![]() ![]() Research should also investigate whether the PCL will be valuable with adolescent and female populations, as well as forensic and civil psychiatric patients. Research should determine what degree the measures add to predictions of violence beyond that afforded by aggregate measures of a history of violence. Research: The authors state that future research is needed to determine whether one of the psychopathy checklist factors (applicable to all versions) might predict violent and criminal behaviour better than the other. In these cases (especially with Anglo-American males), the PCL is an unequalled measure in determining their specific risk assessments. In addition, psychologists may want to consider the PCL in parole and conditional release decisions, and in hearings on community placement of forensic patients. Practice: The authors state that, there is some merit for psychologists utilising the PCL-R when making probability statements regarding placement decisions in correctional institutions (e.g. Implications of the review for practice and research ![]() In studies addressing deviant sexual arousal and sexual sadism, the effect sizes ranged from 0.47 to 0.77, with a mean effect size of 0.61. ![]() When general recidivism was used as the outcome, the effect sizes ranged from 0.24 to 0.93, with a mean effect size of 0.55. When violence was used as the primary outcome, the effect sizes ranged from 0.42 to 1.92, with a mean effect size of 0.79. The test for heterogeneity of the effect sizes was non significant. The positive and negative predictive values ranged from 29 to 88%, and from 55 to 81%, respectively. The sensitivity for the most commonly reported cut-off score of greater than 25 (from 5 included studies) ranged from 17 to 62%, and the specificity from 80 to 93%. The test characteristics were reported for 10 of the 18 included studies. Thirteen studies (2,390 participants) investigated the ability of the psychopathy checklists to predict violent behaviour, ten their ability to predict recidivism (1,991 participants), and three their ability to predict sexual sadism or deviant sexual arousal (305 participants). A total of 18 PCL or PCL-R studies yielding 29 effect sizes were included in the review. ![]()
