Group interpersonal psychotherapy for veterans with posttraumatic stress disorder: a pilot study

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Posttraumatic stress disorder (PTSD) significantly impacts veterans' interpersonal functioning and psychological well-being.
• Vietnam veterans with PTSD often experience persistent interpersonal difficulties and psychological distress.
• Interpersonal psychotherapy (IPT) is an evidence-based treatment for depression and has been adapted for PTSD.

Purpose of the Study:

• To evaluate the efficacy of group-based interpersonal psychotherapy (IPT-G) in reducing interpersonal difficulties and psychological distress among male Vietnam veterans with PTSD.
• To assess the maintenance of treatment gains over a 4-month follow-up period.

Main Methods:

• A sample of nine male Vietnam veterans diagnosed with PTSD received IPT-G.
• Standardized measures assessed posttraumatic stress, depression, interpersonal problems, and global functioning pre- and posttreatment, and at 2- and 4-month follow-ups.
• Individual (reliable change indices) and group (repeated measures ANOVAs) analyses were employed.

Main Results:

• Significant improvements were observed in PTSD and depressive symptoms, which were maintained at follow-up.
• Interpersonal and global functioning showed initial improvements but were not consistently maintained at follow-up.
• Qualitative feedback indicated reduced anger and stress, alongside enhanced interpersonal relationships.

Conclusions:

• IPT-G demonstrates potential as an effective intervention for improving interpersonal functioning and alleviating psychological distress in Vietnam veterans with PTSD.
• The findings suggest that while IPT-G effectively reduces PTSD and depressive symptoms, further research into relapse prevention strategies is warranted to sustain all treatment gains.
• Future studies should explore methods to enhance the long-term maintenance of interpersonal and global functioning improvements.
