One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such instrument was the Relationships protocol. This was a self-administered packet given to subjects in Cohorts 12, 15, and 18 to obtain information about dating, attitudes toward sex and having babies, and experience with sexual intercourse.
