Time use differences in activity participation among children 4-5 years old with and without the risk of developing conduct problems

► We examine young children's activity participation comparing children at risk of developing conduct problem and those not at risk. ► We examine differences in time spent in physical, structured, restful, and socially engaged activities. Differences were identified in risk oriented physical activity participation and social participation associated with adult supervision. ► We conclude that activity participation, level of adult supervision received, and rest be considered when looking at supporting young children at risk of conduct problems.
