This study was a retrospective evaluation of the efficacy of the pilot New Zealand Violence Prevention Project in reducing recidivism among 32 adult male violent offenders. The study employed a matched group, quasi-experimental design. Results from an approximate 5-year follow-up of reconviction data showed that, compared to mainstream corrections practices, treatment was not associated with any significant reductions on multiple recidivism outcome measures. A survival analysis showed the treatment (completer) group had slightly better conviction survival than the control group, but survival curves for the two conditions did not differ reliably. Effect size comparisons, a technique less influenced by small samples, revealed modest but consistently greater reductions on pre- to post-intervention measures of recidivism for the completer group. The implications of such findings for the design of offender treatment programmes are discussed.--AUTHOR'S ABSTRACT
