Nursing support and control during birth are both crucial factors influencing whether a woman has a satisfying birth experience. Yen indicated that there is a significant correlation between a woman’s sense of control during birth and pain relief during labor. Yen suggested that an inconsistency between a pregnant woman’s expectation of control during birth and her experience may lower her satisfaction with the birth experience. Activities to support a pregnant woman during labor provided by nursing personnel can increase a pregnant woman’s adaptive capacity, enabling her to have positive and satisfying birth experience. In this study, the English version of the Support and Control in Birth Scale (SCIB) was translated into Chinese by adopting the Brislin's translation model revised by Jones et al. (2001). The researcher tested the reliability and validity of this Chinese version of the SCIB. We surveyed 282 women undergoing natural childbirth using a questionnaire within 48 hours after giving birth. The content of the Chinese version of the SCIB was implemented clinically after its expert validity and content validity were tested. The reliability was tested for internal consistency and reliability using Cronbach's α and test-retest reliability; the validity was tested through criterion-related validity (predictive validity and concurrent validity) and construct validity. The results were as follows: 1. Construct validity of the Chinese version of the SCIB was tested using confirmatory factor analysis (CFA). The analysis result showed that the overall goodness-of-fit did not reach the standard but the parsimonious fit was attained. 2. Reliability of the Chinese version of the SCIB was .81; its test-retest reliability was .96. 3. Criterion-related validity of the Chinese version of the SCIB was tested through a scale of women's views on birth experience. The test results showed that there was a significant correlation between the Chinese version of the SCIB and the scale of women's views on birth experience (r = .31, p < .01). There was a low correlation between the scale of women's views on birth experience and all aspects of the Chinese version of the SCIB, including internal control (r = .15, p < .05), external control (r = .30, p < .01), and support (r = .21, p < .01). Concurrent validity of the Chinese version of the SCIB was tested through the Bryanton Adaptation of the Nursing Supporting Labor Questionnaire (BANSILQ) and the control in birth scale. The test results showed that there was a moderate correlation between the BANSILQ and the support aspect (r = .50, p < .01); the control in birth scale had a low to moderate correlation between the aspects of internal control (r = .44, p < .01) and external control (r =.30, p < .01). The results of this study could be used for future research based on the Chinese version of the SCIB with good reliability and validity. This study investigated subjects from only one institution; therefore, the results may not be generalizable. However, the number of cases in this study was large enough that reliability and validity of this study were statistically significant. Furthermore, during the data collection process, each subject was required to fill out four questionnaires; therefore, there were some situations which may influence the correctness of the results. For instance, a number of subjects refused to fill out questionnaires, omitted certain questionnaires, or chose the same option for each question. Future researchers will need to cautious when referring to the results of this study.
