The development of physical literacy (PL) early in life may influence children's subsequent physical activity (PA) participation and consequent health benefits across the life course. Interventions designed for parents are lacking, but such efforts can potentially enhance the PL of parents and their children's PA participation. Additionally, there is insufficient evidence to support the feasibility of delivering a PL intervention using an online format. Therefore, the purpose of this study was to examine the feasibility and effectiveness of a parent-focused, theory-driven, online-delivered intervention designed to improve the parents' PL and children's PA behaviors.
A non-randomized trial was conducted to evaluate the effects of the program. 224 Hong Kong families (primary school-aged children and their parents) registered to the program were considered the experimental group and were exposed to an online intervention over three months. Another 220 families in Hong Kong were considered the comparison group and did not receive any intervention. Outcome measures included PA behaviors (daily steps and moderate-to-vigorous PA), parent-child co-activity behaviors, family PA routines, and parent perceived PL. Linear mixed models were used to analyze the differences in terms of changes in measured outcomes between groups over time.
No significant group-by-time effects were found for children's or parents' PA behaviors. In terms of the family Co-PA routines, a small positive effect size in favor of the experimental group was found (p = .44, d = 0.2). Group-by-time effects favorable to the experimental group was detected for parent-child co-activity (p < .001, d = 0.7) and parental PL (p < .001, d = 0.9) at post-intervention. The results demonstrated that the intervention was acceptable and that there was potential for scale up.
Findings indicated that the intervention was effective in increasing parent-child co-activity and parent perceived PL. During the pandemic, online intervention delivery was found to be feasible. Using this mode of delivery, the intervention has the potential to reach a wide population in the local context.

生命早期身体素养（PL）的发展可能会影响儿童随后的体育活动（PA）参与度和终生健康获益。针对家长的干预措施较为缺乏，但此类干预措施有可能增强家长的 PL 以及其子女的 PA 参与度。此外，目前尚缺乏证据支持使用在线模式来实施 PL 干预的可行性。因此，本研究旨在检验以家长为中心、基于理论、在线实施的干预措施的可行性和有效性，该干预措施旨在提高家长的 PL 以及儿童的 PA 行为。
采用非随机试验来评估该方案的效果。224 个香港家庭（小学生及其家长）注册参与该项目，被视为实验组，并在三个月内接受在线干预。香港的另外 220 个家庭被视为对照组，不接受任何干预。结果测量包括 PA 行为（每日步数和中高强度 PA）、家长-儿童共同活动行为、家庭 PA 常规活动以及家长感知的 PL。采用线性混合模型分析组间随时间变化的测量结果差异。
未发现儿童或家长 PA 行为在组间存在显著的时间效应。在家庭共同 PA 常规活动方面，实验组有一个较小的、有利于实验组的积极效应量（p=0.44，d=0.2）。干预后，实验组在家长-儿童共同活动（p<0.001，d=0.7）和家长感知的 PL（p<0.001，d=0.9）方面的组间时间效应有利于实验组。结果表明，该干预措施是可以接受的，并且具有推广的潜力。
研究结果表明，该干预措施在增加家长-儿童共同活动和家长感知的 PL 方面是有效的。在疫情期间，在线干预的实施是可行的。通过这种模式的交付，干预措施有可能在当地环境中覆盖到更广泛的人群。
