Cross-cultural adaptation of The Postpartum Childcare Stress Checklist into Brazilian Portuguese

Abstract Objectives: to carry out the cross-cultural adaptation of The Postpartum Childcare Stress Checklist scale to be used in Brazil. Methods: the cross-cultural adaptation process followed internationally defined guidelines: double translation, synthesis and back-translation, analysis by a committee of experts, proposal for a pre-final and pre-test version, analysis of the psychometrics properties and generation of the final version. The reliability and validity of the final version were analyzed through a cross-sectional epidemiological study involving 190 women in the postpartum period. Cronbach’s α indicator for reliability analysis and exploratory factor analysis with main component extraction were estimated for validity analysis. Results: α-Cronbach’s was 0.894. The tested Brazilian version proved to be one-dimensional and the factor analysis pointed to four factors that were very closely distributed and explained 57.8% of the variance. All items of the original instrument were maintained in the proposed final version. Conclusions: the proposed Brazilian version proved to be valid and reliable for application in Brazilian populations.

【摘要】
研究目的：对《产后育儿压力检查表（Postpartum Childcare Stress Checklist）》进行跨文化调适，以适配巴西人群使用。
研究方法：本次跨文化调适流程遵循国际通用规范，具体包括双向翻译、文本合成与回译、专家委员会审议、拟定预终稿并开展预试验、分析量表心理测量学特性并生成终版量表。本研究通过纳入190名产后女性的横断面流行病学研究（cross-sectional epidemiological study），对终版量表的信效度进行检验。信度分析采用克朗巴赫α系数（Cronbach’s α），效度分析则采用以主成分提取法（main component extraction）开展的探索性因子分析（exploratory factor analysis）。
研究结果：克朗巴赫α系数为0.894。经检验的巴西版量表被证实为单维结构，因子分析结果显示其包含四个分布紧密相关的因子，累计解释方差变异达57.8%。原量表所有条目均完整保留于本次提出的终版量表中。
研究结论：本次研发的巴西版产后育儿压力检查表具备良好的信效度，可有效应用于巴西人群的相关研究与实践。
