Abstract

This study aimed to develop an extended model of goal-directed behavior (MGB) to more thoroughly explain the intention of adults to control body weight. The extended model integrates the crucial constructs and a newly added construct, mental health, as a formative second-order factor in the weight control context into the original MGB. An online survey was conducted with 239 undergraduate students, who responded to the constructs of attitude, subjective norms, anticipated emotions, desire, and mental health. A descriptive analysis was conducted, and the fit of the proposed research model was verified using structural equation modeling. The results showed that the known constructs of attitude, subjective norm, and anticipated emotions were critical predictors of desire in the context of weight control. In addition, desire influenced intention to control weight. Furthermore, mental health had a significant causal relationship with the variables in the extended goal-directed behavior. It broadens the weight control literature by emphasizing the role of affective factors in weight control behavior, expanding the MGB theory with mental health, and providing empirical evidence for an effective weight control intervention program.

预测体重控制意图：目标导向行为的扩展模型。

本研究旨在建立一个目标导向行为（MGB）的扩展模型，以更彻底地解释成年人控制体重的意图。扩展模型将关键构念和一个新增加的构念——心理健康，作为体重控制背景下的形成性二阶因素整合到原始的MGB中。对239名大学生进行了一项在线调查，他们对态度、主观规范、预期情绪、欲望和心理健康的构念做出了回应。进行了描述性分析，并使用结构方程模型验证了所提出研究模型的拟合性。结果表明，态度、主观规范和预期情绪的已知构念是体重控制背景下欲望的关键预测因子。此外，欲望也会影响控制体重的意愿。此外，心理健康与扩展目标导向行为的变量有显著的因果关系。通过强调情感因素在体重控制行为中的作用，拓宽了体重控制文献，拓展了MGB理论与心理健康的关系，为有效的体重控制干预方案提供了经验证据。

期刊介绍： International Journal of Environmental Research and Public Health (IJERPH) (ISSN 1660-4601) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes, and short communications in the interdisciplinary area of environmental health sciences and public health. It links several scientific disciplines including biology, biochemistry, biotechnology, cellular and molecular biology, chemistry, computer science, ecology, engineering, epidemiology, genetics, immunology, microbiology, oncology, pathology, pharmacology, and toxicology, in an integrated fashion, to address critical issues related to environmental quality and public health. Therefore, IJERPH focuses on the publication of scientific and technical information on the impacts of natural phenomena and anthropogenic factors on the quality of our environment, the interrelationships between environmental health and the quality of life, as well as the socio-cultural, political, economic, and legal considerations related to environmental stewardship and public health. The 2018 IJERPH Outstanding Reviewer Award has been launched! This award acknowledge those who have generously dedicated their time to review manuscripts submitted to IJERPH.
