(2013) Journal of Nursing Management 21 , 657–667 The reliability and validity of the Chinese version of nurses’ self‐concept questionnaire Aim To examine the reliability and validity of the Chinese version of nurses’ self‐concept questionnaire. Background Nurses’ self‐concept is important to alleviate the current shortage of nurses. Nurses’ self‐concept questionnaire is an effective instrument to measure nurses’ self‐perception of professional competencies. However, the psychometric properties of the Chinese version have not been tested. Methods A two‐stage research design was used in this study. At Stage 1347 registered nurses were recruited to establish the psychometric properties of the Chinese version. At Stage 2, a confirmatory factor analysis was used to examine the extracted factor structure from Stage 1 with 1017 respondents as a sample. Results The internal consistency of the Chinese version was 0.95 and the test–retest reliability was 0.83. The exploratory factor analysis extracted six dimensions. The findings at Stage 2 showed an acceptable model fit and discriminant validity. The Chinese version was a significant predictor of Maslach Burnout Inventory (β = −0.58; P = 0.00). Conclusions This study verified the psychometric properties of the Chinese version of nurses’ self‐concept questionnaire. Implication for nursing management The Chinese version of nurses’ self‐concept questionnaire will facilitate the evaluation of professional self‐concept among nurses and help to develop the individualized self‐concept strategies.
