Group psychotherapy with adolescents encompasses treatment of several individuals between 12 and 19 years old at one time. The advantages of this modality include convenience, ongoing assessment, psychoeducation, social comparison and support, natural surrounding, engagement, and motivation. Psychodynamic group psychotherapy centres on the idea that behaviour and emotional responses originate in the internal world, and its focus is on intrapsychic problems and the patient’s past. Interpersonal psychotherapy targets problem areas within the patient’s current interpersonal relationships and is focused on the here-and-now. Mentalization-based group psychotherapy facilitates the development of mentalization by evoking reflection and understanding of oneself and their relationships with others. Cognitive behavioural group psychotherapy is based on the idea that thoughts, actions, and feelings are interconnected. The goal of this model is teaching the patients strategies to cope with and restructure distorted thoughts. Many studies support the efficacy of group psychotherapy as comparable to individual psychotherapy. However, there is need for further research on which modalities or combination therapies are the most effective. This paper also presents several vignettes lead as psychodynamic group therapy.
