Despite the unequivocal benefits of regular physical activity, many parents engage in lower levels of physical activity (PA) following the birth of a child. Drawing on the theory of planned behaviour (TPB) and health action process approach (HAPA), an integrative model was developed to examine variables predicting PA in parents of very young children. In addition, key beliefs related to PA intentions and behaviour among parents of very young children were investigated.
A prospective-correlational design with two waves of data collection, spaced one week apart, was adopted.
Parents (N = 297) completed an online- or paper-based questionnaire assessing TPB global constructs and belief-based items as well as family social support and planning from the HAPA. One week later, parents self-reported their PA behaviour. Data were analysed using latent variable structural equation modelling.
Findings revealed the model was a good fit to the data, accounting for 62% and 27% of the variance in PA intentions and behaviour, respectively. Attitude, subjective norm, and perceived behavioural control predicted intentions. Family social support failed to predict both planning and intentions. Physical activity was predicted by planning only, with an indirect effect occurring from intentions to behaviour through planning. A number of key beliefs on intentions and behaviour were also identified.
This formative research provides further understanding of the factors that influence the PA behaviour of parents of very young children. Results provide targets for future interventions to increase PA for parents in a transition phase where PA levels decline. Statement of Contribution What is already known on this subject? Despite physical activity benefits, many parents are inactive following the birth of a child Social-cognitive models have demonstrated efficacy in predicting physical activity Weaknesses are inherent in the use of single theories to explain behaviour What does this study add? Use of integrative models allows for meaningful prediction of parental physical activity A range of key beliefs were found to be related to parental physical activity Results can inform future physical activity interventions for parents of very young children.
尽管有规律的身体活动有明确的益处，但许多父母在孩子出生后身体活动水平较低。本研究以计划行为理论（TPB）和健康行动过程方法（HAPA）为基础，构建了一个综合模型，以检验预测幼儿父母身体活动的变量。此外，还研究了与幼儿父母身体活动意向和行为相关的关键信念。
采用前瞻性相关设计，分两阶段进行数据收集，两阶段间隔一周。
父母（N=297）通过在线或纸质问卷评估 TPB 整体结构以及 HAPA 中的信念相关项目和家庭社会支持、计划。一周后，父母自我报告身体活动行为。采用潜变量结构方程模型对数据进行分析。
研究结果显示，该模型数据拟合度良好，分别解释了身体活动意向和行为变异的 62%和 27%。态度、主观规范和感知行为控制预测了意向。家庭社会支持未能预测计划和意向。身体活动仅由计划预测，意向通过计划对行为产生间接影响。还确定了与意向和行为相关的一些关键信念。
这项探索性研究进一步了解了影响幼儿父母身体活动行为的因素。研究结果为未来干预措施提供了目标，以提高处于身体活动水平下降过渡期的父母的身体活动水平。
