Does Measurement Discrepancy Vary by Level of Risk Behavior?
B Iritani, D Hallfors Pacific Institute for Research and Evaluation, Chapel Hill, NC Background: Previous research suggests discrepancies between self-reported STD prevalence and assay point prevalence, but no such studies have yet been conducted with a nationally representative sample of young adults. Objectives: To assess self-report versus assay STD/HIV prevalence among a representative sample of young adults by their type and degree of risk behavior. Methods: Data are from Wave 3 of the National Longitudinal Study of Adolescent Health, a nationally representative sample of 18-26 year olds (N=15,197). Data contain results of Chlamydia, Gonorrhea, and Trichomoniasis urine tests and HIV saliva test in addition to self-reports of these infections. Bivariate association between self-reported and assay STD results are examined for respondents clustered into 16 different groups based on their sexual and drug use behaviors. Then, clusters are used to predict STD outcomes in logistic regres
