Children's intake of discretionary choices is excessive. This study aimed to develop a questionnaire measuring parents' attitudes and beliefs towards limiting provision of discretionary choices, using the Health Action Process Approach model.
The questionnaire items were informed by the Health Action Process Approach model, which extends the Theory of Planned Behaviour to include both motivational (intention) and volitional (post-intention) factors that influence behaviour change. The questionnaire was piloted for content and face validity (expert panel, n = 5; parents, n = 4). Construct and predictive validity were examined in a sample of 178 parents of 4-7-year-old children who completed the questionnaire online. Statistical analyses included exploratory factor analyses, Cronbach's alpha and multiple linear regression.
Pilot testing supported content and face validity. Principal component analyses identified constructs that aligned with the eight constructs of the Health Action Process Approach model. Internal consistencies were high for all subscales, in both the motivational (Cronbach's alpha 0.77-0.88) and volitional phase (Cronbach's alpha 0.85-0.92).
Initial results from validation tests support the development of a new questionnaire for measuring parent attitudes and beliefs regarding provision of discretionary choices to their 4-7-year-old children within the home. This new questionnaire can be used to gain greater insight into parents' attitudes and beliefs that influence ability to limit discretionary choices provision to children. Further research to expand understanding of the questionnaires' psychometric properties would be valuable, including confirmatory factor analysis and reproducibility.
儿童对可自由选择食物的摄入量过高。本研究旨在使用健康行动过程方法模型，开发一种测量父母对限制提供可自由选择食物的态度和信念的问卷。
问卷项目来源于健康行动过程方法模型，该模型扩展了计划行为理论，纳入了影响行为改变的动机（意图）和意志（意图后）因素。该问卷在内容和表面效度方面进行了试点研究（专家小组，n=5；父母，n=4）。在一个由 178 名 4-7 岁儿童父母组成的样本中，通过在线方式完成问卷，对其进行了结构和预测效度检验。统计分析包括探索性因素分析、克朗巴赫α系数和多元线性回归。
试点测试支持内容和表面效度。主成分分析确定了与健康行动过程方法模型的八个结构相一致的结构。在动机（克朗巴赫α系数 0.77-0.88）和意志阶段（克朗巴赫α系数 0.85-0.92），所有子量表的内部一致性都很高。
验证测试的初步结果支持开发一种新的问卷，用于测量父母在家庭中为 4-7 岁儿童提供可自由选择食物的态度和信念。该新问卷可用于更深入了解影响限制儿童提供可自由选择食物能力的父母态度和信念。进一步研究扩大对问卷心理测量特性的理解将是有价值的，包括验证性因素分析和可重复性。
