An actuarial risk assessment instrument can be considered valid if independent investigations using novel samples can replicate the findings of the instrument's development study. In order for a study to qualify as a replication, it has to adhere to the methodological protocol of the development study with respect to key design characteristics, as well as ensuring that manual-recommended guidelines of test administration have been followed. A systematic search was conducted to identify predictive validity studies (N = 84) on three commonly used actuarial instruments: the Violence Risk Appraisal Guide (VRAG), the Sex Offender Risk Appraisal Guide (SORAG), and the Static-99. Sample (sex, age, criminal history) and design (follow-up, attrition, recidivism) characteristics, as well as markers of assessment integrity (scoring reliability, item omissions, prorating procedure), were extracted from 84 studies comprising 108 samples. None of the replications matched the development study of the instrument they were attempting to cross-validate with respect to key sample and design characteristics. Furthermore none of the replications strictly followed the manual-recommended guidelines for the instruments' administration. Additional replication studies that follow the methodological protocols outlined in actuarial instruments' development studies are needed before claims of generalizability can be made.
The role of psychosocial and structural occupational factors in mental health service provision has broadly been researched. However, less is known about the influence of employees’ occupational factors on inmates in correctional treatment settings that mostly seek to apply a milieu-therapeutic approach. Therefore, the present study investigated the relationships between occupational factors (job satisfaction, self-efficacy, and the functionality of the organizational structure) and prison climate, the number of staff members’ sick days as well as inmates’ treatment motivation. Employees (n = 76) of three different correctional treatment units in Berlin, Germany, rated several occupational factors as well as prison climate. At the same time, treatment motivation of n = 232 inmates was assessed. Results showed that higher ratings of prison climate were associated with higher levels of team climate, job satisfaction and the functionality of the organizational structure, but not with self-efficacy and sick days. There was no significant relationship between occupational factors and the perceived safety on the treatment unit. Inmates’ treatment motivation was correlated with all aggregated occupational factors and with average sick days of staff members. Outcomes of this study strongly emphasize the importance of a positive social climate in correctional treatment units for occupational factors of prison staff but also positive treatment outcomes for inmates. Also, in the light of these results, consequences for daily work routine and organizational structure of prisons are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
