Static-99R Norms and Cross-Cultural Validity for Australian Aboriginal and Non-Aboriginal Men Convicted of Sexual Offences.

This study examined Static-99R normative data and cross-cultural validity in a sample of 811 Aboriginal and 3257 non-Aboriginal Australian men (N = 4068) serving custodial orders for sexual offences in New South Wales (NSW), Australia. Aboriginal men scored significantly higher on the Static-99R than non-Aboriginal men (M = 4.39 vs. 2.61) and were more likely to be represented in higher categories of risk. The Static-99R showed good discrimination performance for the total sample (AUC = .76; 95% CI = [.73-.80]) and acceptable calibration to expected reoffending rates for routine samples, with slight tendencies towards overestimation. Discrimination accuracy was lower for Aboriginal men (AUC = .68; 95% CI = [.60-77]) than non-Aboriginal men (AUC = .78; 95% CI = [.74-83]) although was significantly better than chance for both groups. Additional analyses indicated that cross-cultural differences in discrimination were partly associated with variance in sample composition between groups. This is the first Australian study to find evidence for significant predictive validity of the Static-99R with Aboriginal men, and while further research is needed, the results provide initial support for cross-cultural applications of the measure in local criminal justice settings.

Relationships Between Treatment Delivery, Program Attrition, and Reoffending Outcomes in an Intensive Custodial Sex Offender Program.

Retention of sex offenders to the completion of treatment is critical to program adherence to risk need responsivity (RNR) principles; however, it is also important to consider the potential interaction between attrition and treatment outcomes such as reoffending. The first aim of this study was to evaluate the influence of changes to treatment delivery in a residential sex offender treatment program (SOTP), including introduction of rolling groups and systematic emphasis on positive therapist characteristics, on likelihood of program noncompletion ( n = 652). Pooled regression modeling indicated that these operational interventions were associated with a significantly increased likelihood of program completion. We also examined whether variance in rates of participant attrition was related to reoffending outcomes for program completers ( n = 494). Incidence of attrition within completing participants' treatment cohorts had a significant negative association with hazard of sexual reoffending that was not accounted for by pretreatment risk. Results are discussed in terms of their implications for treatment delivery processes that aim to optimize both participant retention and treatment effectiveness.

Within-treatment change in antisocial attitudes and reoffending in a large sample of custodial and community offenders.

This study tested evidence for antisocial attitudes as a mechanism of change in offender treatment by examining whether the Measures of Antisocial Attitudes and Associates (MCAA) and within-treatment change in scores on this scale have predictive validity for risk of reoffending. Pretreatment and posttreatment scores on the MCAA were obtained from a large sample of 1,858 offenders who had completed offender treatment programs while in custody (n = 854) or in the community (n = 1,004). Individual within-treatment change was calculated with simple difference scores as well as categorizations of clinically significant change. Results showed that discrete scores on a number of MCAA measures were associated with reoffending hazard at pretreatment and at posttreatment. Change over treatment was also highly significant at the group level whereas a modest proportion of offenders achieved clinically significant change. None of the measures of within-treatment change were significantly associated with reoffending, however. The results suggest that self-reported antisocial attitudes may not be a valid indicator of causal mechanisms of treatment or change in offenders' risk of reoffending as a result of completing treatment.

Treatment of opioid dependence with depot buprenorphine (CAM2038) in custodial settings.

BACKGROUND AND AIMS: Opioid agonist treatment is effective but resource intensive to administer safely in custodial settings, leading to significant under-treatment of opioid dependence in these settings world-wide. This study assessed the safety of subcutaneous slow-release depot buprenorphine in custody. DESIGN: Open-label, non-randomized trial. SETTING: Correctional centres in New South Wales, Australia. PARTICIPANTS: Sixty-seven men and women, aged ≥ 18 years of various security classifications with a diagnosis of moderate to severe DSM-5 opioid use disorder currently serving a custodial sentence of ≥ 6 months were recruited between November 2018 and July 2019. Patients not in opioid agonist treatment at recruitment commenced depot buprenorphine; patients already stable on oral methadone treatment were recruited to the comparison arm. INTERVENTION AND COMPARATOR: Depot buprenorphine (CAM2038 weekly for 4 weeks then monthly) and daily oral methadone. MEASUREMENTS: Safety was assessed by adverse event (AE) monitoring and physical examinations at every visit. Participants were administered a survey assessing self-reported diversion and substance use at baseline and weeks 4 and 16. FINDINGS: Retention in depot buprenorphine treatment was 92.3%. Ninety-four per cent of patients reported at least one adverse event, typically mild and transient. No diversion was identified. The prevalence of self-reported non-prescribed opioid use among depot buprenorphine patients decreased significantly between baseline (97%) and week 16 (12%, odds ratio = 0.0035, 95% confidence interval = 0.0007-0.018, P < 0.0001). CONCLUSIONS: This first study of depot buprenorphine in custodial settings showed treatment retention and outcomes comparable to those observed in community settings and for other opioid agonist treatment used in custodial settings, without increased risk of diversion.

Maintaining Safety in the Prison Environment: A Multilevel Analysis of Inmate Victimisation in Assaults.

Theoretical models of victimisation emphasise the importance of context. However, few studies have assessed the influence of prison environmental variables on inmate harm in physical assaults. This study used a multilevel model approach to examine individual- and facility-level factors associated with the incidence of assaults among inmates housed at correctional centres in New South Wales, Australia. Results supported proposals that institutional routines and conditions may have an influence on risk. Inmates, who spent less time in employment, were placed in special housing arrangements such as protection, or were located in sites with higher security designations or longer routine hours out of cells were more likely to be harmed in assaults. In addition, more than 40% of variance in assaults was associated with differences across correctional centre sites. We draw on routine activities theory to explain relationships between different prison contexts, provision of guardianship, and exposure to motivated offenders in assault outcomes.
