The Effect of Self Efficacy and Meaning in Life on Posttraumatic Stress Disorder and Depression Severity Among Veterans

ObjectiveThe current study examined the relationships among combat exposure, presence of and search for meaning in life, general and social self-efficacy, and both posttraumatic stress disorder (PTSD) and depression symptom severity for a Veteran sample (N = 93). MethodParticipants completed an online survey comprising the Combat Exposure Scale, Meaning in Life Questionnaire, Self-Efficacy Scale, Depression subscale of the Depression, Anxiety, Stress Scales-21, and PTSD Checklist-Specific Stressor version. The majority of participants were male and Caucasian. Participants served in various service eras ResultsTo determine factors that predicted PTSD and depression severity, separate hierarchical linear regressions were performed. In the final PTSD model, rank, combat exposure, and general self-efficacy were significant predictors, with officer rank, lower combat exposure, and higher general self-efficacy associated with lower PTSD severity. The interaction between combat exposure and general self-efficacy was also significant, with self-efficacy moderating the relationship between combat exposure and PTSD severity. For depression, rank, presence of meaning in life, and general self-efficacy were significant predictors in the model, with officer rank, higher presence of meaning in life, and general self-efficacy associated with lower depression severity. ConclusionA focus on strengthening self-efficacy may assist with lower levels of PTSD and depression symptomatology after combat trauma.
