Cross-cultural adaptation and psychometric evaluation of the Brazilian Portuguese version of the childbirth experience questionnaire

Abstract

Background: The Childbirth Experience Questionnaire (CEQ) is a tool designed to assess women's perceptions about labor and delivery. The aim of this study was to perform the cross-cultural adaptation and validation of the Brazilian Portuguese version of the CEQ (CEQ-Br). Methods: The original version of the CEQ was translated into Portuguese, analyzed by a committee of experts, back translated, and finally submitted to pilot-test. Two applications of the CEQ-Br were performed along with the quality of life questionnaire Medical Outcomes Study 36 - Item Short-Form Health Survey (SF-36). The SPSS software was used for statistical analysis, the intraclass correlation coefficient was used to investigate test-retest reliability, the internal consistency was investigated with the Cronbach's Alpha, and the construct validity was investigated via the Spearman correlation test. The level of significance was set at 5%. Results: The study included 308 women with a mean age of 31.1 ± 8.7 years. The internal consistency results for the total CEQ-Br score was considered adequate (0.89), the test-retest showed a substantial result with an ICC of 0.90, and the construct validity was analyzed via the Spearman correlation between all SF-36 dimensions and the total CEQ-B score, the analyses were considered adequate. Conclusions: The results presented in this CEQ-Br validation study showed that the instrument was reliable in measuring the established psychometric properties and was considered valid. Therefore, the CEQ-Br can be applied to the Brazilian population.
