CONSISTENCY OF ADOLESCENTS SELF-REPORT OF SEXUAL-BEHAVIOR IN A LONGITUDINAL-STUDY

This study examines three issues relevant to adolescent self-reported sexual behavior: the extent to which adolescents rescind reports of sexual intercourse, changes in reporting of lifetime sexual intercourse, and changes in reported age at first sexual intercourse. Data come from a three-year longitudinal study of health-compromising behaviors among a cohort a 758 rural adolescents. Students completed a self-administered questionnaire on health behaviors annually in eighth, ninth, and tenth grades. Findings show that 88.8% of students in eighth grade and 94.3% in ninth grade who reported having had sexual intercourse gave the same answer in a subsequent year. Approximately 15% of students reported fewer numbers of lifetime sexual intercourse experiences in tenth grade than they did in ninth grade. Age at first sexual intercourse was reported inconsistently by 67% of the students. Inconsistency rates differed by racial-gender groups, question sensitivity, and prior sexual experience.
