Brody et al., 2006 | Youth 11 y/o and their parent (N = 332 dyads); 53.6% female youth; Ethnicity: AA Median income $1655 monthly Rural counties in GA | Design: Efficacy trial Assessment: Pre-txt/3-mos. post-txt Outcome: Health risk-taking behaviors Mechanism: Regulated-communicative parenting | Youth findings: Intervention youth demonstrated lower reports of risky behavior compared to control youth (P < .05) and youth-reported targeted parenting compared to control youth (P < .05).
