Conducted by the Henry J. Kaiser Family Foundation (see the February 9, 1999 Scout Report for Social Sciences), this new national survey of 15- to 17-year-olds examines their knowledge, awareness, attitudes, and behavior in relation to sexually transmitted diseases (STDs). Despite national estimates claiming that about one in four teenagers contracts an STD every year, most teens underestimate their personal risk and underrate the overall incidence of STDs. Moreover, many teens are mis- or uninformed about treatment and health consequences. The report provides survey highlights and methodology, a summary of findings, detailed results, and the survey questionnaire. A supplementary chart pack clearly presents key findings.
