Group-based interpersonal psychotherapy for posttraumatic stress disorder: theoretical and clinical aspects.

Posttraumatic stress disorder (PTSD) is a condition that engenders both symptomatic distress and severe disruption in interpersonal and social functioning. Most of the empirical research on treatment has emphasized interventions that aim to alleviate the symptoms of PTSD, despite the persisting impairments in social, occupational, and interpersonal functioning. In clinical practice, achieving relief from symptoms such as irritability or phobic avoidance is a worthwhile goal, yet significant distress and disability derived from disruptions to interpersonal attachments, social networks, and confiding intimate relationships persist. Interpersonal psychotherapy (IPT) has been shown to be efficacious in research settings for depression and eating disorders, in both group and individual formats. Recent pilot data also suggests the potential usefulness of IPT in anxiety disorders. The aim of this paper is to provide a rationale for the use of group-based IPT as an intervention for PTSD as part of a management package, arguing from theoretical and clinical viewpoints. The integration of IPT therapeutic processes with the therapeutic group process is discussed, and a detailed case discussion is presented as an illustration.
