OBJECTIVES This report examines (1) the prevalence of psychological and minor physical violence victimization in a nationally representative sample of adolescents and (2) associations between sociodemographic factors and victimization. METHODS Analyses are based on 7500 adolescents who reported exclusively heterosexual romantic relationships in the(More)
Release of the hormone cortisol represents a distress response to novel or stressful situations. Individual differences in such reactivity have been conceptualized as representing a relatively enduring, generalizable trait. In this study, cortisol responses to two experimentally manipulated "sexual" and "nonsexual" stressors were used to examine whether(More)
OBJECTIVE To explore the influence of preexisting social ties between romantic partners (ie, knowing the partner as a friend or acquaintance before a relationship was considered "romantic" by the adolescent) on sexual risk behaviors among adolescents. DESIGN, SETTING, AND PARTICIPANTS By using data from 6658 adolescents from Wave II of the National(More)
Scientific research has made major contributions to adolescent health by providing insights into factors that influence it and by defining ways to improve it. However, US adolescent sexual and reproductive health policies-particularly sexuality health education policies and programs-have not benefited from the full scope of scientific understanding.

Recent research has found that the dopamine D4 receptor (DRD4) gene and maternal insensitivity may interact to predict externalizing behavior in preschoolers. The current study attempted to replicate and extend this finding in a sample of 18-30-month-old children. The current study examined two distinct dimensions of parenting (warm-responsive and(More)

OBJECTIVE The purposes of this study were to demonstrate, using longitudinal data, that the pubertal rise in testosterone (T) is associated with subsequent increases in female sexual interest and activity, and to examine these relationships within the context of a social control variable. METHODS Using data from a 2-year panel study of approximately 200(More)
BACKGROUND Maltreatment by an adult or caregiver during childhood is a prevalent and important predictor of antisocial behaviors in adulthood. A functional promoter polymorphism in the monoamine oxidase A (MAOA) gene has been implicated as a moderating factor in the relationship between childhood maltreatment and antisocial behaviors.

An understanding of developmental phenomena demands a relational or coactive concept of causality, as opposed to a conceptualization that assumes that singular causes can act in isolation. In this article we present a developmental psychobiological systems view of relational (bidirectional, coactional) causality, in which it is proposed that developmental(More)
Strong cross-sectional relationships between testosterone (T) and sexual activity have been found for human adolescent males, even when level of pubertal development is controlled; however, it has not been demonstrated that sexual behavior increases over time as a consequence of hormonal changes. The purpose of this paper was to extend previous(More)
