This study examined the relationship between parents' and adolescents' confidence and competence in making decisions. Data were obtained from a survey sample of 584 adolescents, aged 12-18 years living in Adelaide, South Australia. Data were obtained from a sample of 352 parents of the adolescents by means of a mail survey. Parents' decision-making self-esteem was related to the self-esteem of young adolescents. The relationship was stronger for males than females. There was a relationship between mothers' decision-making competence and the competence of young female adolescents. Thus, partial support was provided for modelling theory in regard to the role of parents in the socialization of decision-making skills and confidence.
