This longitudinal dataset tracks 631 early adolescents across four timepoints from baseline to a 6-month follow-up. Created by Rui Si Ma for a three-arm cluster randomized controlled trial, it measures the impact of family-supported interventions on physical activity and mental well-being. The data was last updated in March 2026 and is hosted on Harvard Dataverse.
Use Cases
- Evaluating the correlation between family support levels and physical activity behaviors
- Statistical modeling of mental well-being scores across four longitudinal timepoints
- Comparative analysis of intervention outcomes across the three trial arms
Strengths
- Three-arm cluster randomized controlled trial design
- Longitudinal tracking across 4 timepoints
- N=631 participant sample size
Limitations
- Sample size of 631 may limit generalizability to broader adolescent populations
- Focus is restricted to a specific 6-month post-intervention window
- Potential for self-reporting bias in behavioral and mental health metrics
