Developmental neuroscience models suggest that changes in responsiveness to incentives contribute to increases in adolescent risk behavior, including substance use. Trajectories of sensitivity to reward (SR) and sensitivity to punishment (SP) were examined and tested as predictors of escalation of early substance use in a community sample of…

Depression often emerges early in the lifecourse and is consistently shown to be associated with poor self-esteem. The 3 main objectives of the current study are to (1) evaluate the association between a history major depression and self-esteem in young adulthood, (2) assess the relationship between timing of depression onset and young adult…

Bullying and victimization occurring in adolescence can have a long-lasting negative impact into adulthood. This study investigates whether conduct problems (CP) and dimensions of psychopathy predict the developmental course of bullying and victimization from ages 12 to 14 among 1,416 Greek-Cypriot adolescents. Results indicate that initial levels…

Concern exists that youth who spend a lot of time participating in organized out-of-school activities (e.g., sports) are at-risk for poor developmental outcomes. This concern--called the over-scheduling hypothesis--has primarily been assessed in terms of adolescent adjustment. This longitudinal study of a nationally representative sample of 1,115…

The association between marijuana use and depressive symptoms was examined longitudinally in a sample of 622 African American youth, interviewed on six occasions, using hierarchical linear modeling (HLM). We considered whether depressive symptoms predicted changes in marijuana use and vice versa from high school through the transition into young…

This study investigated ego developmental differences in adolescent academic orientations and academic achievement. A sample of 142 male and female high school students completed the Washington University Sentence Completion Test and self-report measures assessing academic locus of control, learning orientation (LO), and grade orientation (GO).…

Used a bio-psychosocial approach to examine predictors of onset of sexual intercourse among adolescents interviewed at ages 13-14, 16-17, and 22-23 years. Found that for girls, always-married parents and less dating alone predicted later first intercourse. Earlier timing of first intercourse for boys was related to associating with peers with…

Used prospective life history data from the National Child Development Study of Great Britain to examine family life risk factors and how their effects on teen childbearing risk varied, depending on the childhood age at which they were experienced. Demonstrated that socioeconomic status, family stress, and parental involvement in education during…

Examined impact of peer experience on seventh graders' strategies for coping with peer hassles. Found that more aggressive adolescents perceived more control over hassles. More aggressive, unpopular adolescents used more negative strategies; more popular aggressive females used more problem-focused strategies. Withdrawn adolescents perceived less…

The current study presents a growth curve analysis of self-esteem among Black, Latino, and Asian American high school students. A series of hierarchical linear models were used to examine patterns and predictors of change in self-esteem over time. Results revealed an average increase in self-esteem with age. Although boys and girls experienced…

Examined relations between U.S., Korean, and Chinese adolescents' misconduct and their perceptions of others' behavior and attitudes toward youth misconduct. Found that U.S. youths engaged in more misconduct than other groups. Perceived behavior and sanctions of close friends were strongest predictors of misconduct in all cultures. Found unique…

Examined associations between parental monitoring and adolescent adjustment. Found that higher monitoring was associated with higher grade point average, lower depression, less sexual activity and minor delinquency, except for boys' depression. Monitoring effects increased across grade level for boys and decreased for girls. Monitoring predicted…

Investigated relation between pubertal timing and alcohol use among junior high school students in Norway who were followed up 2 years later. Found that early timing of puberty correlated with number of intoxication incidents and number of units consumed on each occasion and, to a lesser degree, with frequency of alcohol use. Correlations were…

Evaluated the longitudinal implications of age-18 dysphoric mood in 23-year olds using a multidata, multi informant design. Findings indicated that adolescent dysphoric mood was an important predictor of psychological distress in young adults, especially in young adult women, for whom the prospective correlations of adolescent dysphoria were more…

Investigated relationships among prenatal maternal resources, perceptions about parenting, and children's temperament at 6 months, and adaptation of 90 adolescent mothers three years after the birth of their first child.
