Group therapy in primary care settings for the treatment of posttraumatic stress disorder: A systematic literature review

Abstract

Objective: This systematic review aims to summarize existing literature on group therapy for the treatment of post-traumatic stress disorder (PTSD) in primary care.

Method: A PRISMA systematic literature review was performed through February 26, 2022 identifying existing studies of group trauma therapy in primary care. Articles were included if they discussed group trauma therapy for primary care patients. Bias was assessed based on sample sizes and presence of control groups. Results are presented as a weighted average of the engagement rate and a qualitative description of overlapping study traits.

Results: Four studies of group PTSD treatment within primary care were identified with 70 total patients completing group treatment. The weighted treatment engagement rate was 65%. Each utilized distinct group trauma treatment models and reported significant patient improvements in PTSD symptoms on standardized trauma symptom scales.

Discussion: Group trauma therapy models are available and can be disseminated within primary care settings. Limitations include both the small number of studies and participants.

Conclusion: There have been few studies of group therapy for PTSD in primary care, but these could represent a promising and scalable approach to meet the high need for trauma treatment. Further research is needed regarding implementation feasibility and impact.
