Converging evidence reveals significant increase in both state anxiety and trait anxiety during the past 2 decades among military servicemen and servicewomen in China. In the present study, we employed the Chinese version of the State-trait Anxiety Inventory (STAI) to examine trait and state anxiety in Chinese military servicemen and servicewomen. We further evaluated orienting, alerting and execution inhibition using the attention network test.Healthy military servicemen and servicewomen were recruited for the present study. The STAI was used to measure both state and trait anxiety and the attention network test was done to determine reaction time and accuracy rate.Fifty-seven subjects were eligible for the study. Their mean STAI score was 3.2 ± 2.8 (range, 1-17) and 29 (50.9%) subjects were categorized into the high trait anxiety group and 28 (49.1%) subjects into the low trait anxiety group. The reaction time of the high trait anxiety group to incongruent, congruent, and neutral target was significantly longer than that of the low trait anxiety group (P < .05). Moreover, the accurate rate of the high trait anxiety group for incongruent, congruent, and neutral target was significantly higher than that of the low trait anxiety group (P < .05). Repeated analysis of variance showed marked effect of trait anxiety, cue types, and target types on reaction time. There was significant interaction among trait anxiety, target types, and cue types. Trait anxiety and target types also had marked effect on the accurate rate. Multivariate analysis showed no marked effect of trait anxiety on the alerting, orienting, and execution inhibition subnetwork.The present study has demonstrated that military service personnel with high trait anxiety requires more time for cognitive processing of external information but exhibits enhanced reaction accuracy rate compared to those with low trait anxiety. Our findings indicate that interventional strategies to improve the psychological wellbeing of military service personnel should be implemented to improve combat mission performance.
越来越多的证据表明，在过去20年中，中国军人的状态焦虑和特质焦虑均显著增加。在本研究中，我们采用中文版的状态-特质焦虑量表（STAI）来检测中国军人的特质焦虑和状态焦虑。我们还使用注意力网络测试进一步评估了定向、警觉和执行抑制功能。本研究招募了健康的军人。使用STAI测量状态焦虑和特质焦虑，并通过注意力网络测试来确定反应时间和准确率。57名受试者符合研究条件。他们的STAI平均得分为3.2±2.8（范围为1-17），29名（50.9%）受试者被归类为高特质焦虑组，28名（49.1%）受试者被归类为低特质焦虑组。高特质焦虑组对不一致、一致和中性目标的反应时间显著长于低特质焦虑组（P<0.05）。此外，高特质焦虑组对不一致、一致和中性目标的准确率显著高于低特质焦虑组（P<0.05）。重复方差分析显示特质焦虑、线索类型和目标类型对反应时间有显著影响。特质焦虑、目标类型和线索类型之间存在显著交互作用。特质焦虑和目标类型对准确率也有显著影响。多变量分析显示特质焦虑对警觉、定向和执行抑制子网络没有显著影响。本研究表明，与低特质焦虑的军人相比，高特质焦虑的军人在处理外部信息时需要更多时间进行认知加工，但反应准确率更高。我们的研究结果表明，应实施干预策略来改善军人的心理健康，以提高作战任务表现。
