From Combat to Civilian Life: An Integrative Review of Mental Health Challenges and Recovery Pathways for Warzone Veterans

Abstract

Background: The mental health of military veterans returning from warzones represents a critical public health concern with profound individual and societal implications. Understanding the complex interplay of psychological, physical, and social factors affecting this population is essential for developing effective interventions and support systems.
Objective: This integrative review synthesizes current evidence on mental health challenges faced by warzone veterans, examining prevalence rates, contributing factors, clinical presentations, and recovery pathways across the deployment cycle and reintegration process.
Methods: A systematic literature search was conducted across multiple databases including MEDLINE, PubMed, LILACS, SciELO, PsycINFO, PsycArticles, CINAHL, Cochrane Central Register of Controlled Trials, SocINDEX, and Academic Search Premier. The search strategy employed the PICo framework (Population, Interest, Context) and utilized Medical Subject Headings including "war disorders," "veterans," "post-traumatic stress disorder," "combat disorders," "psychological warfare," and "warfare." The review focused on peer-reviewed publications examining mental health outcomes in combat-deployed military personnel and veterans from 2001 through 2025. Sixty-two references meeting inclusion criteria were synthesized following established integrative review methodology.
Results: Prevalence rates of PTSD among veterans range from 9% to 31% depending on functional impairment criteria, with substantial comorbidity with depression (up to 70% co-occurrence), anxiety disorders, substance use disorders, and chronic pain. The triad of pain, PTSD, and depression demonstrates complex bidirectional relationships requiring integrated treatment approaches. Adding to this complexity, traumatic brain injury, particularly blast-related, presents unique symptom presentations and treatment challenges, with individuals with TBI having twice the likelihood of developing depressive symptoms compared to those without TBI. Reintegration difficulties encompass psychological adaptation, sociocultural transition challenges, identity reconstruction, and moral injury. Emerging evidence highlights the protective roles of resilience, social support, and positive spiritual coping, while identifying moral injury as a distinct clinical concern requiring targeted intervention.
Conclusions: Warzone veterans experience multifaceted mental health challenges requiring comprehensive, culturally competent, and trauma-informed care approaches. Future research priorities include longitudinal studies examining reintegration trajectories, comparative effectiveness trials of interventions, investigation of protective factors, and implementation research to translate evidence into practice. The findings support development of comprehensive care models addressing the full spectrum of veteran mental health needs across the lifespan.
