  1. Minimally adjusted models adjusted for age and gender. Standardized β for age and gender in minimally adjusted models ranged from 0.057 to 0.137 and -0.185 to -0.122, respectively. Fully adjusted models included all variables significant (p<0.10) in minimally adjusted models (as well as age and gender in the model of CAPL domains). Separate fully adjusted models were run for CAPL domains and individual CAPL components. Bolded variables were significant <0.10 in minimally adjusted models, and <0.05 in fully adjusted models. The fully adjusted models of CAPL domain scores and CAPL components accounted for 13% and 23%, respectively, of the total variance in total screen time in the full sample
