Peer isolation and drug use among white non-Hispanic and Mexican American adolescents.

The social-emotional characteristics and drug-use patterns of adolescents who reported having no friends (i.e., isolates) were compared to those of adolescents in drug-using and non-drug-using peer groups. Adolescents who did not have drug-using peers reported the lowest drug use and those with drug-using peers had the highest drug use, with adolescents who were isolated falling in between. Isolated youth reported more shyness, greater feelings of alienation, and lower social acceptance than did those in the other groups. Isolated youth also reported more anger and depression than did youth with non-drug-using peers, but less anger and equivalent depression when compared to adolescents with drug-using peers. Results are discussed in terms of social-emotional characteristics of isolated youth and risk/protective factors.
