摘要目的 了解心理特质在军事应激中与应激反应生理指标的差异,从而评估不同心理特质军人应激反应发生率.方法 在突然紧急连续机械化拉动训练第15天时,对372人进行状态-特质焦虑问卷、血压、呼吸、脉搏、血乳酸及血皮质醇(08:00am-09:00am)测定,其结果 分别与常模、正常值比较.结果 特质焦虑值高于常模2个标准差(高特质焦虑)占26.1%(97/372),特质焦虑值低于常模2个标准差(低特质焦虑者)占21.2%(79/372).状态焦虑值高于常模2个标准差的占总人数的46.0%(172/372).状态焦虑、血皮质醇、血乳酸及收缩压(四联症)同时变化显著者132人(P＜0.01),舒张压变化不明显.高特质焦虑者发生"四联症"占62.9%(61/97);非高特质焦虑者发生"四联症",占25.9%(71/275),其中低特质焦虑者发生"四联症"占15.2%(12/79).结论 突然紧急连续机械化拉动训练是一种心理与生理复合性高应激军事活动,高特质焦虑军人的强应激反应发生率高于非高特质焦虑军人,不同心理特质者对军事应激引起的生理心理反应有明显差异,因此,心理特质可以考虑作为预测应激反应类型的参考指标之一.

abstractsObjective To understand the difference between psychological characteristics and stress response as a result of military stress and to evaluate the rate of stress response among individuals with different psychological characteristics.Methods The State-Trait Anxiety Inventory,blood pressure,breath,pulse wave,and serum levels of lactate acid and cortisol were measured at 8 to 9 am for 372 servicemen following 15 days'training.Results In 97 subjects ,the value of special characteristic anxiety Was 2-standard deviation higher than normal model(i.e.high special characteristic anxiety).and low special characteristic anxiety was found in 79.The condition anxiety of 2 standard deviation higher than normal model wag found in 172 participants.A total of 132 subjects showed significant changes in condition anxiety,serum cortisol and lactic acid,and systolic blood pressure(P＜0.01).Sixty-one or 71 subjects with high or low special characteristic anxiety experienced condition anxiety,changed serum cortisol and lactic acid,and systolic blood pressure,respectively.Conclusion Psychological characteristics may be considered as a predicting factor of stress response.
