Simplification of Mental Quality Inventory for nurses based on classical test theory / 中国实用护理杂志

ABSTRACT

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.
