The Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5) has been found to consist of various subscales in U.S. Veterans. The current study replicated the dimensional structure of the PCL-5 and examined the associations of PTSD symptoms with combat exposure, mental health, subjective physical health, and eudaimonic well-being among Korean Veterans. The sample included 345 Korean male Veterans who were deployed to the Vietnam War. Confirmatory factor analyses of the PCL-5 supported the superiority of the 7-factor hybrid model consisting of re-experiencing, avoidance, negative affect, anhedonia, externalizing behaviors, anxious arousal, and dysphoric arousal. The subscales showed high internal consistencies, ranging from .80 to .93, and were significantly correlated with each other. PTSD symptoms were significantly and positively associated with combat exposure and negative mental health outcomes (depressive symptoms, anxiety symptoms, and hostility), and inversely associated with emotional well-being, and self-rated health. Conversely, significant relationships between total PTSD symptoms and eudaimonic well-being were not found in this sample. Overall, the current results demonstrate the psychometric adequacy of the PCL-5 translated in Korean. However, further research is needed to ascertain the relationships between PTSD symptoms and eudaimonic well-being among Korean Veterans.
