Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding data (the(More)
While marijuana use is common during adolescence, it can have adverse long-term consequences, with serious criminal involvement being one of them. In this study, we utilize longitudinal data from the Woodlawn Study of a community cohort of urban African Americans (N=702) to examine the effects of heavy adolescent marijuana use (20 or more times) on adult(More)
BACKGROUND Age of onset of substance use disorders in adolescence and early adulthood could be associated with higher rates of adult criminal incarceration in the U.S., but evidence of these associations is scarce. METHODS Propensity score matching was used to estimate the association between adolescent-onset substance use disorders and the rate of(More)
OBJECTIVE Using prospectively gathered data across a 35-year follow-up interval, we assessed the association of educational achievement and school behaviors with risk for the development of an alcohol-use disorder in adulthood. METHOD The baseline population consisted of 1242 first-grade students in 1966-1967 residing in the Woodlawn community of Chicago,(More)
BACKGROUND We examined developmental trajectories of marijuana use among a cohort of urban African Americans followed from first grade to mid adulthood. We compared risk factors in childhood and adolescence and consequences in mid adulthood across trajectory groups. METHODS Using semiparametric group-based mixture modeling, five marijuana trajectories for(More)
CONTEXT Despite prior evidence supporting cross-sectional associations of depression and alcohol use disorders, there is relatively little prospective data on the temporal association between depressed mood and maladaptive drinking, particularly across extended intervals. OBJECTIVE To assess the association between depressed mood in childhood and alcohol(More)
This study examines pathways to adult marijuana and cocaine use in a cohort of African Americans from Woodlawn, an inner city community in Chicago. Assessments were conducted in first grade (age 6), adolescence (age 16), early adulthood (age 32), and in mid-adulthood (age 42). The "social adaptation life course "framework guided the focus on social(More)
Studies have established a graded association between mental health and socioeconomic status (SES). However, scarce research has examined the impact of substance use disorders (SUD) and depression comorbidity on SES. We use data from the Woodlawn Study, a longitudinal cohort study, which recruited a cohort of first graders from Chicago starting 1966-1967(More)
The authors examined the effects of heavy adolescent marijuana use on employment, marriage, and family formation and tested both dropping out of high school and adult marijuana use as potential mediators of these associations among a community sample of African Americans followed longitudinally from age 6 to age 32-33. They used propensity score matching to(More)
