We compared the efficacy of, and adolescents' preferences for, a Cognitive Behavioural (CBT) and Personal Development (PD) Anger Management (AM) group. The CBT group aimed to help adolescents develop skills to manage predominantly reactive aggression. The PD group aimed to enhance motivation to develop less aggressive identities with less use of proactive aggression. Eighteen adolescents were randomly allocated to a 10-session CBT or PD AM Group; seven additional adolescents formed a control group. They completed pre- and post-intervention questionnaires to assess anger expression and control, use of AM coping skills (also completed by carers) and self-image. Participants were also interviewed pre- and post-intervention; transcripts were subjected to Interpretive Phenomenological Analysis. Both treatment groups demonstrated significant improvements in anger coping and self-esteem, relative to the control group. Participants' age was significantly correlated with self-image and anger control outcomes in the CBT group. Qualitative analysis identified factors associated with improved outcomes, particularly regarding participants' age, motivation and readiness to change, engagement in the therapeutic process, group dynamics and emotional expressiveness. Our ability to interpret data clinically was enhanced by the use of a mixed quantitative-qualitative methodology. The results help us to better match interventions to clients.
