Compared with the control group, the battle group showed significantly higher scores on the subscales of obsessive-compulsive symptom, interpersonal sensitivity, depression, anxiety, phobic anxiety, and paranoid ideation (t=2.323, 3.250, 3.158, 2.712, 2.391, and 2.137, all P<0.05) , as well as significantly higher total score, number of positive items, and average score of positive symptoms (t=4.128, 4.357, and 4.632, all P<0.05). In the battle group, the scores on the subscales of somatization, obsessive-compulsive symptom, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism, and additional items, total score, number of positive items, and average score of positive symptoms were significantly lower than the military reference values (t=4.364, 5.127, 5.280, 3.783, 7.012, 5.361, 4.369, 6.167, 6.476, 3.558, 6.357, 4.379, and 6.763, all P<0.05).
