This study examines the relationship between sibling delinquency and respondent risky behavior of emerging adults. This study attempts to understand the influence a sibling has on deviant behavior, sexual permissiveness, and substance use. Sibling support and sibling contact were the two components of a sibling relationships that were examined. A social learning theory framework was used to organize the hypotheses and to discuss findings. It was hypothesized that an individual who has high contact and support from a deviant sibling would be more likely to engage in deviant behavior, be more sexually permissive, and have increased alcohol use. The sample was comprised of over 700 undergraduates enrolled in a large state university. A test of the mediating and moderating effects of sibling support and contact was conducted. Results indicate that there is a mediating effect and a moderating relationship between the influence of sibling delinquency and respondent deviance, sexual permissiveness, and alcohol use for females. This means that as contact and support with a delinquent sibling increases, the level of respondent deviance, sexual permissiveness, and alcohol use also increases.
