The value of physical change in adolescence: Consequences for the parent-adolescent exchange relationship.

This research examines the effects of specific physical changes associated with puberty on peer and parent relationships of early and middle adolescent white boys. The data used are from a longitudinal study of Milwaukee school children conducted by Simmons and Blyth (1979). On the basis of past research, most of the physical changes that occur during puberty were expected to increase peer status. According to Richer's (1968) exchange model, these positive effects in the domain of peer relations should, in turn, reduce the resource dependency of the adolescent on his parents. As a result, greater independence from parents should ensue and the likelihood of conflict should increase. As expected, significant positive relationships were found for the effects of various physical changes on most peer status variables and independence from parents. However, no significant relationships were found for the effects of physical changes on parent-adolescent relationship quality or conflict with parents. Also contrary to expectations, controlling for changes in peer status did not alter the positive effects of physical change on independence from parents. Finally, tests for interactions showed that the parent-adolescent relationship was negatively affected when parents did not grant greater independence to the physically changing adolescent. In conclusion, it is suggested that while resource dependencies may indeed change during puberty, parents alter their expectations for their children and grant greater independence based on the adolescent's physical appearance alone.
