目的检验军人精神疾病预测量表的信度及效度。方法采取随机整群抽样法抽取1 477名官兵,以军人精神疾病预测量表进行测评,并对其中120名官兵同时测量中国军人心理健康量表(CMMHS)。利用统计软件对结果进行分析,考察量表的信度及效度。结果总量表的Cronbach’sα系数为0.784,分量表为0.705~0.854(P<0.01);总量表的分半信度为0.914,分量表为0.754~0.934(P<0.01)。各因子间相关系数为0.512~0.948,各因子与总量表的相关系数为0.673~0.961(P<0.01)。维量分析表明各维度间有较好的区分度。探索性因素分析结果显示,此研究结果与原量表各条目的因子归类一致。验证性因素分析发现模型拟合程度较高。该量表校标效度较高。结论军人精神疾病预测量表信度、效度较好,符合心理测量学标准,可作为军人精神疾病预测的有效工具。
Objective To test the reliability and validity of the mental illness prediction scale of military personnel. Methods A total of 1 477 officers and men were sampled by random cluster sampling method and evaluated by Mental Disorders Prediction Scale. 120 officers and men simultaneously measured the Chinese Mental Health Scale (CMMHS). The use of statistical software to analyze the results to examine the scale of reliability and validity. Results The Cronbach’s α coefficient of the total scale was 0.784, and the subscales ranged from 0.705 to 0.854 (P <0.01). The half-reliability of the total scale was 0.914, and the subscale was 0.754-0.934 (P <0.01). The correlation coefficient of each factor was 0.512 ~ 0.948, the correlation coefficient between each factor and the total scale was 0.673 ~ 0.961 (P <0.01). Dimensional analysis shows that there is a good degree of discrimination between the various dimensions. Exploratory factor analysis showed that the results of this study were consistent with those of the original scale. Confirmatory factor analysis found that the model fitted to a higher degree. The scale calibration validity. Conclusion The military mental illness prediction scale has good reliability and validity, meets the standards of psychometrics and can be used as an effective tool for the prediction of military mental diseases.
