Abstract

Objective: Excessive gestational weight gain, driven by the global raise in obesity, poses significant health risks for both mothers and infants. This study aimed to validate and assess the reliability of the Korean version of the self-efficacy scale for healthy eating and physical activity to support pregnancy-related weight management research in Korea.

Methods: This study is a secondary data analysis using previously collected data from an online survey of pregnant women in South Korea. The self-efficacy scale underwent linguistic validation, including translation, back-translation, and expert review. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to assess content and construct validity, along with internal consistency reliability testing.

Results: A total of 369 pregnant women participated, primarily in their 30s (85.1%) and college-educated (79.1%). Content validity was high, with a scale-level content validity index of 0.99. Construct validity was confirmed through EFA and CFA, with the final model achieving satisfactory fit indices (χ2/df = 2.19, CFI = 0.90, TLI = 0.89, SRMR = 0.07, RMSEA = 0.06). The scale demonstrated high reliability, with Cronbach's alpha values of 0.93 for both subscales.

Conclusion: The validated Korean self-efficacy scale is a reliable tool for assessing pregnancy-related weight management behaviors. This culturally adapted instrument can support research and interventions promoting healthy eating and physical activity among Korean pregnant women.

韩国版孕妇健康饮食与身体活动自我效能量表的效度与信度。
目的:在全球肥胖增加的推动下,妊娠期体重过度增加对母亲和婴儿都构成了重大的健康风险。本研究旨在验证和评估韩国版健康饮食和身体活动自我效能量表的可靠性,以支持韩国怀孕相关体重管理研究。方法:本研究是利用先前收集的韩国孕妇在线调查数据进行二次数据分析。自我效能量表进行了语言验证,包括翻译、反翻译和专家评审。采用探索性因子分析(EFA)和验证性因子分析(CFA)评估内容和结构效度,并进行内部一致性信度检验。结果:共有369名孕妇参与,主要是30多岁(85.1%)和大学学历(79.1%)。内容效度高,量表水平内容效度指数为0.99。通过EFA和CFA验证结构效度,最终模型达到满意的拟合指标(χ2/df = 2.19, CFI = 0.90, TLI = 0.89, SRMR = 0.07, RMSEA = 0.06)。量表具有较高的信度,两个分量表的Cronbach's alpha值均为0.93。结论:经验证的韩国自我效能感量表是评估妊娠相关体重管理行为的可靠工具。这一适应文化的工具可以支持促进韩国孕妇健康饮食和体育活动的研究和干预措施。
