Note. N ranges from 259-292. Because Officer/Enlisted status was dichotomously scored (1/0), mean values indicate the proportion of the sample endorsing being an officer. Captivity duration was assessed in months. All pairwise comparisons are significant at the p < .01 level based on Scheffe’s test.
