Social support as a factor in African-American adolescents' sexual risk behavior

African-American adolescents (N = 295) reporting high or low levels of social support completed measures of AIDS knowledge, health locus of control, attitudes toward condoms, self-reported sexual behavior for the preceding 12 months, perceptions of personal HIVrisk, and self-and response-efficacy ratings. Adolescents with less social support were less knowledgeable about AIDS, held more negative attitudes toward condoms, and were lower in selfefficacy than adolescents with higher levels of social support. Adolescents with fewer social supports also were significantly more likely to engage in casual sex, reported more nonmonogomouspartners, morefrequent coercions into unwanted sexual activity, and higher rates of sexually transmitted diseases. African-American males with low social support scores engaged in more frequent unprotected sexual activity with a larger number of sex partners and used condoms less often. The implications of these results for prevention efforts targeting minority adolescents are discussed.
