The role of negative emotional reactivity and neighborhood factors in predicting marijuana use during early adolescence.

INTRODUCTION

Negative emotional reactivity and the neighborhood environment have been individually associated with marijuana use outcomes; however, less is known about whether neighborhood factors differentiate the association between negative emotional reactivity and marijuana use. The present study examined whether neighborhood risk (i.e., neighborhood problems) and protective factors (i.e., neighborhood social cohesion) moderated the relation between negative emotional reactivity and marijuana use during early adolescence.

METHODS

Participants were 775 adolescents (M = 10.95 ± 0.88 years; 69% male; 76% Caucasian), who reported on their past month frequency of marijuana use at Time 1 (when adolescents were 10-12 years old) and Time 2 (when adolescents were 12-14 years old). Mothers reported on neighborhood problems and neighborhood social cohesion at Time 1. Youth reported on their negative emotional reactivity at Time 2.

RESULTS

Negative binomial regression analyses indicated that neighborhood problems moderated the relationship between negative emotional reactivity and marijuana use. In particular, in the context of low neighborhood problems, individuals with lower negative emotional reactivity were at attenuated risk for marijuana use compared to individuals higher in negative emotional reactivity. In the context of high neighborhood problems, individuals were at heightened risk for marijuana consumption regardless of their negative emotional reactivity levels.

CONCLUSIONS

Findings suggest that individual-level factors alone do not sufficiently account for early marijuana use and that neighborhood problems play a role in risk for or abstention from using marijuana during early adolescence. Implications for prevention and intervention for marijuana use during adolescence are discussed.
