This research examines whether prior research may not have detected cultural-specificity in the role of controlling and autonomy-supportive parenting in children's adjustment because of reliance on between-individual analyses. In two longitudinal studies (Ns = 825 and 934) of early adolescents, within-individual analyses were conducted to examine…
