Bold text highlights significant effects for focal parental movie restriction predictors of substance use initiation. Step 1 of adjusted analyses controls for socio-demographic variables, Step 2 for general time-invariant covariates, Step 3 for parenting covariates, Step 4 for exposure to alcohol use content in movies, and Step 5 controls for personal characteristics
