Development of Patient Safety Nurse Competency Evaluation Scale and its reliability and validity test

Abstract

Objective To develop a Patient Safety Nurse Competency Evaluation Scale, and evaluate its reliability and validity. Methods The Patient Safety Nurse Competency Evaluation Scale was developed through literature review, semi-constructed interview and experts consultation. A total of 590 nurses in 5 Class ⅢGrade A hospitals in Beijing were selected by convenient sampling methods and investigated by self-evaluation and peer evaluation. Results The final instrument included 35 items, organized into 6 composites by exploratory factor analysis, with the cumulative contribution of 65.983%. The factor analysis confirmatory showed that χ2/df was 2.742, and RMSEA was 0.064. Correlation coefficients between composites and total scale ranged from 0.694 to 0.812, and correlation coefficients between composites ranged from 0.367 to 0.647, with statistical significance (P<0.05) . The content validity index (S-CVI) was 0.933. The total scale internal consistency reliability was 0.942. The retest reliability coefficient of the general scale was 0.832. The correlation coefficients between self-evaluation and peer evaluation ranged from 0.342 to 0.517 in medium correlation. Conclusions The Patient Safety Nurse Competency Evaluation Scale demonstrates adequate reliability and validity. It is culturally appropriate for nurses self-evaluation and peer evaluation on patient safety competency.
