基于经典测量理论简化护士心理素质量表

Simplification of Mental Quality Inventory for nurses based on classical test theory

目的简化护士心理素质量表（MQIN）并评价其信效度。方法二次抽样武汉市5所三级甲等医院1067名在职护理人员问卷调查结果，利用离散趋势法、t检验法、相关系数法、因子分析法、Cronbach a系数法、专家法筛选条目形成简化版量表。利用Cronbacho α系数评价其内部一致性；利用各维度与量表的相关系数评价其内容效度，利用探索性因子分析评价其结构效度。结果简表（MQIN-72）包含5个维度，72个条目，累积方差贡献率为55．378％，Cronbachd系数为0．856，内容效度为0．599-0．903。结论简化版护士心理素质量表具有良好的信效度，能够作为我国护理人才选拔、培养及任用的简易筛查指标之一。

Objective To simplify the Mental Quality Inventory for Nurses （MQIN）, and evaluate its reliability and validity. Methods The second sampling to include the 1 067 nurses from 5 third-class hospitals were investigated to screen items using dispersion tendency, independent-samples t test, coefficient correlation, factor analysis, Cronbach α coefficient and expert consultation. The reliability was evaluated by Cronbach α coefficient, the correlation coefficient of each dimension with scale to evaluate its content validity, the exploratory factor analysis to evaluate its structural validity. Results The simplified scale （MQIN-72） includes 72 items belonging to 5 dimensions, and accounted for 55.378% of the accumulated variances. The Cronbach＇ s α coefficient was 0.856, the content validity index was between 0.599 and 0.903, Conclusions The simplified MQIN scale with excellent reliability and validity, this scale can be used as one of simple screening indexes for nurse＇ s selection, cultivation and engagement.
