Drug Misuse study with SNP Genotypes (Array) data on dbGaP (515 participants)

phs003442 — Early Family Prevention of Adolescent Alcohol, Drug Use, and    Psychopathology

The Early Steps Multisite Study is comprised of researchers from the University of Virginia, the University of Pittsburgh, Arizona State University, and Oregon Research Institute. This longitudinal study has been funded by the National Institute on Drug Abuse at the National Institutes of Health since 2002. The Early Steps Multisite Study conducted a randomized control trial to examine the effects of an intervention program called the Family Check-Up (FCU) offered in early to middle childhood. Outcomes include problem behaviors including substance use. Primary caregivers (PC) and their children (TC) were recruited from Women, Infant, and Children's (WIC) Nutritional Supplement centers in and around Pittsburgh, PA, Eugene, OR and Charlottesville, VA when target participating children were age 2. Participants were screened in three key areas of risk for later child conduct problems: (1) sociodemographic risk (e.g., poverty, teen parent status), (2) family risk (e.g. maternal stress, depressive symptoms), and (3) child conduct problems. Randomization to the intervention condition was balanced on gender to assure an equal number of males and females in the control and intervention groups. Data submitted to dbGaP are from the 515 subjects who were consented to provide a saliva sample.
