Personality traits as predictors of occupational performance and life satisfaction among mentally disordered offenders.

The study investigated to what extent personality traits, e.g. socialization, proneness for anxiety, aggression and hostility were associated with and predictive of self-reported and observed occupational performance and perceived life satisfaction among male mentally disordered offenders (MDOs). Also, subjects with psychopathic-related personality traits were compared with subjects without such traits regarding demographic data and dependent variables. The MDOs were included from the Swedish National Board of Forensic Medicine. A total of 55 subjects were visited at their hospital ward for data collection with the Karolinska Scales of Personality (KSP), Capability to Perform Daily Occupation (CPDO), Allen Cognitive Level Screen (ACLS) and the Manchester Quality of Life Scale (MANSA). Seven KSP scales and two KSP factors correlated significantly with the dependent variables. Regression analyses revealed that the KSP Socialization scale, the KSP Anxiety-proneness and Psychopathy factors were the most important predictors. Subjects with psychopathy differed from remaining groups by having more conduct disorders before 15 years, being more often brought up in outcasted families and less subjected to measures of pupil welfare activities. The life history was concluded to be important influencing occupational performance and life satisfaction. Subjects with high anxiety proneness should be given attention in treatment planning.
