This study examined the accuracy of two retrospective methods and assessment intervals for recall of sexual behavior and assessed predictors of recall accuracy. Using a 2 [mode: audio-computer assisted self-interview (ACASI) vs. self-administered questionnaire (SAQ)] by 2 (frequency: monthly vs. quarterly) design, young women (N =102) were randomly assigned to one of four conditions. Participants completed baseline measures, monitored their behavior with a daily diary, and returned monthly (or quarterly) for assessments. A mixed pattern of accuracy between the four assessment methods was identified. Monthly assessments yielded more accurate recall for protected and unprotected vaginal sex but quarterly assessments yielded more accurate recall for unprotected oral sex. Mode differences were not strong, and hypothesized predictors of accuracy tended not to be associated with recall accuracy. Choice of assessment mode and frequency should be based upon the research question(s), population, resources, and context in which data collection will occur.
