Adolescence represents a critical developmental period, with changes in emotional regulation capacities influencing physical and mental health. With less than 6% of Canadian youth currently meeting the 24-hour movement guidelines for physical activity, sleep and sedentary behaviour, there is an urgent need to understand the potential association between movement behaviours, physical literacy, emotional regulation and mental health during adolescence. Additionally, there is a need to better understand these associations among equity-deserving groups. We developed the Adolescents' Daily Lives (ADL) project to identify how, when, under what contexts and to whom to promote healthy engagement in movement behaviours to optimise youth mental health.
For the ADL project, we will employ a 14-day intensive longitudinal design to investigate the associations between physical literacy, movement behaviours, emotion regulation and mental health among a diverse sample of 120 adolescents (ages 13-17 years) living in the Greater Victoria Area, British Columbia, Canada. A comprehensive baseline survey and movement competence test, assessing physical and mental well-being, 24-hour movement behaviours (ie, physical activity, sleep and sedentary behaviours) and physical literacy, will be accompanied by daily diary surveys and accelerometer-based movement tracking (ie, Fitbit Inspire 3) to assess daily fluctuations in movement behaviour, emotional regulation and mood. Multivariate analyses, including multilevel modelling, multilevel structural equation modelling and Bayesian hierarchical continuous-time SEM, will be used to model the repeated measures data and understand the simultaneous variations in daily movement behaviours, emotion regulation and mental health.
The ADL project received ethical approval from the University of Victoria Behavioural Research Ethics Board (protocol #22-0262). Study participation is voluntary, and data collection will be anonymised to protect participant privacy and confidentiality. Research findings will be shared through academic publications and conference proceedings. Through knowledge mobilisation resources, cocreated with the youth community advisory board, relevant findings will be shared directly with the wider community of adolescents.
青春期是一个关键的发展阶段，情绪调节能力的变化会影响身心健康。加拿大目前只有不到 6%的青少年符合身体活动、睡眠和久坐行为 24 小时运动指南，因此迫切需要了解青少年时期运动行为、身体素养、情绪调节和心理健康之间的潜在关联。此外，还需要更好地了解这些关联在权益相关群体中的情况。我们开展了青少年日常生活（ADL）项目，以确定如何、何时、在何种情况下以及向谁推广健康的运动行为，从而优化青少年的心理健康。
在 ADL 项目中，我们将采用 14 天的密集纵向设计，调查不列颠哥伦比亚省大维多利亚地区 120 名（年龄在 13-17 岁）不同青少年群体中身体素养、运动行为、情绪调节和心理健康之间的关联。全面的基线调查和运动能力测试将评估身体和心理健康、24 小时运动行为（即身体活动、睡眠和久坐行为）和身体素养，同时还将进行日常日记调查和基于加速度计的运动跟踪（即 Fitbit Inspire 3），以评估运动行为、情绪调节和情绪的日常波动。多变量分析，包括多层次建模、多层次结构方程建模和贝叶斯层次连续时间 SEM，将用于对重复测量数据进行建模，并了解日常运动行为、情绪调节和心理健康的同时变化。
ADL 项目获得了维多利亚大学行为研究伦理委员会的批准（协议号 22-0262）。研究参与是自愿的，数据收集将匿名化，以保护参与者的隐私和机密性。研究结果将通过学术出版物和会议论文集分享。通过与青年社区咨询委员会共同创建的知识转化资源，将直接向更广泛的青少年群体分享相关发现。
