The United States Supreme Court’s 1993 Daubert v. Merrell Dow Pharmaceuticals case established criteria for admitting scientific evidence in federal courts.

The United States Supreme Court’s 1993 Daubert v. Merrell Dow Pharmaceuticals case established criteria for admitting scientific evidence in federal courts. It holds that scientific evidence must be valid, reliable, and relevant, and judges are required to be “gatekeepers” of evidence by screening out evidence that has not been empirically tested or vetted through the academic community. Yet, little is known about whether psychological assessment tools are subjected to scrutiny through the standards courts are supposed to apply. In three different studies, from the perspectives of judges, attorneys, and forensic mental health experts, the authors investigate whether psychological assessment evidence is being challenged. Information was collected on participants’ experiences with challenges to psychological assessments. Judges and lawyers completed a series of experimental case vignettes to assess their decision-making about legal admissibility of different qualities of psychological assessments. It was hypothesized they would not distinguish between low- and high-quality psychological assessments in admissibility. Bayesian model selection methods did not support the null hypothesis, however. It was found attorneys differentiate between the conditions. The rates in which legal professionals and forensic mental health evaluators experienced challenges were also higher than was expected. These positive findings show there is some degree of gatekeeping psychological assessment evidence in the courts.

Description

We conducted an international survey in which forensic examiners who were members of professional associations described their two most recent forensic evaluations (N=434 experts, 868 cases), focusing on the use of structured assessment tools to aid expert judgment. This study describes:

1. The relative frequency of various forensic referrals.
2. What tools

We conducted an international survey in which forensic examiners who were members of professional associations described their two most recent forensic evaluations (N=434 experts, 868 cases), focusing on the use of structured assessment tools to aid expert judgment. This study describes:

1. The relative frequency of various forensic referrals.
2. What tools are used globally.
3. Frequency and type of structured tools used.
4. Practitioners’ rationales for using/not using tools.

We provide general descriptive information for various referrals. We found most evaluations used tools (74.2%) and used several (on average 4). We noted the extreme variety in tools used (286 different tools). We discuss the implications of these findings and provide suggestions for improving the reliability and validity of forensic expert judgment methods. We conclude with a call for an assessment approach that seeks structured decision methods to advance greater efficiency in the use and integration of case-relevant information.

Prisoners sentenced to death must be competent for execution before they can actually be executed (Ford v. Wainwright, 1986). The decision for many mental health professionals whether to conduct competence for execution evaluations may be fraught with complex ethical issues. Mental health professionals who do not personally support capital punishment

Prisoners sentenced to death must be competent for execution before they can actually be executed (Ford v. Wainwright, 1986). The decision for many mental health professionals whether to conduct competence for execution evaluations may be fraught with complex ethical issues. Mental health professionals who do not personally support capital punishment may have a particularly difficult decision to make in this regard but should seriously consider the consequences of their decisions. This article applies Bush, Connell, and Denney’s (2006) eight-step ethical decision-making model to the ethicality of deciding to or abstaining from conducting competence for execution evaluations. This article does not propose what decisions an individual evaluator should make regarding this work, but rather presents a systematic guide for mental health professionals (particularly those who do not support capital punishment) to consider.

This study examined the scope and components of mitigation assessments in a first effort to develop some guidelines for conducting mitigation evaluations.

This study examined the scope and components of mitigation assessments in a first effort to develop some guidelines for conducting mitigation evaluations. Using the Mitigation Evaluations Survey (MES) we developed for this research, we surveyed 266 psychologists about the characteristics and content of mitigation evaluations. A high percentage of participants endorsed each of the 14 content areas presented in the MES as essential or recommended for inclusion in mitigation evaluations. However, when the participants were given a hypothetical open-ended referral question regarding a mitigation evaluation, fewer participants included all 14 content areas in their responses. This discrepancy as well as information regarding the qualifications and expertise of the participants is discussed.
