目的分析驻海拔3970、4200、4330、4450米高度4个点共233名官兵心理健康状况及其特点。方法采用症状自评量表(SCL-90)对受试者进行测试,对测试结果进行统计学描述分析、聚类分析。结果 1受试者筛查阳性率为25.75%,各因子分值均值低于军人常模(χ2=6.41,P<0.05),10个因子按筛查阳性率数值大小依次排列为强迫症状>躯体化>敌对>人际关系敏感>其它>偏执>焦虑>抑郁>精神病性>恐怖;2快速聚类分析将研究对象分为3类,15(6.44%)人心理健康状况较差,55(23.60%)人心理处于亚健康状态,163(69.96%)人心理健康状况较好;3不同海拔高度阳性率有显著差异(χ2=20.96,P<0.05),总均分分值无显著差异(χ2=2.52,P>0.05),除人际关系敏感、焦虑、精神病性3个因子外,其他各因子均分值无显著差异(P>0.05)。结论高原军人心理健康状况总体阳性率比以往报道有显著降低,强迫症状、躯体化、敌对症状因子阳性率比较高。
Objective To analyze the mental health status of 233 officers and men and their characteristics at 4 points above sea level of 3970, 4200, 4330 and 4450 meters. Methods Subjects were tested using the Symptom Checklist 90 (SCL-90), and the results were statistically analyzed and clustered. Results 1 The positive rate of screening was 25.75%. The average score of each factor was lower than that of military norm (χ2 = 6.41, P <0.05). The 10 factors were ranked as obsessive-compulsive disorder (6.44%) had poor mental health status, 55 (23.60%) had poor mental health status, 15 (6.44%) had poor mental health status, (69.96%) had better mental health status; (3) There were significant differences in the positive rates at different altitudes (χ2 = 20.96, P <0.05), and there was no significant difference between the two groups (χ2 = 2.52, P> 0.05). Except interpersonal sensitivity, anxiety and psychosis, there were no significant differences among the other factors (P> 0.05). Conclusion The overall prevalence of mental health status of soldiers on the plateau is significantly lower than that reported in the past, and the prevalence of obsessive-compulsive symptoms, somatization, and hostile symptoms is relatively high.
