Submitted in fulfillment of the requirements for the Ph.D. (Community Psychology) degree in the Department of Psychology at the University of Zululand, South Africa, 2009. / The researcher developed an ubuntu re-cultivation programme, titled "the Enhancement of Interpersonal Effectiveness" (EIE), for reducing aggressive antisocial behaviour through education and training workshop sessions that encourage participatory learning. The programme was applied on 16 incarcerated male indigenous African offenders in a maximum security prison. The participants ranged in age between 26 and 40 years (mean=3I.I years) and their education stretched from Grade 7 to 12 (mean Grade 10.2). Residential accommodation split the participants into two groups of 9 and 7, which made their facilitation manageable. Baseline performances of participants were established on the Carlson Psychological Survey (CPS) and the Aggression Questionnaire (AQ). The profiles of the CPS showed that the participants had entrenched antisocial behaviour lifestyles and manifestations of feelings of ill-health which included anxiety and depression. The AQ revealed tendencies towards high levels of aggression, anger and hostility. Four, one hourly EIE intervention sessions, were administered per week for six weeks. Post-intervention profile analyses of the AQ revealed significant reductions in 10 of the 16 participants. The reductions occurred in an average of two of the following 5 AQ components: anger, hostility, physical aggression, verbal aggression and indirect aggression. There were also reductions of antisocial ideation on the CPS of half of the participants. The CPS profiles also showed remission of anxiety and depression in 10 participants. The EIE Examination Assignment and the Programme Evaluation Questionnaire indicated that the majority of participants increased their knowledge and skills for constructive social relationships. The findings support the recommendation for the inclusion of EIE as a regular psychological education and training programme for male indigenous African offenders in the correctional centre and other correctional centres with a climate conducive for learning and development.
