Despite the importance of reliable self-reported sexual information for research on sexuality and sexual health, research has not examined reliability of information provided by gay, lesbian, and bisexual (GLB) youths. Test–retest reliability of self-reported sexual behaviors, sexual orientation, sexual identity, and psychosexual developmental milestones was examined among an ethnically diverse sample of 64 self-identified GLB youths. Two face-to-face interviews were conducted approximately 2 weeks apart using the Sexual Risk Behavior Assessment Schedule for Homosexual Youths (SERBAS-Y-HM). Overall, the mean of the test–retest reliability coefficients was substantial for 6 of the 7 domains: lifetime sexual behaviors (M=.89), sexual behavior in the past 3 months (M=.96), unprotected sexual behavior in the past 3 months (M=.93), sexual identity (κ=.89), sexual orientation (M=.82), and ages of various psychosexual developmental milestones (M=.77). Inconsistent reliability was found for reports of sexual behaviors while using substances. A small number of gender differences emerged, with lower reliability among female youths in the lifetime number of same-sex partners. The overall findings suggest that a wide range of self-reported sexual information can be reliably assessed among GLB youths by means of interviewer-administered questionnaires, such as the SERBAS-Y-HM.

Notes
A fourth item assessing sexual orientation with respect to past sexual behaviors (consistent with the Kinsey definition of sexual orientation was also assessed. However, because it was interviewer-rated, not self-reported, it was not included in this analysis of the reliability of self-reported sexuality.
Examination of the data did not indicate the existence of any outliers, but rather, a pattern of inconsistency characterizing a large number of female youths. For other low reliability coefficients, the potential impact of outliers also was examined, but not found.
