Abstract:
|
Surveys measure adolescent risk behavior (ARB) prevalence; some adolescents over-report their true risk behaviors, while others under-report. Over- and under-reports can be detected if adolescents report having engaged in a risk behavior and then recant the earlier report. Bayesian MCMC methods can estimate the prevalence of a disease without a gold standard test, and the specificity and sensitivity of existing tests. These methods are modified to include covariates to estimate the specificity and sensitivity of self-report for several ARBs and their prevalence. The implications for cross-sectional data are explored.
