New Zealand's special treatment units: the development and implementation of intensive treatment for high-risk male prisoners

In the late 1980s, New Zealand developed two highly innovative residential treatment programmes for serious offenders that blended together the strengths of structured cognitive behavioural group programmes and therapeutic community approaches. Since the mid-1990s this hybrid model – recently advocated as a fruitful direction for future offender programme development – was adopted and further refined for use in New Zealand's four high-risk special treatment units (HRSTUs). We outline the HRSTU model, noting the challenges and potential benefits of providing an intervention that integrates therapy, resocialisation and reintegration experiences for high-risk, high need, low responsivity clients: many with significant psychopathic features. On average, the majority of those referred to HRSTUs complete the programme and make small but significant amounts of change on important treatment goals. But most changes remain tentative, suggesting the importance of more supportive aftercare. Although an earlier evaluation of the first unit to open found the programme to be modestly effective in reducing recidivism, an outcome evaluation currently underway will help establish whether improvements since that time are associated with reductions in disciplinary infractions and recidivism.     

The predictive and convergent validity of a psychometric battery used to assess sexual offenders in a treatment programme: an 18-year follow-up

Abstract

This study examined sex offender risk and treatment change based on a battery of psychometric assessment measures administered to 267 treated adult Canadian federal sex offenders followed up an average 18 years post release. Several significant pre–post changes that were frequently moderate in magnitude (d>.50) were observed across these measures. A factor analysis of the psychometric battery generated three broad need domains consistent with the extant literature that were labelled Socioemotional Functioning, Anger/Hostility, and Misogynist Attitudes. The three need domains and a Need Total, created by their summation, converged with the Violence Risk Scale—Sexual Offender version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003) in conceptually meaningful ways and predicted sexual and violent recidivism to varying degrees. Raw measurements of change obtained from pre-to posttreatment frequently bore weak and non-significant relationships to outcome. However, after creating standardised residual change scores to control for pre-treatment score, treatment changes in the individual measures, need domains and Need Total improved significantly in their prediction of reductions in general and sexual violence.     

The impact of an intensive inpatient violent offender treatment programme on intermediary treatment targets,violence risk and aggressive behaviour in a sample of mentally disordered offenders*

This study examined the impact of an intensive inpatient violent offender treatment programme, Life Minus Violence-Enhanced (LMV-E), on intermediary treatment targets, risk for violence, and aggressive behaviour during treatment in a sample of male mentally disordered offenders. Using quasi-experimental design, offenders who completed LMV-E and a comparison group showed reduced problems with impulsivity and anger regulation and improvements in social problem solving. Aggregate risk for future violence lessened in both treatment and comparison groups, although by a significantly greater degree for the comparison group. The aggressive behaviour of both groups reduced. Completion of the LMV-E conferred additional improvements in some facets of social problem solving and anger regulation. Neither group showed improvements in empathic responses, coping skills or problematic interpersonal style. Overall, these results suggest anger regulation, impulsivity and social problem solving are most amenable to change, that reductions in certain facets of these dynamic risk factors transpires with nonspecific psychiatric inpatient treatment, but that the LMV-E, a cognitive behavioural violence specific psychological treatment, confers greater change in some facets of social problem solving and anger regulation.
