Vulnerability and resilience among older South Korean Vietnam war veterans: A latent profile analysis.

Relatively little is known about South Korean Vietnam War veterans, despite their being the second largest contingent of troops during the Vietnam War. Earlier research found elevated levels (39%) of post-traumatic stress disorder (PTSD) in this older population, due to high exposure to combat and malevolent environments (Lee et al., 2020). The present study investigated classes of vulnerability and resilience among older South Korean Vietnam War veterans, using a latent profile analysis (LPA) on PTSD symptoms, late onset stress symptomology (LOSS), and mental well-being (MWB). The sample consisted of 367 older male veterans from South Korea ( M _age = 72, SD = 2.66) who completed surveys. The LPA yielded five classes. The largest (38%) was Average (average PTSD, LOSS, and MWB levels), and the second largest (31%) was characterized by Moderate Distress (moderately high PTSD and LOSS, average MWB). A small group (13%) reported Low Affect (low PTSD, LOSS, and MWB levels), and 7% expressed Severe Distress (high LOSS and PTSD levels, average MWB). Only a small percentage (12%) were characterized by Resilience (low PTSD, average LOSS, high MWB). Optimism, positive appraisals of military service, and social support from family, significant others, friends, and military peers were highest among veterans in the Resilience class. To our knowledge, this is the first study of resilience among East Asian military veterans, and more research is needed on how resilience can be improved.
