When conducting a forensic evaluation, what psychological tests do experts consider acceptable to use? The answer is useful to psychologists making practice decisions but also to the courts, who rely on others’ opinions to base one of the criteria for determining the admissibility of testimony. The author surveyed diplomates in forensic psychology (N 64) regarding both the frequency with which they use and their opinions about the acceptability of a variety of psychological tests in 6 areas of forensic practice. The 6 areas were mental state at the offense, risk for violence, risk for sexual violence, competency to stand trial, competency to waive Miranda rights, and malingering. Results are presented for each practice area, and the implications of these results for the courts, future research, and practice are discussed. As many psychologists are considering entering forensic practice, either in a primary or secondary role, they are uniquely positioned to provide testimony to the court, as compared with other mental health professionals. Other mental health professionals, including psychiatrists, the traditional providers of expert testimony, generally base their opinions solely on their interview of a defendant or plaintiff and on collateral sources (records and interviews of other relevant parties). Psychological tests provide psychologists with a third source of information, and with these three legs on which to rest their opinions, psychologists have a more stable and valid foundation as the basis of their testimony. However, all psychological tests are not created equal; some are more appropriate than others for use in a forensic evaluation. For psychologists entering forensic practice, it is useful to know what tests are used by forensic psychologists; even more pertinent is understanding what tests are appropriate for particular types of forensic evaluations. The answer to this question not only helps guide practice decisions but also addresses an important element that courts use to decide whether an expert’s opinion is admissible at a hearing or trial. Even though it has been 40 years since the courts have officially recognized psychologists’ place as experts to provide testimony (Jenkins v. United States, 1962), the admissibility of testimony based on psychological test results still gets challenged. For the psychologist facing such challenges, it is
