Abstract: Violence risk assessment instruments are used to inform key decisions about treatment planning and delivery, release on parole, and intensity of supervision in the community. Yet, limited published information is available about psychometric properties other than predictive validity. The purpose of this study was to examine the factor structure and measurement invariance across pretreatment to posttreatment and cultural groups of one of the most widely used violence risk assessment instruments, the Violence Risk Scale (VRS). Data from 366 completed assessments at preintervention and postintervention phases for adults serving custodial sentences for violent offenses in an Australian jurisdiction were subject to confirmatory factor analysis. The results indicated four intercorrelated but conceptually independent dimensions. Furthermore, measurement invariance was established across pretreatement and posttreatment occasions and different cultural groups. However, latent means comparison revealed significant difference across cultural groups, raising questions about sensitivity and generalizability of the VRS when used with erse cultural groups.

Abstract: The veracity of self-report is often questioned, especially in anger, which is particularly susceptible to social desirability bias (SDB). However, could tests of SDB be themselves susceptible to bias? This study aimed to replicate the inverse correlation between a common test of SDB and a test of anger, to deconstruct this relationship according to anger-related versus non-anger-related items, and to reevaluate factor structure and reliability of the SDB test. More than 200 students were administered the Marlowe-Crowne Social Desirability Scale Short Version [M-C1(10)] and the Anger Parameters Scale (APS). Results confirmed that anger and SDB scores were significantly and inversely correlated. This intercorrelation became nonsignificant when the 4 anger-related items were omitted from the M-C1(10). Confirmatory factor analyses showed excellent fit for a model comprising anger items of the M-C1(10) but not for models of the entire instrument or nonanger items. The first model also attained high internal consistency. Thus, the significant negative correlation between anger and SDB is attributable to 4 M-C1(10) anger items, for which low ratings are automatically scored as high SDB this stems from a tenuous assumption that low anger reports are invariably biased. The SDB test risks false positives of faking good and should be used with caution.

Abstract: This study examines the relationships between indicators of offender supervision outcomes and dimensions of positive psychological states (PPS). Results of a confirmatory factor analysis (CFA) revealed that the first-order positive psychology constructs converge to form a higher order construct of PPS which was inversely associated with supervision outcomes. Furthermore, the mediating effect of PPS on the relationship between criminogenic risk factors and all offender supervision outcome variables was statistically significant, suggesting that offenders with heightened PPS are likely to have fewer criminogenic risk factors and are less likely to be reported for technical violation, charged, reconvicted, and imprisoned. The implications of these findings for correctional theory, practice, and policy conclude the article.
