In considering the influences of microsystems on adolescent substance use,
familial and peer contexts have received the most extensive attention in th
e research literature. School and neighborhood settings, however, are other
developmental contexts that may exert specific influences on adolescent su
bstance use. In many instances, school settings are organized to provide ed
ucational services to students who share similar educational abilities and
behavioral repertoires. The resulting segregation of students into these se
ttings may result in different school norms for substance use. Similarly, n
eighborhood resources, including models for substance use and drug safes in
volvement, may play an. important role in adolescent substance use. We brie
fly review literature examining contextual influences on adolescent substan
ce use, and present results from two preliminary studies examining the cont
ribution of school and neighborhood context to adolescent substance use. In
the first investigation, we examine the impact of familial, peer, and scho
ol contexts on adolescent substance use. Respondents were 283 students (age
s 13 to 18) from regular and special education classrooms in six schools. A
lthough peer and parental contexts were important predictors of substance u
se, school norms for drug use accounted for variance in adolescent use beyo
nd that explained by peer and parental norms. Data from a second study of 1
14 adolescents (mean age = 15) examines neighborhood contributions to adole
scent substance use. In this sample, neighborhood indices did not contribut
e to our understanding of adolescent substance use. Implications for preven
tion are: presented.
