To validate a blended health belief model and integrated behavioral model of selected modifiable psychosocial constructs during pregnancy to seek the best-fit path model for breastfeeding intention.
A nonexperimental, cross-sectional study.
A virtual online market research sample aggregator.
Women (N = 300) between 18 and 45 years of age in their second or third trimesters of pregnancy participated in the study in February 2018.
Based on the health belief model and the integrated behavioral model, we proposed a theoretical framework, including self-efficacy for breastfeeding, knowledge, perceived benefits, perceived barriers, attitude toward breastfeeding, patient-provider interaction, and motivation to breastfeed, to predict breastfeeding intention. We administered a 98-item questionnaire modified from preexisting instruments. We conducted descriptive, bivariate, and regression analyses to help with the formation of the path model.
The best-fit path model with all significant paths and effect directions showed that intention to breastfeed is directly influenced by motivation to breastfeed, attitudes toward breastfeeding, and self-efficacy for breastfeeding, which together accounted for 56% (R) of the variance in intention. We also identified indirect effects from knowledge about breastfeeding, patient-provider interaction, perceived benefits, and perceived barriers and their interrelationships with effect directions.
Through our findings, we contribute to the emerging body of evidence that shows the significant variables and their effect directions for breastfeeding intention. Incorporating these findings may provide support and evidence for clinical and community interventions focusing on modifiable psychosocial constructs during pregnancy to promote breastfeeding and further investigations using health behavior theories.
验证一个混合健康信念模型和选定可改变的心理社会结构的综合行为模型，以寻找最佳拟合路径模型，用于母乳喂养意向。
非实验性、横断面研究。
虚拟在线市场研究样本聚合器。
年龄在 18 至 45 岁之间，处于妊娠第二或第三阶段的 300 名女性参加了 2018 年 2 月的研究。
基于健康信念模型和综合行为模型，我们提出了一个理论框架，包括母乳喂养自我效能、知识、感知益处、感知障碍、母乳喂养态度、医患互动和母乳喂养动机，以预测母乳喂养意向。我们使用了一个由预先存在的工具修改的 98 项问卷。我们进行了描述性、双变量和回归分析，以帮助形成路径模型。
具有所有显著路径和方向的最佳拟合路径模型表明，母乳喂养意向直接受到母乳喂养动机、母乳喂养态度和母乳喂养自我效能的影响，这三者共同解释了 56%（R）的意向变异。我们还确定了来自母乳喂养知识、医患互动、感知益处和感知障碍的间接影响，以及它们之间的相互关系和方向。
通过我们的发现，我们为新兴的证据体系做出了贡献，该体系展示了母乳喂养意向的重要变量及其方向。纳入这些发现可能为关注妊娠期间可改变的心理社会结构的临床和社区干预措施提供支持和证据，以促进母乳喂养，并进一步使用健康行为理论进行调查。
