Use of the MMPI-2 to predict the employment continuation and performance ratings of recently hired police officers

The MMPI-2 is one of the most frequently employed instruments for the selection of police officers. Serafino and Serafino (1997) collected data which involved information about employment continuation and ratings by supervisors of 32 police officers who had recently been hired and who had been given the MMPI-2 during the hiring process. In this study, the Paranoia Obvious (Pa) and Paranoia Subtle (Ps) scales proved to be the significant. Pa Subtle correlated with removal whereas Pa Obvious correlated with rating. Higher scores on Pa Subtle correlated significantly with being removed from the job, whereas low scores on the Pa Obvious correlated with higher ratings of performance by supervisors. Discussion of the results involved the fact that Subtle Pa scores would suggest paranoid tendencies not easily detected during the interview. Since most high Pa Obvious individuals would have been eliminated in the hiring process, expression of this tendency was at a low level after being hired but if present resulted in low ratings. Significant predictors were noted to be very much a function of the type of criterion variable employed in the study.     

Construct validity,reliability and predictive validity of the dynamic risk assessment and management system (DRAMS) in offenders with intellectual disability

Background. There have been a number of developments in the assessment of dynamic risk in the criminological literature. The dynamic risk assessment and management system (DRAMS) has been developed to facilitate the measurement of dynamic factors of risk for offenders with intellectual disability. Method. The study was designed to assess the construct validity, reliability and predictive utility of the DRAMS in 23 male forensic patients in a high secure setting. Predictions were made against independently collected incident data. Concurrent validity was assessed against the Ward Anger Rating Scale (WARS). Results. A reformulation of the individual section variables according to convergent and discriminant correlational analysis revealed Cronbach's alpha levels of >.8 for all sections apart from mood (alpha .750) and items retained to facilitate clinical information (alpha ?.017). Two hundred pairs of WARS and DRAMS assessments revealed orderly sectional correlations. The sections of mood, antisocial behaviour, and intolerance/agreeableness predicted incidents with a medium effect size as did total DRAMS score. There were highly significant differences between assessments taken 1 or 2 days prior to an incident and control assessments conducted at least 7 days from an incident. Conclusions. The reformulated DRAMS has good construct and concurrent validity. It appears to be a reliable assessment tool and informs on risk levels relating to stable and acute proximal factors. It appears as an important addition to the utility of risk assessments for this population.
