Are adolescents accurate in self-report of frequencies of sexually transmitted diseases and pregnancies?
OBJECTIVE
Many surveys of adolescent behavior are dependent on self-reported data. We sought to assess the accuracy of adolescent self-report of sexually transmitted diseases (STDs) and pregnancies.


METHODS
We randomly selected 149 (118 females, 31 males) adolescents to participate in this accuracy study. Follow-up questionnaires were administered to the 126 patients (99 females, 27 males) who returned after enrollment. Patients were asked about STDs and pregnancies during the follow-up period which ranged from 6 months to 1 year. All patient charts were reviewed to validate post-testing history.


RESULTS
Return visits were made by 126 patients (84%). Fifty-one (40%) denied having had an STD at all during the follow-up period but were found to have had at least one STD. Another 11 (9%) admitted having had an STD but had multiple STDs in excess of what they reported. Only 46% of the patients provided accurate information on the follow-up questionnaire. Of the 99 girls who returned for follow-up, the inaccurate patients (10%) consisted of 9 who reported no visits for a pregnancy but had a pregnancy documented in their charts and 1 who underreported her number of pregnancies. Reliability analysis of the accuracy of STD and pregnancy self-report for our patients showed kappas ranging from 0.185 to 0.413 (slight and fair to moderate, respectively). Pearson correlation coefficients were 0.3107 and 0.4364 for STD and pregnancy, respectively.


CONCLUSIONS
Our patients' histories of visits for STDs and pregnancies are often not substantiated by review of their medical records. The reason for the inaccuracies in self-report of sexual behaviors is unclear. Further research in this area should be done. Physicians must confirm patient history concerning sexual practices through appropriate record review and medical evaluation.
