Trial results for a study investigating Acceptance and Commitment Therapy to Improve Social Support for Veterans With PTSD (ACT-SS) were posted on ClinicalTrials.gov on 2026-02-13, with 107 participants enrolled.
Background
Veterans with Post-traumatic Stress Disorder (PTSD) frequently experience impaired social relationships and inadequate social support. The negative consequences of poor social support are particularly concerning for this population, as they often perceive the world as dangerous, view their social support network as a threat, and may avoid members of their support network to enhance perceived safety. This project aimed to evaluate the efficacy of Acceptance and Commitment Therapy to Improve Social Support for Veterans with PTSD (ACT-SS), a treatment designed to help veterans with PTSD enhance their social support.
Trial design
This completed study, designated as Phase NA, enrolled 107 participants diagnosed with Post-traumatic Stress Disorder. The trial evaluated Acceptance and Commitment Therapy to Improve Social Support (ACT-SS) against Present-Centered Therapy, focusing on improving social support for veterans with PTSD.
Key results
The trial reported several key measurements related to changes in social adjustment and social support:
- Change in the Social Adjustment Scale-Self Report (Units on a Scale):
- For the Acceptance and Commitment Therapy to Improve Social Support group, mean changes were 3.384 (Standard Deviation 0.674), 2.974 (Standard Deviation 0.78), 3.15 (Standard Deviation 0.822), and 2.842 (Standard Deviation 0.73).
- For the Present-Centered Therapy group, mean changes were 3.344 (Standard Deviation 0.894), 2.99 (Standard Deviation 0.85), 3.061 (Standard Deviation 0.896), and 3.139 (Standard Deviation 1.077).
- Change in the MOS Social Support Survey (Units on a Scale):
- For the Acceptance and Commitment Therapy to Improve Social Support group, mean changes were 2.922 (Standard Deviation 1.057) and 3.2 (Standard Deviation 1.168).
- For the Present-Centered Therapy group, mean changes were 3.061 (Standard Deviation 1.141) and 3.171 (Standard Deviation 1.138).
What this means
The posted results provide specific mean changes and standard deviations for both Acceptance and Commitment Therapy to Improve Social Support (ACT-SS) and Present-Centered Therapy in veterans with PTSD. These measurements, derived from the Social Adjustment Scale-Self Report and the MOS Social Support Survey, indicate the observed shifts in social adjustment and support within each treatment group. Without comparative analyses or statistical significance values, the data offers a descriptive overview of the outcomes for the 107 participants in this study.
