In contrast to early theories of socialization which emphasized the role of parents in shaping their children's personalities, recent empirical evidence suggests an evocative relationship between adolescent personality traits and the quality of the parent-adolescent relationship. Research using behavior genetic methods suggest that the association between personality and parenting is genetically mediated, such that the genetic effects on adolescent personality traits overlap with the genetic effects on parenting behavior. In the current study, we examined whether the etiology of this relationship might change depending on the adolescent's personality. Biometrical moderation models were utilized to test for gene-environment interaction and correlation between personality traits and measures of conflict, regard, and involvement with parents in a sample of 2,452 adolescents (M age=17.79). We found significant moderation of both positive and negative qualities of the parentadolescent relationship, such that the genetic and environmental variance in relationship quality varied as functions of the adolescent's levels of personality. These findings support the importance of adolescent personality in the development of the quality of the parent-adolescent relationship.
Keywordspersonality; parenting; behavior genetics; moderation For many years, it was assumed that family environment, including parenting quality, played a causal role in personality development. This theory of socialization maintained that parents played the major, if not defining, role in child development (Bell, 1968). Subsequent to this, the dynamic interactionistic paradigm recognized that children were not simply the products of parental behavior (Caspi & Shiner, 2006;Magnusson, 1990; Patterson, 1982;Sameroff, 1983), but that individual differences in childhood personality also lead to variations in the quality of the parent-child relationship. Some took this position to its extreme, suggesting that parents have little if any impact on adolescent development (Harris, 1995(Harris, , 1998. A reasonable synthetic perspective is that child personality and parental behavior are related through "bidirectional interactive processes" (Collins, Maccoby, Steinberg, Heatherington, & Bornstein, 2000, p.222). In the current study, we examine whether the etiology of the parentadolescent relationship changes depending on the adolescent's personality by determining the

The Role of Adolescent Personality in the Parent-Adolescent RelationshipEvidence from the literature on personality development supports the notion of temperament (Rothbart & Bates, 2006), consisting of core traits (Asendorpf & Van Aken, 2003) or basic dispositions (McCrae & Costa, 1999) that are present from birth and have links to adult personality . This is not to say, however, that persona...
