Ss. Luthar et G. Cushing, SUBSTANCE USE AND PERSONAL ADJUSTMENT AMONG DISADVANTAGED TEENAGERS -A 6-MONTH PROSPECTIVE-STUDY, Journal of youth and adolescence, 26(3), 1997, pp. 353-372
Using a 2-wave longitudinal design with a 6-month interval, associatio
ns were examined between substance use and emotional/behavioral adjust
ment among 138 inner-city ninth-grade students. Substance use was oper
ationalized in terms of self-reported severity of problems associated
with use of alcohol, marijuana, and other drugs. Adjustment was measur
ed based on various sources including ratings by the self by peers, an
d by teachers, as well as school records. Cross-sectional data indicat
ed that drug use showed associations in expected directions with all i
ndices of adjustment with the exception of peer-rated sociability. Lon
gitudinal analyses indicated that high level of drug use early in the
year were related to subsequent increases in behavioral and emotional
maladjustment. Early maladjustment, across different domains, converse
ly, was minimally associated with escalations in drug use. Results are
discussed in terms of mechanisms potentially underlying prospective a
ssociations, as well as implications for interventions.
