BACKGROUND
The Support and Control in Birth (SCIB) scale primarily measures the perceived support and control of expectant mothers during childbirth, thereby obtaining an understanding of their birth experiences. The advantages of this scale are its good reliability and validity and that it consolidates birth support and control. However, a Chinese version of the scale has yet to be developed. Therefore, this study sought to evaluate the validity and reliability of a Chinese version of the Support and Control in Birth Scale (C-SCIB).
METHODS
A total of 228 postpartum women participated in this study. The C-SCIB scale was developed through a translation and back translation, followed by an evaluation of its content validity by a group of experts. Cronbach's α internal consistency and test-retest reliability were used to test the reliability of the scale. In addition, criterion-related validity (predictive validity and concurrent validity) and construct validity were used to test the validity of the scale.
RESULTS
The C-SCIB scale showed good results in terms of the item-level and scale-level content validity indices. The Cronbach's α internal consistency was 0.81, and its test-retest reliability was 0.96. The confirmatory factor analysis results showed the overall goodness-of-fit was parsimony fit indices. The predictive validity analysis showed a significant positive correlation between the C-SCIB scale and the Questionnaire Measuring Attitudes About Labor and Delivery (r = 0.31, p < 0.01). Furthermore, the concurrent validity analysis showed a significant and moderate correlation between the C-SCIB and the Bryanton Adaptation of the Nursing Support in Labor Questionnaire (r = 0.49, p < 0.01) as well as the Labor Agentry Scale (r = 0.51, p < 0.01).
CONCLUSION
The C-SCIB scale was proven to have good reliability and validity, and thus can be used to measure the degree of support and the locus of control perceived by expectant women during labor.
背景
支持和控制分娩量表（SCIB）主要测量产妇在分娩过程中感知到的支持和控制程度，从而了解她们的分娩体验。该量表的优点是信度和效度良好，并且整合了分娩支持和控制。然而，该量表尚未开发中文版本。因此，本研究旨在评估支持和控制分娩量表中文版（C-SCIB）的效度和信度。
方法
共有 228 名产后妇女参与了本研究。通过翻译和回译的方式开发了 C-SCIB 量表，然后由一组专家评估其内容效度。采用 Cronbach's α 内部一致性和重测信度来检验量表的信度。此外，采用效标关联效度（预测效度和同时效度）和结构效度来检验量表的效度。
结果
C-SCIB 量表在项目水平和量表水平的内容效度指标上表现良好。Cronbach's α 内部一致性为 0.81，重测信度为 0.96。验证性因子分析结果表明，整体拟合度是简约拟合指数。预测效度分析表明，C-SCIB 量表与分娩态度问卷（r=0.31，p<0.01）之间呈显著正相关。此外，同时效度分析表明，C-SCIB 与布赖顿分娩护理支持适应量表（r=0.49，p<0.01）和分娩代理权量表（r=0.51，p<0.01）之间呈显著中度相关。
结论
C-SCIB 量表具有良好的信度和效度，可用于测量产妇在分娩过程中感知到的支持程度和控制程度。
