Examination of the Relationship Between Daily Perceptions of Collective Efficacy and Marijuana Use Among Black Youth: Does the Location of the Perception Matters?

Neighborhood-level collective efficacy protects Black youth from substance use; however, neighborhood research does not account for the entirety of adolescents' exposure or their perceptions of space which may be critical to understanding the role of context in substance use. To address this limitation, the SPIN Project recruited 65 Black adolescents (M(SD) = 15.32(1.06)) to complete four brief surveys each day for a month describing their perceptions of spaces and marijuana use. Multilevel negative binomial models were estimated to test the relationship between an individual's perceptions of collective efficacy and the marijuana used during a day, and if the location of the observations moderated these relationships. Findings indicated that the perceptions of collective efficacy protected adolescents from marijuana use when occurring within their home neighborhood, but not outside of it; thereby suggesting important variations in adolescents' perceptions based on the location that matter for Black youth marijuana use.
