Motor skill competence (MSC) and perceived competence (PC) are primary correlates that are linked with physical activity (PA) participation, yet there is limited evidence of the mutual longitudinal or temporal associations between these variables in preschoolers. Therefore, this study's purpose was to examine the bidirectional relationships between MSC and PA, MSC and PC, and PC and PA in preschoolers over time.
The final sample were 61 preschoolers (M = 4.45 years, ranging from 4 to 5) from two underserved schools. MSC was assessed using the Test of Gross Motor Development, Second Edition (TGMD-2). PC was assessed using the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children. PA was assessed using ActiGraph GT9X Link accelerometers during three consecutive school days. All assessments of MSC, PC, and PA were measured in identical conditions at schools at the baseline (T1) and the end of the eighth week (T2). We employed a cross-lagged model approach to understand the bidirectional relationships between MSC, PC, and PA.
The results showed that T1 MSC significantly predicted T2 MSC ( < 0.01) and T1 MSC significantly predicted T2 PA only in girls ( = 0.03). Additionally, a cross-lagged effect of T1 MSC and T2 PC was only observed in boys ( = 0.03). Lastly, a significant association for T1 moderate-to-vigorous physical activity (MVPA) and T2 PC was only observed in girls ( = 0.04).
Bidirectional relationships between the variables were not observed in preschoolers. However, significant gender differences were observed in each cross-lagged model.
运动技能能力(MSC)和感知能力(PC)是与身体活动(PA)参与相关的主要因素,但关于这些变量在学龄前儿童中的相互纵向或时间关联的证据有限。因此,本研究的目的是探讨学龄前儿童随时间推移在MSC与PA、MSC与PC以及PC与PA之间的双向关系。
最终样本包括来自两所服务不足学校的61名学龄前儿童(平均年龄M = 4.45岁,年龄范围为4至5岁)。使用《粗大运动发展测试第二版》(TGMD - 2)评估MSC。使用《幼儿感知能力和社会接受度图片量表》评估PC。在连续三个上学日期间,使用ActiGraph GT9X Link加速度计评估PA。在基线期(T1)和第八周结束时(T2),在学校相同条件下对MSC、PC和PA进行所有评估。我们采用交叉滞后模型方法来理解MSC、PC和PA之间的双向关系。
结果表明,T1期的MSC显著预测T2期的MSC(<0.01),且T1期的MSC仅在女孩中显著预测T2期的PA(=0.03)。此外,仅在男孩中观察到T1期的MSC和T2期的PC之间存在交叉滞后效应(=0.03)。最后,仅在女孩中观察到T1期的中度至剧烈身体活动(MVPA)与T2期的PC之间存在显著关联(=0.04)。
在学龄前儿童中未观察到变量之间的双向关系。然而,在每个交叉滞后模型中均观察到显著的性别差异。
