Grounded in the expectancy-value theory, this study examined how parental expectancy-value beliefs influence children's physical activity, as well as the mediating roles of parental exercise inputs and children's exercise self-efficacy, with children serving as the research subjects.
Data were collected from 1,284 children and their parents in South China using the , and . Path analysis was conducted employing structural equation modeling techniques.
(1) Parental expectancy-value beliefs, parental exercise input, children's exercise self-efficacy, and children's physical activity exhibited significant positive correlations (P ≤ 0.05). (2) Parental expectancy-value beliefs had a positive direct effect on children's physical activity (β = 8.898, 95% CI [4.754, 13.041]). (3) Parental exercise input positively influenced children's exercise self-efficacy (β = 1.178, 95% CI [0.147, 2.323]), which subsequently positively affected children's physical activity (β = 3.028, 95% CI [1.630, 4.603]). Furthermore, the chain mediation of parental exercise input and children's exercise self-efficacy indirectly influenced children's physical activity (β = 0.974, 95% CI [0.564, 1.498]).
Parental expectancy-value beliefs significantly enhanced both parental exercise input and children's exercise self-efficacy, which subsequently promoted children's physical activity behavior. Future interventions aimed at improving children's PA levels should prioritize strengthening parental expectation beliefs, enhancing parental input to exercise, and boosting children's exercise self-efficacy.
基于期望价值理论，本研究以儿童为研究对象，探讨父母的期望价值信念如何影响儿童的身体活动，以及父母的运动投入和儿童的运动自我效能感的中介作用。
使用[具体量表名称未给出]，从中国南方的1284名儿童及其父母那里收集数据。采用结构方程建模技术进行路径分析。
（1）父母的期望价值信念、父母的运动投入、儿童的运动自我效能感和儿童的身体活动之间存在显著正相关（P≤0.05）。（2）父母的期望价值信念对儿童的身体活动有直接正向影响（β = 8.898，95%CI[4.754, 13.041]）。（3）父母的运动投入对儿童的运动自我效能感有正向影响（β = 1.178，95%CI[0.147, 2.323]），随后对儿童的身体活动有正向影响（β = 3.028，95%CI[1.630, 4.603]）。此外，父母的运动投入和儿童的运动自我效能感的链式中介间接影响儿童的身体活动（β = 0.974，95%CI[0.564, 1.498]）。
父母的期望价值信念显著增强了父母的运动投入和儿童的运动自我效能感，进而促进了儿童的身体活动行为。未来旨在提高儿童身体活动水平的干预措施应优先加强父母的期望信念，增加父母对运动的投入，并提高儿童的运动自我效能感。
