Objective To investigate the attentional bias of highly depressive soldiers to emotional wording with the emotion Stroop paradigm. Methods Three hundred and seventy-seven armed police soldiers completed the Symptom Checklist-90, State-Trait Anxiety Inventory and Center for Epidemiologic Studies Depression Scale (CES-D). After eliminating those with potential mental illness with SCL-90 total score over 160, positive project number over 43, and those with high trait of anxiety with TAI score over 50, 14 high depressive soldiers with CES-D score over 20 were selected to perform the emotional Stroop task based on Chinese Affective Words System. Finally, 1:1 matched case-control study was performed on 13 highly depressive soldiers and 13 mildly depressive soldiers matched for age, service length, education background and position. All the subjects were selected to finish the judgment of four blocks, including two positive blocks and two negative blocks. Results The accuracy difference and the reaction time difference in emotion blocks and emotion words between high depressive group and low depressive group were not significant (P>0.05). The reaction time of negative block was significantly longer than that of positive block in high depressive group (715.72±103.844 vs 639.42±104.101, t=2.573, P=0.024), There was no significant difference in the low depressive group (672.80±52.437 vs 669.23±62.836, t=0.435, P>0.05). Conclusions High depressive soldiers are not worse than low depressive soldiers in performance of emotional Stroop task. However, high depressive soldiers have attentional bias to negative words, while low depressive soldier have none. DOI: 10.11855/j.issn.0577-7402.2015.12.16 |
