The following study is an evaluation of the Moderate Intensity Family Violence Prevention Program (MIFVPP). The sample consisted of 298 male federal offenders who participated in the MIFVPP while incarcerated or on release within the community. Participants were assessed pre-, mid-, and postprogram using an assessment battery consisting of self-report questionnaires and facilitator-rated evaluation scales. Results of the study found uniform and significant (p < .001) improvement for pre and post program change in the self-report questionnaires and in the facilitator ratings. A positive improvement in motivation, whether assessed by the participant or facilitator, was associated with improvement in program outcomes and significant within, between, and interaction effects were found when participant program performance over time was compared among grouped postprogram ratings of motivation. The implication for the efficacy of addressing offender motivation to change in intimate partner violence (IPV) interventions is discussed.

This study is an evaluation of pre-postprogram change associated with the High Intensity Family Violence Prevention Program (HIFVPP) for incarcerated male offenders who are perpetrators of Intimate Partner Violence (IPV). The sample consists of 159 male offenders who participated in the HIFVPP while incarcerated. Participants were assessed pre-, mid-, and postprogram using an assessment battery consisting of self-report questionnaires and facilitator-rated evaluation scales. Results found uniform and significant (p < .001) improvement for pre- and postprogram change in the self-report questionnaires and in the facilitator ratings. A positive improvement in motivation, whether assessed by the participant or facilitator, was associated with improvement in program outcomes and significant within, between, and interaction effects were found when participant program performance over time was compared among grouped postprogram ratings of motivation. The implication for the efficacy of addressing offender motivation to change in IPV interventions is discussed.

Aim/Background Victim age polymorphism occurs when someone offends against victims that span multiple age groups (e.g., child and adult victims). There is a need to better understand the correlates of age polymorphism, as clinicians are often asked about risk of offending against victims who may differ from the index offence victim as part of their risk formulation. The present study examines several potential correlates of age polymorphism: psychopathy, sexual preoccupation, multiple paraphilias, psychosis, and substance use disorders. Materials/Method Analyses were conducted using secondary clinical assessment data from a provincial forensic sexual behaviour program. The sample included 387 men with two or more contact sexual offence victims. The assessment data in the archival database included comprehensive information about victim age, as well as standardized assessment measures and diagnostic/clinical impressions. Results There were no significant associations between age polymorphism and psychopathy, multiple paraphilias, sexual preoccupation, psychosis, and substance use disorders. The only significant difference that emerged was that men who offended against victims 16 or older had a higher mean score on a measure of drug misuse than those who offended against victims 6 to 11. Most of the analyses produced small effects. Conclusion Our findings did not identify significant correlates of age polymorphism when restricting analyses to those men who offended against two or more victims. We consider key methodological differences that may have impacted our findings, as well as the need for rigorously designed research to develop a comprehensive model of age polymorphism.
