军人心理承受力量表的信度效度检验

Reliability and validity of the mental resilience scale for military personnel

目的研制中国军人心理承受力量表,检验量表的信度和效度。方法随机整群抽取健康男性官兵2611人,分为A组(n=1112)、B组(n=1499)。用自制《军人心理承受力量表》分别对两组进行测试。对A组数据进行探索性因素分析和相关分析;对B组数据进行验证性因素分析。结果经探索性因素分析和相关分析发现,总量表的Cronbach'α系数为0.833,各分量表为0.535～0.880。总量表分半信度系数为0.787,各分量表为0.339～0.611。总量表重测信度系数为0.401,各分量表为0.302～0.668。量表总分与各因子的相关系数为0.445～0.786(P<0.01),各因子之间的相关系数为0.110～0.679(P<0.01)。经验证性因素分析发现,数据与假设的5因子模型(意志力、家庭支持、自信、问题解决和人际交往)拟合程度较高,拟合指标的χ2值为1663.997,近似均方根差为0.054,残差均方根值为0.021,塔克-刘易斯指数、比较拟合指数、增值拟合指数、拟合优度指数分别0.921、0.931、0.931、0.922。结论自行编制的军人心理承受力量表具有良好的信度和效度,可在部队推广使用。

Objective To develop a mental resilience scale for military personnel and examine the reliability and validity of this scale.MethodsA total of 2611 male officers and soldiers chosen by random cluster sampling to outline the mental resilience scale for military personnel,with the subjects divided into group A and group B.In group A （n=1112） exploratory factor analysis and correlation analysis were used,and in group B （n=1499） confirmatory factor analysis was used.ResultsThe results of exploratory factor analysis and correlation analysis indicated that the Cronbach＇α coefficient of total scale was 0.833,and that of subscales was 0.535-0.880;split-half reliability coefficient of total scale was 0.787,and that of subscales 0.339-0.611;retest-reliability coefficient of total scale was 0.401,and that of subscales 0.302-0.668.The correlation coefficients of total scale scores and each factor were 0.445-0.786 （P0.01）,and the correlation coefficients ranged from 0.110 to 0.679 between the factors （P0.01）.According to the results of confirmatory factor analysis,the sample data fitted better to the hypothesized structure of five factors （willpower,family support,self-confidence,problem solving and interpersonal communication）,and the indexes of Chi-Square,root mean square error of approximation （RMSEA）,root mean square residual （RMR）,Tucker-Lewis index （TLI）,comparative fit index （CFI）,incremental fit index （IFI） and goodness of fit index （GFI） were 1663.997,0.054,0.021,0.921,0.931,0.931 and 0.922,respectively.ConclusionThe mental resilience scale for military personnel has good reliability and validity and can be extensively applied to the militaries.
