The Toledo Adolescent Relationships Study (TARS) Series explores the relationship qualities and the subjective meanings that motivate adolescent behavior. More specifically, this series seeks to examine the nature and meaning of adolescent relationship experiences (e.g. with family, peers, and dating partners) in an effort to discover how experiences associated with age, gender, race, and ethnicity influence the meaning of dating relationships. The series further investigates the relative impact of dating partners and peers on sexual behavior and contraceptive practices, as well as involvement in other problem behaviors that can contribute independently to sexual risk-taking. The longitudinal design of the Toledo Adolescent Relationships Study (TARS) includes a schedule of follow-up interviews occurring one, three, and five years after the initial interview. Four prior waves of data have been collected (2001, 2002, 2004, and 2006). Data were collected from adolescent respondents through structured in-home interviews utilizing laptop computers. In addition, the fifth wave, conducted in 2011 when the participants were young adults, builds on prior waves by adding quantitative and qualitative assessments of intimate partner violence (IPV). Wave 1 and Wave 2 are available through DSDR and can be applied for together. Wave 5 is available through NACJD and must be applied for separately. Please see the study homepages for more details on applying for restricted-use data access.
