To translate, cross-culturally adapt and test the reliability and validity of a Chinese version of the Infertility Self-Efficacy scale.
The Infertility Self-Efficacy (ISE) scale was translated into Chinese using forward and backward translations, expert consultation, cognitive interviews and a pilot study. To test the scale's reliability and validity, 515 infertile women in two hospitals were recruited to evaluate the Chinese version of the scale. Content validity was assessed by means of expert consultation. Exploratory factor and confirmatory factor analyses were performed using SPSS 26.0 and Amos 24.0. Reliability tests of the scale included Cronbach's alpha coefficient, split-half reliability and test-retest reliability.
The Chinese version of the ISE scale contains 16 items and one dimension. Content validity of the scale was 0.96. Results of exploratory factor analysis suggested that the one factor model was suitable for the scale, and factor loading of all items was greater than 0.4. Model fitting parameters of confirmatory factor analysis of the ISE scale were χ/df = 2.710, Root Mean Square Error Approximation (RMSEA) = 0.079, Standardized Root Mean Square Residual (SRMR) = 0.042, Comparative Fit Index (CFI) = 0.953, and Tucker-Lewis Index (TLI) = 0.939. Cronbach's alpha coefficient of the Chinese ISE was 0.980; split-half coefficient was 0.972 and retest reliability was 0.848 (P < 0.01).
The Chinese ISE scale is a reliable and valid instrument to evaluate the self-efficacy of infertile Chinese women.
翻译、跨文化调适并检验中文版不孕症自我效能量表的信效度。
采用正向和反向翻译、专家咨询、认知访谈及预试验，将不孕症自我效能量表（ISE）翻译成中文。为检验该量表的信效度，招募了两家医院的515名不孕女性对中文版量表进行评估。通过专家咨询评估内容效度。使用SPSS 26.0和Amos 24.0进行探索性因素分析和验证性因素分析。该量表的信度检验包括克朗巴哈α系数、分半信度和重测信度。
中文版ISE量表包含16个条目和1个维度。该量表的内容效度为0.96。探索性因素分析结果表明单因素模型适用于该量表，所有条目的因素负荷均大于0.4。ISE量表验证性因素分析的模型拟合参数为χ/df = 2.710，近似均方根误差（RMSEA）= 0.079，标准化均方根残差（SRMR）= 0.042，比较拟合指数（CFI）= 0.953，塔克 - 刘易斯指数（TLI）= 0.939。中文版ISE的克朗巴哈α系数为0.980；分半系数为0.972，重测信度为0.848（P < 0.01）。
中文版ISE量表是评估中国不孕女性自我效能的可靠且有效的工具。
