This study aims to propose and evaluate a theory-driven questionnaire addressing barriers to healthy eating among mothers of young children.
Statements drawing upon the Social Cognitive Theory were developed/gathered based on literature review and previous qualitative research. Part I (43 items) included general barriers, attitudes to nutrition advice and outcome expectations. Part II (9 items) included subjective knowledge and general self-efficacy scales. An online survey was undertaken with 267 Danish women. The validation process included content and face validity, exploratory factor analysis (EFA) and reliability analysis. Confirmatory factor analysis (CFA) tested possible associations between the constructs and potential health outcomes (BMI and healthiness of eating habits).
The EFA supported an adequate factorial validity with a 5-factor, 37-item structure model for Part I, and a high internal reliability of Parts I and II (Cronbach's alpha > 0.7). The CFA revealed an association between certain constructs and perceived healthiness of eating and BMI. Results support the reliability and factorial validity of the social cognitive measures assessing barriers to healthy eating among mothers.
These promising findings of reliability and initial validity suggest that researchers and practitioners interested in identifying women who face difficulties in the family food environment may find the scales useful. We propose a short version of the questionnaire for health practitioners.
本研究旨在提出并评估一个理论驱动的问卷，以确定幼儿母亲健康饮食的障碍因素。
基于文献回顾和先前的定性研究，提出了（汲取了社会认知理论的）观点的陈述。第一部分（43 个项目）包括一般障碍、对营养建议的态度和结果预期。第二部分（9 个项目）包括主观知识和一般自我效能感量表。一项针对 267 名丹麦女性的在线调查。验证过程包括内容和表面有效性、探索性因素分析（EFA）和可靠性分析。验证性因素分析（CFA）测试了结构之间的潜在关联和潜在的健康结果（BMI 和饮食习惯的健康程度）。
EFA 支持了一个充分的因子有效性，第一部分的 5 因子、37 个项目结构模型，以及第一部分和第二部分的高内部可靠性（Cronbach's alpha > 0.7）。CFA 揭示了某些结构与感知的饮食健康和 BMI 之间的关联。研究结果支持了用于评估母亲健康饮食障碍的社会认知措施的可靠性和因子有效性。
这些可靠性和初步有效性的有希望的发现表明，有兴趣确定在家庭食物环境中面临困难的女性的研究人员和从业者可能会发现这些量表有用。我们为健康从业者提出了问卷的简短版本。
