Abstract

Objective

This study was conducted to test the validity and reliability of the Turkish version of the Comprehensive Breastfeeding Knowledge Scale.

Method

This methodological study was carried out between July 1, 2023, and May 1, 2024, in the Department of Obstetrics and Gynecology at a university hospital. Approvals were obtained from the original scale author, the ethics committee, the institution where data were collected, and the participants. The study sample comprised 350 participants, including 200 primiparous pregnant women and 150 postpartum women. For validity, the Content Validity Ratio (CVR) and Content Validity Index (CVI) were used to assess language and content validity, and Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to evaluate construct validity. For reliability, item analyses were conducted, and the Intraclass Correlation Coefficient (ICC) and Paired t-Test were used to determine test-retest reliability, while Cronbach’s alpha coefficient was employed to assess internal consistency.

Results

Of the women who participated in the study, 57.1 % were pregnant and 42.9 % were in the postpartum period. Among the participants, 39.7 % were between the ages of 18 and 25, 38.9 % were high school graduates, and 51.4 % had received breastfeeding education. EFA results revealed that the scale maintained a three-factor structure consistent with the original scale, the items were distributed across the factors in a similar manner, factor loadings ranged from 0.50 to 0.65, and the explained variance was 37.3 %. The CFA results indicated excellent model fit with a chi-square/df ratio of 1.912, and good fit indices, including GFI (0.904), RMSEA (0.051), and CFI (0.894).

Conclusion

The findings of this study demonstrate that the Turkish version of the Comprehensive Breastfeeding Knowledge Scale is a valid and reliable measurement tool for assessing breastfeeding knowledge among primiparous pregnant and postpartum women. The scale can be utilized in descriptive studies evaluating breastfeeding knowledge and in experimental studies aimed at improving breastfeeding knowledge, as a pre-test and post-test assessment tool.

土耳其语版母乳喂养综合知识量表的效度和信度调查。

目的：本研究对土耳其版母乳喂养综合知识量表的效度和信度进行检验。方法：本方法学研究于2023年7月1日至2024年5月1日在某大学附属医院妇产科进行。获得原始量表作者、伦理委员会、数据收集机构和参与者的批准。研究样本包括350名参与者，其中包括200名初产妇和150名产后妇女。效度方面，采用内容效度比（CVR）和内容效度指数（CVI）评估语言和内容效度，采用探索性因子分析（EFA）和验证性因子分析（CFA）评估构念效度。信度采用项目分析，采用类内相关系数（Intraclass Correlation Coefficient， ICC）和配对t检验确定重测信度，采用Cronbach’s alpha系数评估内部一致性。结果：参与研究的妇女中，57.1%为孕妇，42.9%为产后。在参与者中，39.7%的人年龄在18 - 25岁之间，38.9%的人高中毕业，51.4%的人接受过母乳喂养教育。结果表明，该量表与原量表保持一致的三因子结构，各因子之间的分布基本一致，因子负荷范围为0.50 ~ 0.65，解释方差为37.3%。CFA结果表明，模型拟合良好，卡方/df比为1.912，拟合指数良好，包括GFI（0.904）、RMSEA（0.051）和CFI（0.894）。结论：本研究结果表明，土耳其版母乳喂养综合知识量表是评估初产妇和产后妇女母乳喂养知识的有效和可靠的测量工具。该量表可用于评价母乳喂养知识的描述性研究和旨在提高母乳喂养知识的实验性研究，作为测试前和测试后的评估工具。
