To examine the reliability and validity of the Chinese version of nurses' self-concept questionnaire.
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.
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.
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).
This study verified the psychometric properties of the Chinese version of nurses' self-concept questionnaire.
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.
检验中文版护士自我概念问卷的信效度。
护士的自我概念对于缓解当前护士短缺的状况很重要。护士自我概念问卷是测量护士对专业能力自我认知的有效工具。然而，中文版的心理测量特性尚未得到检验。
本研究采用两阶段研究设计。在第一阶段，招募了347名注册护士来确定中文版的心理测量特性。在第二阶段，使用验证性因素分析，以1017名受访者为样本，检验从第一阶段提取的因素结构。
中文版的内部一致性为0.95，重测信度为0.83。探索性因素分析提取了六个维度。第二阶段的结果显示模型拟合度和区分效度可接受。中文版是马氏职业倦怠量表的显著预测因子（β = -0.58；P = 0.00）。
本研究验证了中文版护士自我概念问卷的心理测量特性。
中文版护士自我概念问卷将有助于评估护士的专业自我概念，并有助于制定个性化的自我概念策略。
