This study examined pubertal maturation, pubertal timing and outcomes, and the relationship of puberty and sexual identity developmental milestones among 507 lesbian, gay, and bisexual youth. The onset of menarche and spermarche occurred at the mean ages of 12.05 and 12.46, respectively. There was no statistically significant difference in…

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…

Participation in the federally-subsidized school breakfast program often falls well below its lunchtime counterpart. To increase take-up, many districts have implemented Breakfast in the Classroom (BIC), offering breakfast directly to students at the start of the school day. Beyond increasing participation, advocates claim BIC improves academic…

Data from the Nurse-Family Partnership intervention program were analyzed to compare the "selection" versus "unique" effects of maternal jail time on adolescent antisocial and health risk outcomes. Data from 320 women and their firstborn children were available from the prenatal, birth, and 15-year assessments. Consistent with…

Identification of the causes of child maltreatment perpetration is prerequisite for developing efficacious prevention initiatives to reduce its occurrence. Earlier maltreatment victimization is often suggested as an important cause of subsequent maltreatment perpetration. This study investigates a) whether maltreatment victimization causes…

This article examines the relationship between after-school program quality, program attendance, and academic outcomes for a sample of low-income after-school program participants. Regression and hierarchical linear modeling analyses use a unique longitudinal data set including 29 after-school programs that served 5,108 students in Grades 4 to 8…

Objective: To examine the relation between parental familism (strong values of attachment to nuclear and extended family members) and youth antisocial behaviors over time. Method: Puerto Rican children 5 to 13 years of age at baseline residing in the South Bronx in New York (n = 1,138) and in the Standard Metropolitan Area in San Juan and Caguas,…

This study used a representative metropolitan sample to make longitudinal comparisons of college-bound and non-college-bound youth on incidents and predictors of heavy drinking. Respondents in the six-wave study were ages 13-16 at wave 1 and 18-21 at wave 6 (n's ranged from roughly 425-500 for different analyses). College/non-college comparisons…

Studies mental health services use by children of varying ages, sexes, socioeconomic status, and urbanicity of residence in a sample of 760 children. Prevalence of mental disorder is compared for various subgroups, and the extent to which use of services is consonant with prevalence differences is explored. (SLD)

This study applied individual growth trajectory analyses and person-oriented analysis to identify common profiles of out-of-school activity engagement trajectories among racially and ethnically diverse inner city teens (N = 1,430). On average, teens exhibited declining trajectories of participation in school-based and team sports activities and…

As part of a longitudinal study of the New York State Experimental Prekindergarten Program (PreK), several measures were administered to the four-year-old children in the fall of 1975 and to a sample of the same children in the spring of 1976. Analyses of covariance were carried out on three measures of cognitive development with one of five…

Approximately 6,500 children are enrolled per year in the New York State Experimental Prekindergarten Program (PreK). In 1975-76 a longitudinal study was begun to determine the program's impact on the development of children while enrolled in the program and in the primary grades. Samples from a population of 5,245 four-year-old prekindergarten…
