Effective family functioning, such as communication, family organization, and family cohesion, is essential for family well-being and child development. Promoting family physical activity (PA) through shared activities offers a promising strategy for enhancing family dynamics. Developing a strong parenting PA identity (e.g., seeing oneself as a parent who supports their child's PA) and a family social identity around PA (e.g., perceiving the family as an active unit) may further strengthen motivation and commitment to engaging in PA. This study aims to evaluate the efficacy of three family PA interventions: (1) PA education alone; (2) PA education + PA parenting self-regulation skills; and (3) PA education + PA parenting self-regulation skills + PA parenting identity. The primary outcome is family cohesion, a key dimension of family functioning. Secondary objectives include examining the effects of these interventions on (1) family-functioning dimensions of flexibility and organization, (2) child PA levels and parent-child co-participation in PA, (3) parental PA support and its potential antecedents (i.e., parental support constructs derived from the Multi-Process Action Control Framework, and parent-perceived family PA social identity), and (4) exploring potential moderating effects of seasonal variation, child and parent characteristics, intervention adherence, and PA type.
The three-armed, single-blind randomized controlled trial compares the efficacy of the three interventions over a 6-month period. Families are eligible if they have a child between the ages of 6 and 12 who is not meeting the Canadian 24-Hour Movement Guidelines for Children and Youth. Participants are randomly assigned to one of the three intervention groups. Family functioning, child PA and parent-child co-participation in PA, parental PA support, family PA social identity, and related constructs (e.g., perceived capability and opportunity, behavioral regulation, and habit) are assessed at baseline, 6 weeks, 3 months, and 6 months post-intervention. Recruitment methods include social media, recruitment poster drops, and community-based promotion.

有效的家庭功能，如沟通、家庭组织和家庭凝聚力，对于家庭幸福和儿童发展至关重要。通过共同活动促进家庭体育活动（PA）为增强家庭动态提供了一个有前景的策略。培养强烈的育儿体育活动身份认同（例如，将自己视为支持孩子体育活动的父母）以及围绕体育活动的家庭社会身份认同（例如，将家庭视为一个活跃的单位）可能会进一步增强参与体育活动的动机和承诺。本研究旨在评估三种家庭体育活动干预措施的效果：（1）单独的体育活动教育；（2）体育活动教育 + 体育活动育儿自我调节技能；以及（3）体育活动教育 + 体育活动育儿自我调节技能 + 体育活动育儿身份认同。主要结果是家庭凝聚力，这是家庭功能的一个关键维度。次要目标包括研究这些干预措施对以下方面的影响：（1）家庭功能的灵活性和组织维度；（2）儿童体育活动水平以及亲子共同参与体育活动的情况；（3）父母对体育活动的支持及其潜在前因（即源自多过程行动控制框架的父母支持结构，以及父母感知的家庭体育活动社会身份认同）；以及（4）探索季节变化、儿童和父母特征、干预依从性以及体育活动类型的潜在调节作用。
这项三臂单盲随机对照试验在6个月的时间内比较这三种干预措施的效果。如果家庭中有一名6至12岁的儿童未达到加拿大儿童和青少年24小时运动指南的要求，则该家庭符合条件。参与者被随机分配到三个干预组之一。在干预前的基线、干预后6周、3个月和6个月时，评估家庭功能、儿童体育活动以及亲子共同参与体育活动的情况、父母对体育活动的支持、家庭体育活动社会身份认同以及相关结构（例如，感知能力和机会、行为调节和习惯）。招募方法包括社交媒体、发放招募海报以及基于社区的推广。
