Abstract: Objective: Combat exposure has long-term negative effects in later life, and aspects of service
may be appraised positively, but the long-term effects of combat on well-being in later life is largely unknown. Method: The sample included 1,006 male veterans from the VA Normative Aging Study, surveyed by mail in 1986, 1990, and 1991 (Mage = 62.5, SD = 7.27). They reported on their combat exposure, desirable appraisals of military service, unit cohesion, dispositional optimism, self-rated health, and psychological well-being (PWB), as well as age, military rank, and education. Perceived positive aspects (PPA) of military service was postulated to mediate the effects of combat exposure on PWB. SEM was used to examine both mediating and moderating effects. Results: Age, combat exposure, and optimism had independent effects on PPA, but optimism did not moderate the effect of combat exposure on PPA. Combat exposure had only indirect effects on PWB through the PPA, controlling for the direct effects of optimism. Education had no direct effects on the positive outcomes, but did have indirect effects through optimism. Conclusion: Combat exposure contributes to positive well-being in later life, indirectly through positive appraisals, and this effect was independent of optimism. Thus, these results support the idea that combat veterans should be encouraged to focus on positive aspects of military service, which may serve as resilience resources to facilitate optimal aging.
