A Mixed-Methods Examination of Interdisciplinary Strategies for Addressing Trauma and Chronic Pain in Group Therapy

Background/Objectives: Trauma and chronic pain frequently co-occur and mutually reinforce functional impairment, yet few counseling interventions integrate somatic and psychological approaches. This study had two primary objectives: (1) to evaluate the feasibility and acceptability of an interdisciplinary trauma–chronic pain group intervention, and (2) to explore preliminary clinical outcomes related to trauma symptoms, fear of movement, and pain through an interdisciplinary group intervention combining trauma-informed counseling with physical therapy grounded in Postural Restoration Institute (PRI) principles. Methods: A convergent mixed-methods design was used, wherein quantitative and qualitative data were collected concurrently, analyzed separately, and integrated during interpretation to provide a comprehensive understanding of intervention outcomes. Fifteen adults with chronic pain (≥3 months) and clinically significant trauma symptoms (PCL-5 ≥ 31) completed a six-week, 90 min group program co-facilitated by a counselor and a physical therapist. Quantitative measures included weekly pain (BPI), pre/post trauma symptoms (PCL-5), fear of movement (TSK), group climate (GCQ), and postural neutrality. Qualitative data included weekly journals, photographs, open-ended post-surveys, and focus groups, analyzed using inductive thematic analysis. Results: Participants attended most sessions (96.7% overall attendance) with no dropouts and high fidelity (mean 2.89/3). Pre/post analyses indicated statistically significant within-group reductions in trauma symptoms and fear of movement and improvements in pain and postural neutrality; however, findings should be interpreted as preliminary given the pilot design and small sample size. Qualitative themes highlighted the persistent burden of pain/trauma, increased mind–body awareness, emotional regulation, and validation through group support. Conclusions: An interdisciplinary, PRI-informed, trauma-informed group model was obtained. This model demonstrates preliminary feasibility and acceptability and suggests potential benefit; however, findings are derived from a small, non-controlled pilot study and require further validation. Future research should employ larger, controlled, and longitudinal designs.
