Psychosocial groups within the AOD treatment setting are also much appreciated by clients with co-occurring conditions [764]. Evidence suggests that clients who attend groups consistently and for a longer time period (e.g., for a year) achieve the best results, although positive outcomes can nonetheless be achieved by attending shorter-term groups [765, 766]. Similarly, incorporating creative elements into group interventions, with multiple activities conducted within shorter group sessions, appear to improve treatment outcomes among people with mental health conditions [767]. It is important that such groups are facilitated in such a way as to avoid confrontation. Sustained emotional distress can worsen a number of mental health conditions and a confrontational treatment approach may be harmful to clients with co-occurring conditions [162, 768]. It is important to assess whether the client experiences social anxiety or impairments in social judgement and social skills, as they may appear and feel awkward in group settings [769, 770]. Readers are referred to Mueser and colleagues [770] for a more detailed discussion on the use of group interventions for co-occurring disorders.
