Parental supportive behavior (PSB) plays a pivotal role in shaping children's 24-hour movement behaviors (24-HMB), including light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), sedentary screen time (SST), and sleep. However, the psychosocial determinants and the changing process of PSB remain understudied. Using a three-wave prospective design over four months, this study examined the psychosocial mechanisms of PSB towards children's 24-HMB based on an adapted health action process approach (HAPA) framework among 812 parents (36.61 ± 3.80 years; 68.7% female). The adapted HAPA model demonstrated acceptable fit indices (CFI = .952-.980, TLI = .946-.967), incorporating the original HAPA model along with past behavior and affective attitude. The model explained 31.6%-54.8% of the variance in PSB across the four outcomes (LPA, MVPA, SST, and sleep). Motivational self-efficacy and outcome expectancy consistently predicted intentions, while intentions and action control emerged as stable predictors of PSB across all four outcomes. The prediction of planning, and volitional self-efficacy on PSB varied by movement behaviors. Both past behavior and positive affective attitude were directly associated with PSB, while their inclusion attenuated most pathways in the original HAPA model. Further, intention and action control served as prominent mediators between past behavior, affective attitude, and PSB across all outcomes. Future research could leverage the adapted HAPA framework to guide the development of parent-based interventions aimed at improving children's 24-HMB.
父母支持行为（PSB）在塑造儿童24小时运动行为（24-HMB）方面起着关键作用，包括轻度身体活动（LPA）、中度至剧烈身体活动（MVPA）、久坐屏幕时间（SST）和睡眠。然而，PSB的社会心理决定因素及其变化过程仍未得到充分研究。本研究采用为期四个月的三波前瞻性设计，在812名父母（年龄36.61±3.80岁；68.7%为女性）中，基于适应性健康行动过程方法（HAPA）框架，研究了PSB对儿童24-HMB的社会心理机制。适应性HAPA模型显示出可接受的拟合指数（CFI = 0.952 - 0.980，TLI = 0.946 - 0.967），纳入了原始HAPA模型以及过去的行为和情感态度。该模型解释了四个结果（LPA、MVPA、SST和睡眠）中PSB变异的31.6% - 54.8%。动机自我效能感和结果期望始终能预测意图，而意图和行动控制在所有四个结果中均是PSB的稳定预测因素。计划和意志自我效能感对PSB的预测因运动行为而异。过去的行为和积极的情感态度均与PSB直接相关，而将它们纳入模型后减弱了原始HAPA模型中的大多数路径。此外，意图和行动控制在所有结果中均是过去行为、情感态度和PSB之间的重要中介因素。未来的研究可以利用适应性HAPA框架来指导旨在改善儿童24-HMB的基于父母的干预措施的开发。
