In a longitudinal study of a cohort of boys, compared the characteristics of those who became adolescent fathers with those who did not, and of their children with other children. The adolescent fathers had more arrests and substance abuse problems than the other adolescents. Their children had more health problems than a group of normal control…

This study modeled physical and psychosocial aspects of home environment and personal characteristics in a cumulative risk heuristic. Found that elevated cumulative risk was associated with heightened cardiovascular and neuroendocrine parameters, increased deposition of body fat, and higher summary index of total allostatic load. Replicated…

Examined 4-year-olds for effects on IQ of prenatal cocaine exposure, exposure to other substances, risk factors, and neonatal medical problems. Found that maternal verbal IQ and low environmental risk predicted child IQ. Cocaine exposure negatively predicted children's overall IQ and verbal reasoning scores for boys only. Maternal harsh…

Scores on the Home Observation for Measurement of the Environment were higher for control families than for families with an alcoholic father. For preschool sons of alcoholic fathers, overall developmental quotient, motor development, and social development were less advanced than for control children. (BC)

Measures of visual and tactual recognition memory, tactual-visual transfer, and object permanence were obtained for preterm and full-term infants. Measures of tactual-visual transfer were correlated with later intelligence measures up to the age of five years. These correlations were independent of socioeconomic status, medical risk, and early…

Compared cognitive functioning of infants--at 8 and 18 months--with varying levels of prenatal cocaine exposure. Found that, with risk and polydrug exposure controlled, exposure groups did not differ at 8 months on Bayley Scales or recovery to a novel stimulus. Infants with heavy exposure or high environmental risk declined in mental development…

Examined the relations between family characteristics, childhood temperament, and convictions for violent and nonviolent offenses at age 18. Found that family factors were associated with both violent and nonviolent offenses, whereas childhood temperament was associated primarily with convictions for violent offenses. Results suggest potentially…

Used growth modeling to examine relationship of early parenting to cognitive, language, and social development from 6 to 40 months in full-term and very low birth weight (medically low or high risk) children. Found that behaviors that were sensitive to children's focus of interest and did not highly control or restrict their behaviors predicted…

Tested whether adolescent internalizing and externalizing problems, heavy alcohol use, fathers' parenting, and family conflict varied over time with fluctuations in fathers' alcohol impairment. Found that adolescent symptomology and family environment did not vary over time as function of different trajectories of paternal alcohol impairment.…

Examines methodological and conceptual issues related to the study of the effects of parental depression on children, focusing on the need to develop measures of relational behavior that are well-validated in high risk samples; relational assessments focused around central motivating systems; and methods that describe a variety of individual…

Examined the impact of 2 environmental factors--social class and family risk levels--and 2 biological factors--intraventricular hemorrhage (IVH) and medical risk--on the cognitive and motor development of 175 preterm infants. Family risk, early medical risk, and the interaction of family risk and IVH were found to be significant predictors of…

Examined longitudinally the relationship between biological and social risk factors and aggressive behavior patterns among high-risk Australian adolescents in three groups: early-onset persistent aggression, adolescent-onset aggression, and nonaggressive behavior groups. Findings revealed that the interaction of biological and social risk factors…

Used longitudinal study with adopted children to examine genotype-environment correlations for behavioral problems. Found that children genetically at risk for antisocial behavior were more likely to receive negative parenting from adoptive parents than children not genetically at risk. Most of the association between negative parenting and…

Tested model of gender's moderating effects on behavior problems among early adolescents. Found that increasing girls' internalizing symptoms were partly explained by greater stability in girls' interpersonal vulnerabilities and greater magnitude in coefficients linking girls' relationships with parents and peers and internalizing problems. Boys'…

This study investigated prospective risk factors for increases in body dissatisfaction in adolescent girls and boys in the Eating Among Teens Project. At the time of first assessment (Time 1), participants were a cohort of early adolescent girls (N = 440) and boys (N = 366) and a cohort of middle adolescent girls (N = 946) and boys (N = 764).…
