Adolescents face a high risk for HIV infection given their sexual behavior, variety of sexual activities in which they engage (intercourse, anal sex, and oral sex), their lack of contraceptive protection, and their drug use behavior. (1,2) They also face increased risk because of their impulsiveness, desire for immediate gratification, and their tendency to perceive themselves as invincible. Because of the long incubation period for development of AIDS (8-12 years), and because better than one in five AIDS cases are diagnosed between ages 20-29, at least one-fifth of AIDS cases probably develop during adolescence. (3)
The earliest study of adolescents' AIDS knowledge was conducted in 1983. (4) A multitude of surveys since then have found significant deficiencies in adolescents' AIDS-related knowledge and beliefs. (5-10) Some studies (11,12) that focused specifically on AIDS knowledge and beliefs of minority adolescents indicated further education about AIDS prevention is necessary to help maximize adolescents' understanding of AIDS.
While several studies have assessed adolescents' knowledge and beliefs of AIDS, fewer studies have assessed the effects of AIDS education programs in schools. Only eight studies that evaluated the effectiveness of AIDS education programs in secondary schools were identified (Table 1). These eight studies all contained evaluation instrument deficiencies. Five did not identify reliability assessments for their instruments, six did not report validity assessments, and none used instruments based on a theoretical behavioral model. (13-20) The evaluation instrument deficiencies bring into question the effectiveness of secondary school AIDS education programs.
