A new randomized controlled trial provides the first research-based evidence of Internal Family Systems (IFS) therapy’s efficacy for treating posttraumatic stress disorder. Researchers at Cambridge Health Alliance, a Harvard Medical School affiliate, developed the “Program for Alleviating and Resolving Trauma and Stress” (PARTS), an online group-based IFS intervention tested on 60 PTSD patients.
IFS is an increasingly popular contemplative mental health intervention that integrates elements from various psychotherapeutic approaches and has been shown to enhance de-centering and self-compassion, both important in PTSD treatment. Participants were randomly assigned to either the PARTS intervention or an active control arm called Nature-Based Stress Reduction for Trauma Survivors. Patients in the PARTS treatment arm reported higher levels of group satisfaction than the control arm, with most PARTS participants rating the group experience as excellent at statistically significantly higher proportions than the control. PARTS participants attended on average 12.8 of 16 total sessions, significantly more than the 10 sessions attended by the control group.
Treatment Outcomes and Significance
Both treatment arms led to statistically significant large reductions in PTSD symptoms, consistent with emerging findings from large-scale meta-analyses showing no significant differences between multiple popular psychotherapies for PTSD. The study demonstrated the feasibility and acceptability of PARTS as an accessible and affordable group-based online treatment program in community mental health settings. This is particularly significant given that community mental health centers, which play a vital role in providing PTSD services, struggle with staff shortages and long wait times. Group-based interventions can benefit patients who are marginalized or socially isolated and help financially strapped clinics provide cost-effective care. The study had limitations including limited funding and resources, a small sample size, and a primary outcome measure that does not capture symptoms of complex trauma. Nonetheless, it demonstrated PARTS’ potential as an accessible treatment option for PTSD in community settings.
