Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

Evidence from physiological studies has been integral in many causal theories of behavioral and emotional problems. However, this evidence is hampered by the heterogeneity characterizing these problems. The current study adds to prior work by identifying neuro-physiological markers associated with heterogeneity in conduct problems (CP),…

Although abundant research has demonstrated associations between psychologically controlling parenting and adolescent problem behavior, little is known about the moderating role of adolescent personality herein. This study examined whether adolescent personality moderates the associations between parental psychological control and internalizing…

This review used 4 types of longitudinal models (descriptive models, prediction models, developmental sequence models and longitudinal mediation models) to identify regular patterns of psychosocial development in adolescence. Eight patterns of adolescent development were observed across countries: (1) adolescent maturation in multiple…

This study examined the associations between sibling intimacy and conflict and youths' reports of risky behavior in a sample of adolescents ages 11-20. Participants were mothers, fathers, and sibling dyads in 393 families who were interviewed annually for 3, 4, or 5 years. Multivariate multilevel models tested longitudinal links between sibling…

Examined association between maternal responsiveness during infancy and middle-childhood behavior problems. Found that responsiveness was significantly associated with disruptive behavior problems but unrelated to attention problems. Absence of MRes during infancy increased risk of later disruptive behavior problems, even with concurrent parenting…

Examined predictive relations between infant assessments and behavior problems at age 7 in a low-income sample. Found that disorganized infant attachment behavior and below average mental development at 18 months were associated with externalizing behavior at 7 years. Avoidant infant attachment behavior was associated with later internalizing…

A biopsychosocial model of the development of adolescent chronic conduct problems is presented and supported through a review of empirical findings. The model posits that biological dispositions and sociocultural contexts place certain children at risk in early life but that life experiences with parents, peers, and social institutions increment…

Applied a semiparametric mixture model to a sample of 284 low-income boys to model developmental trajectories of overt conduct problems from ages 2 to 8. Identified four trajectories: persistent problem, high-level desister, moderate-level desister, and persistent low. Initially high and low groups were differentiated in early childhood by high…

Examined the relation between destructive sibling conflict and conduct problems among 5-year-old boys and their close-age siblings from low-income families. Found that the interaction between destructive sibling conflict and rejecting parenting predicted aggressive behavior problems across time and informants. Sibling conflict was related…

Used new longitudinal clustering technique to identify and compare groups of children with distinct longitudinal profiles of peer social preference during elementary school. Identified a stable popular group, stable average group, and unpopular group, all with decreasing social preference. Groups showed overlap over time with closest corresponding…

Examined relation of 7-year olds' attachment representations to later behavior and academic competency during middle childhood and adolescence. Controlled for social class, gender, IQ, perspective-taking ability, and prior competency. Found that attachment representations did not predict disruptive behavior or extroversion, but secure…

Studied relationship of temperament and same-sex peer interaction with gender differences in adjustment. Found that highly arousable boys who played with same-sex peers had increased problem behaviors. Arousable girls who played with other girls were relatively unlikely to show problem behaviors. The arousability and same-sex peer interaction…

Examined contributions of different risk factors to predicting children's psychological and academic outcomes at end of first grade. Found that each analysis level contributed to prediction of most outcomes; 18 to 29% of outcome variance was predicted; a common set of predictors predicted numerous outcomes; ethnicity showed little unique…

Examined relations among maternal depressive symptoms, family discord, and adolescent psychological adjustment. Found that maternal depressive symptoms were related to subsequent adolescent depressive symptoms, conduct problems, and academic difficulties for girls but not boys. Girls' greater vulnerability to family discord accounted for the…
