目的：在这项研究中，我们测试了一个综合模型，为什么青少年消耗水果，蔬菜和水。该模型基于三种主要理论方法的研究证据，包括计划行为、社会规范和内在动机。方法：利用MyMovez项目（MyMovez, 2017）的4个数据采集波，采用结构方程建模对综合模型进行检验，共953名青少年参与，其中女生占53.9%,Mage = 11.19, SDage = 1.36。采用自我报告的方法评估青少年的水果、蔬菜和水的消耗、自我效能、态度、父母和同伴的社会规范、行为意图和内在动机。结果：分析显示，青少年吃水果和蔬菜或喝水的内在动机预测了他们的水果、蔬菜和水的消费量的变化。此外，青少年对父母的感知描述性规范（即对父母用水量普遍程度的感知）也预测了变化，但仅针对用水量。结论：目前的研究结果表明，青少年的内在动机（在某种程度上，父母的社会规范）是他们消费水果、蔬菜和水的最强预测因子。值得注意的是，行为意图并不能随着时间的推移预测他们的实际行为。因此，干预措施应侧重于增加青少年执行目标行为的内在动机，同时纳入社会环境的影响。
Objective: In this study, we tested an integrated model for why young adolescents consume fruit, vegetables, and water. The model was based on evidence from studies applying three dominant theoretical approaches, including planned behavior, social norms, and intrinsic motivation. Method: The integrated model was tested with structural equation modeling using four data-collection waves of the MyMovez Project (MyMovez, 2017) in which 953 young adolescents (53.9% girls; Mage = 11.19, SDage = 1.36) participated. Self-reported measures were used to assess young adolescents’ fruit, vegetable, and water consumption, self-efficacy, attitude, social norms of parents and peers, behavioral intentions, and intrinsic motivation. Results: The analyses revealed that young adolescents’ intrinsic motivation to eat fruits and vegetables or drink water predicted changes in their fruit, vegetable, and water consumption. Furthermore, adolescents’ perceived descriptive norm of parents (i.e., perception of the prevalence of their parents’ water consumption) also predicted changes, but only for water consumption. Conclusion: The current findings show that young adolescents’ intrinsic motivation (and, to some extent, parental social norms) is the strongest predictor of their consumption of fruit, vegetables, and water. It is important to note, behavioral intentions do not predict their actual behavior over time. Consequently, interventions should focus on increasing young adolescents’ intrinsic motivation to perform the targeted behavior while incorporating the influence of the social context.
