Among male MDOs, R&R participation was associated with improvements in social-cognitive skills, some of which were maintained for up to 12 months post-treatment. Our finding that programme completers do better may reflect pre-treatment patient characteristics. This study establishes that multi-site RCTs can be conducted in medium-secure forensic units.

Studies evaluating the implementation of cognitive skills programs with mentally disordered offenders (MDOs) have reported high dropout rates, but little is known about the factors associated with treatment noncompletion. The authors analyzed data from the first randomized controlled trial of the Reasoning and Rehabilitation (R&R) program with MDOs to determine predictors of treatment dropout. Patients with psychotic disorders were recruited from medium-secure hospitals in the United Kingdom. Fifty percent of the 44 participants allocated to receive R&R prematurely terminated treatment. Program dropout was significantly predicted by scores on the Clinical and Risk Management scales of the Historical, Clinical, Risk Management—20, Factor 2 scores of the Psychopathy Checklist—Screening Version, antisocial personality disorder (ASPD), psychopathy, and recent violence. Psychopathy, ASPD, and recent violence emerged as the strongest predictors of dropout in multivariate analyses. Strategies to improve treatment retention should be targeted at MDOs who display high levels of impulsivity, poor behavioral controls, and antisocial or psychopathic traits.

R&R leads to a reduction in incidents of antisocial behavior in MDO populations, with potentially greater impact on those who complete treatment.

BackgroundIt has been suggested that people with psychopathic disorders lack empathy because they have deficits in processing distress cues (e.g. fearful facial expressions).AimsTo investigate brain function when individuals with psychopathy and a control group process facial emotion.MethodUsing event-related functional magnetic resonance imaging we compared six people scoring ⩾25 on the Hare Psychopathy Checklist–Revised and nine non-psychopathic healthy volunteers during an implicit emotion processing task using fearful, happy and neutral faces.ResultsThe psychopathy group showed significantly less activation than the control group in fusiform and extrastriate cortices when processing both facial emotions. However, emotion type affected response pattern. Both groups increased fusiform and extrastriate cortex activation when processing happy faces compared with neutral faces, but this increase was significantly smaller in the psychopathy group. In contrast, when processing fearful faces compared with neutral faces, the control group showed increased activation but the psychopathy group decreased activation in the fusiform gyrus.ConclusionsPeople with psychopathy have biological differences from controls when processing facial emotion, and the pattern of response differs according to emotion type.
