This contribution focuses on the changes in parent-child relationships during the transition to adulthood, that implies a modification of the balance of connectedness and autonomy. The principal aim was twofold: 1) to verify how relational support and style of decision making - respectively markers of family connectedness and autonomy - change from adolescence to young adulthood; 2) to compare the perceptions of parents and children through a measure of agreement. The sample was composed of 259 Italian families with a child between 17 and 25 years of age. Participants filled out a self report questionnaire including the Parent-Adolescent Support Scale and the Style of Decision Making Scale. Results highlighted that children perceived a significant increase in relational support and in autonomy from late adolescence to young adulthood. Furthermore, agreement between parents and children increased by aging. Therefore, near the transition to adulthood, parents and young adults are closer to each other than during late adolescence.
