Evidence Integration Review of Multimodal Interventions for PTSD, Social Reintegration, and Economic Stability in Veterans

Objective: This Evidence Integration Review evaluated the effectiveness of multimodal interventions, which targeted physical, psychological, and social outcomes for military veterans. Through a mixed methods approach, this review integrated findings from randomized controlled trials, cross-sectional studies, and qualitative analyses to assess intervention impact and veterans’ lived experiences. Interventions included mindfulness practices, physical activity programs, social support mechanisms, and employment-focused initiatives addressing PTSD, depression, anxiety, and reintegration challenges. Methods: A comprehensive search was conducted across PsycINFO, MEDLINE, CINAHL, and Web of Science for US-based studies published between January 2014 and November 2024. Eligible studies employed quantitative or qualitative designs and examined exercise, mindfulness, or social support. Quantitative data were synthesized using PRISMA guidelines and Julius.ai, while qualitative themes were analyzed in ATLAS.ti. Participants were primarily post-9/11 veterans aged 28.1 to 57.1 years old. Majority of the participants were male (81.8%); however, four studies focused on female veterans. Results: Forty studies involving over 7,500 veterans were included. Interventions showed significant improvements in PTSD, depression, and reintegration. Mindfulness and trauma-focused therapies yielded strong psychological benefits. Social support improved reintegration, and physical activity enhanced resilience and reduced chronic pain. Limitations included dropout, inconsistent adherence, and underrepresentation of female and minority veterans. Conclusions: Multimodal interventions improved veterans well-being but must be inclusive to address systemic barriers. Future research should emphasize longitudinal evaluations, stigma reduction, and digital access to enhance sustainability.
