This dataset includes physical activity data, demographic information, and mental health assessments collected from children using Apple Watch Series 7. The dataset consists of multiple CSV files, each containing different aspects of the recorded data: id_T.csv: Contains one-hour aggregated activity id_F.csv: Includes activity fragments Demographic and mental health data (CSV format): Demographic variables: Age, sex, and BMI. Mental health assessments: Strengths and Difficulties Questionnaire (SDQ) Swanson, Nolan, and Pelham Version IV (SNAP-IV) Scale for ADHD assessment This dataset is structured to support research on the relationship between physical activity patterns and mental health outcomes in children. Some demographic data may be missing, and users are expected to handle the missing values as needed.
