驻西沙官兵SCL-90测试结果的聚类分析

Subgrouping military personnel on Paracel Islands using SCL-90 and cluster analysis

目的 对驻西沙群岛官兵的心理健康状况进行聚类分析,从而可以有针对性进行心理干预.方法 采用90项症状清单（SCL-90）对驻西沙群岛174名军人进行测评,将其结果与军人常模及对照组比较并进行聚类分析.结果 驻岛官兵的人际敏感、恐怖及精神病性因子分[（1.65±0.56）分,（1.24±0.33）分,（1.44±0.46）分]低于中国军人常模（P＜0.05）;人际敏感因子分低于对照组（P＜0.05）,抑郁、焦虑因子分[（1.54±0.52）分,（1.46±0.47）分]与对照组比较差异无统计学意义（P＞0.05）,其余SCL-90因子分均高于对照组（P＜0.05）.经聚类分析,174名驻岛官兵可分为3类：第一类SCL-90得分较低,第二类得分中等,第三类得分较高.各类军人年龄、性别、婚恋状况、受教育程度、军龄、职别等人口学资料及服役相关情况差异有统计学意义（P＜0.05）.结论 驻西沙群岛官兵心理健康状况总体较好,可分为三个亚类,各类军人具有不同的人口学资料及服役相关特征.

Objective To identify distinct subgroups of military personnel from Paracel Islands based on mental status for providing basis to intervention measures.Methods 174 enlisted military personnel were interviewed by symptom checklist-90 （SCL-90）.The factor scores of SCL-90 were compared with army man norm and control group,then the cluster analysis was conducted.Results Interpersonal sensitivity,phobic and psychoticism of military personnel on Paracel Islands（（1.65±0.56）,（1.24±0.33）,（1.44±0.46）） scored lower than those of army man norm （P〈0.05）.Interpersonal sensitivity of military personnel on Paracel Islands scored lower than those of control （P〈0.05）,depression and anxiety of them had no difference to control （P〉0.05）,while other factors of them scored higher than control.According to cluster analysis,174 military personnel were divided into three subgroups.The first subgroup with high scores for all nine SCL-90-R dimensions,the second cluster showed moderate scores and the third cluster had lowest scores.Statistically significant sociodemographic differences could be found between the cluster groups （P〈0.05）.Conclusion The mental health status of military personnel stationed in Paracel Islands is good on the whole,and can be divided into three clusters with different demographic and service characteristics.
