Social cognitive models suggest a crucial role played by perceived barriers in promoting healthy behaviors, including healthy eating. We aimed to develop a new questionnaire to assess parental perceived barriers to healthy feeding in young children and perform the instrument's preliminary psychometric evaluation. The initial pool of items was developed based on reviews and qualitative studies. First, we conducted an online, descriptive, cross-sectional study with 278 parents of 2-6-year-old children to examine its factorial structure and internal consistency. Then, a second study with 168 parents from a similar population assessed convergent/discriminant and known-groups validity. The exploratory factorial analysis confirmed the scale's theoretical structure. Five scales were found: Child-Related Barriers, Parent-Related Barriers-Vegetables and Fruit, Parent-Related Barriers-Added Sugars, Social Context-Related Barriers, and Cost-Related Barriers. All scales presented adequate reliability. We found weak to moderate, negative, and significant correlations between child- and parent-related barriers regarding vegetables and fruits, feeding practices to promote children's eating self-regulation, and food parenting self-efficacy. Additionally, parents who perceived their children as easy and well-regulated reported significantly fewer child-related barriers than parents with poorly self-regulated and inhibited children. The results support the instrument's preliminary psychometric adequacy regarding its validity and reliability and corroborate earlier empirical studies about the main parental barriers when promoting young children's healthy eating habits.
社会认知模型表明,感知到的障碍在促进健康行为方面起着至关重要的作用,包括健康饮食。我们旨在开发一种新的问卷来评估父母对幼儿健康喂养的感知障碍,并对该工具进行初步的心理测量评估。初始项目池是基于文献回顾和定性研究开发的。首先,我们进行了一项在线描述性横断面研究,共纳入了 278 名 2-6 岁儿童的家长,以检验其因子结构和内部一致性。然后,第二项研究在类似的人群中纳入了 168 名家长,评估了其聚合/区分效度和已知群体的有效性。探索性因子分析证实了该量表的理论结构。发现了五个量表:儿童相关障碍、父母相关障碍-蔬菜和水果、父母相关障碍-添加糖、社会环境相关障碍和成本相关障碍。所有量表的信度都较好。我们发现,在蔬菜和水果方面,父母对孩子和自身的障碍呈负相关,与促进孩子饮食自我调节的喂养实践以及养育孩子的自我效能感呈负相关。此外,与自我调节能力差、抑制性强的孩子的父母相比,认为自己孩子容易且自我调节能力强的父母报告的儿童相关障碍明显较少。结果支持该工具在有效性和可靠性方面的初步心理测量学充足性,并证实了早期关于促进幼儿健康饮食习惯时父母主要障碍的实证研究。
