Interviews were conducted in a research laboratory on a university campus and transportation through a local taxi service was provided to families as needed. Before the interview, the caregiver was asked to give consent and the adolescent was asked to provide assent. Adolescents completed self-report measures reflecting their own behavior (e.g., intentions to use substances), their parent’s behavior (e.g., messages regarding substance use) and the behavior of their peers (e.g., approval of substance use). Caregivers also completed a variety of self-report measures reflecting their own behaviors (e.g., parenting practices) in addition to measures reflecting their perception of their child’s behavior (e.g., aggression, shyness). Data for the present study are taken from the first assessment and are based only on adolescent reports. Parents and children were interviewed in separate rooms to enhance privacy and all questionnaires were computer administrated. Items were read aloud to participants and entered directly into a computer by the interviewer. For questions deemed “sensitive” (intentions to use and peer approval/use of substances), adolescents input their responses directly into the computer. Demographic information of the 387 adolescents is presented in Table 1.
