Working Alliance and Psychopathy: Linkages to Treatment Outcome in a Sample of Treated Sexual Offenders

The present study examined the working alliance, as measured by the full-length Working Alliance Inventory (WAI), and its association with psychopathy, treatment completion, and recidivism in a sample of 111 incarcerated adult male sexual offenders. The men completed the WAI 3 months into their treatment program, while psychopathy was measured via file-based ratings of the Hare's Psychopathy Checklist-Revised (PCL-R), and outcome data were collected via the Canadian Police Information Centre. The majority (85%) of high PCL-R scoring men (PCL-R 25+) successfully completed their treatment program, and by and large, the men demonstrated strong working alliances with their primary therapists. The WAI scale components showed differential associations with the structural features of psychopathy. Specifically, the Affective facet was significantly associated with weaker Bond scores, while the Lifestyle facet was associated with lower Task scores; these results were upheld after controlling for scores on the other PCL-R facets. Strength of alliance, however, was not significantly associated with any recidivism outcomes, irrespective of controls for psychopathy. Implications for the treatment of offenders with high levels of psychopathic traits are discussed in light of extant findings and unique features of the therapeutic alliance.
