Abstract
  • The current study examined the relationship between peer substance use and friendship intimacy in predicting adolescent self-medication. Two hypotheses were tested: 1) greater peer substance use is associated with less friendship intimacy, and 2) friendship intimacy and peer substance use moderate the temporal relationship between daily negative affect and subsequent substance use (i.e., self-medication). Experience sampling methods (ESM) were employed to capture daily variations in mood and substance use, and multilevel modeling techniques were used to parse between- versus within-person differences in risk for use. Findings did not support the primary hypotheses, indicating that characteristics of the peer context (i.e., intimacy and peer use) do not predict risk for self-medication among younger adolescents. However, there was a weak but consistent trend indicating that friendship intimacy and peer use interact to predict substance use more generally, such that the effect of friendship intimacy depends on the degree of peer use.
