Can female adolescents tell whether they will test positive for Chlamydia infection?

Having better predictors of chlamydia infection may improve health care providers' decisions about when to provide testing for Chlamydia trachomatis (Ct). Adolescents' probability judgments of significant life events in the next year and by age 20 y have shown promising validity, being significantly correlated with subsequent self-reports of having experienced these events. Here, the authors examine whether female adolescents' probability judgments of having chlamydia were correlated with the objective outcome of a Ct polymerase chain reaction assay.
