According to the findings, 45 percent of the sexually delinquent males had had sexual intercourse with a consenting female as compared to 89 percent of the non- delinquent runaway males. Fewer sexually delinquent males were knowledgeable about AIDS or were able to discriminate safe sexual behaviors from more risky behaviors. Both groups reported moderate support for beliefs about preventing HIV infection. These results indicate the need for more AIDS prevention education programs targeted at these high risk groups, although future research should focus on the relationship between general knowledge to beliefs, and how knowledge and beliefs are related to reducing unsafe sex and drug behaviors among youths at high risk. 5 tables and 42 references
