include a string of lay and expert witnesses and is anticipated to last about seven days.

    Violence risk instruments overpredicting danger

    Tools better at screening for low risk than pinpointing high risk 


    The team of Seena Fazel and Jay Singh are at it again, bringing us yet another gigantic review of studies on the accuracy of the most widely used instruments for assessing risk of violence and sexual recidivism.


    This time, the prolific researchers -- joined by UK statistician Helen Doll and Swedish professor Martin Grann -- report on a total of 73 research samples comprising 24,847 people from 13 countries. Cumulatively, the samples had a high base rate of reoffense, with almost one in four reoffending over an average of about four years.

    Bottom line: Risk assessment instruments are fairly good at identifying low risk individuals, but their high rates of false positives -- people falsely flagged as recidivists -- make them inappropriate “as sole determinants of detention, sentencing, and release.”

    In all, about four out of ten of those individuals judged to be at moderate to high risk of future violence went on to violently offend. Prediction of sexual reoffense was even poorer, with less than one out of four of those judged to be at moderate to high risk going on to sexually offend. In samples with lower base rates, the researchers pointed out, predictive accuracy will be even poorer.

    What that means, in practical terms, is that to stop one person who will go on to become violent again in the future, society must lock up at minimum one person who will NOT; for sex offenders, at least three non-recidivists must be detained for every recidivist. This, of course, is problematic from a human rights standpoint. 

    Another key finding that goes against conventional wisdom was that actuarial instruments that focus on historical risk factors perform no better than tools based on clinical judgment, a finding contrary to some previous review.

    The researchers included the nine most commonly used risk assessment tools, out of the many dozens that have now been developed around the world:
    • Level of Service Inventory-Revised (LSI-R) 
    • Psychopathy Checklist-Revised (PCL-R) 
    • Sex Offender Risk Appraisal Guide (SORAG) 
    • Static-99 
    • Violence Risk Appraisal Guide (VRAG) 
    • Historical, Clinical, Risk management-20 (HCR-20) 
    • Sexual Violence Risk-20 (SVR-20) 
    • Spousal Assault Risk Assessment (SARA) 
    • Structured Assessment of Violence Risk in Youth (SAVRY) 
    Team leader Fazel, of Oxford University, and colleagues stressed several key implications of their findings:
    One implication of these findings is that, even after 30 years of development, the view that violence, sexual, or criminal risk can be predicted in most cases is not evidence based. This message is important for the general public, media, and some administrations who may have unrealistic expectations of risk prediction for clinicians. 

    A second and related implication is that these tools are not sufficient on their own for the purposes of risk assessment. In some criminal justice systems, expert testimony commonly uses scores from these instruments in a simplistic way to estimate an individual’s risk of serious repeat offending. However, our review suggests that risk assessment tools in their current form can only be used to roughly classify individuals at the group level, and not to safely determine criminal prognosis in an individual case. 

    Finally, our review suggests that these instruments should be used differently. Since they had higher negative predictive values, one potential approach would be to use them to screen out low risk individuals. Researchers and policy makers could use the number safely discharged to determine the potential screening use of any particular tool, although its use could be limited for clinicians depending on the immediate and service consequences of false positives. 

    A further caveat is that specificities were not high -- therefore, although the decision maker can be confident that a person is truly low risk if screened out, when someone fails to be screened out as low risk, doctors cannot be certain that this person is not low risk. In other words, many individuals assessed as being at moderate or high risk could be, in fact, low risk.

    Blogger featured on BBC talk show on Aurora massacre

    For those of you who are still tuned in to the Aurora massacre story, I was the featured expert on a BBC radio talk show today, on whether tragedies like this can be prevented. (The short answer, from my perspective, is “No”). Alongside me were the mother of a young man who was at the theater, another man from the local community of Aurora, and a survivor of the recent massacre in Oslo, Norway. We four were on similar wavelengths, but things got a bit heated when a psychologist from California called in to say that more could and should have been done to prevent the killings by the Man Who Has No Name.
