title: Effects of repeated questionnaire administration in longitudinal studies of adolescent males' sexual behavior.
abstract: By comparing four similar groups of young adolescent males who completed questionnaires about their sexual behavior different numbers of times at various intervals, we explore the hypothesis that repeated questionnaire completion will affect sexual behavior. We find little support for the hypothesis even when the number of questionnaire administrations is very high.
