The development of decision-making autonomy was examined in 76 middle-class African American early adolescents (M=13 years) and their mothers, who were followed longitudinally for 5 years. Adolescent decision-making autonomy over conventional, prudential, multifaceted, and personal issues increased over time but at different rates. Mothers viewed prudential and conventional issues as parent decisions, but adolescents increasingly viewed them as joint. Adolescents viewed multifaceted and personal issues as increasingly decided by adolescents (with parental input), whereas mothers viewed them as joint. Greater autonomy over multifaceted issues in early adolescence was associated with poorer adjustment. Controlling for background variables and earlier adjustment, increased autonomy over personal and multifaceted issues predicted less depression and better self-worth in late adolescence.
