Abstract

Retaining study participants over time is essential for longitudinal studies to prevent selection bias and to achieve their long-term goals. The present paper examines the extent to which participants can be retained in a 30-year longitudinal study when a multi-pronged approach is employed. The paper specifically describes the approach that was used to locate and interview participants of the Chicago Longitudinal Study (CLS), three decades after the study began. The CLS is a prospective cohort investigation that examines the effects of the Child-Parent Center (CPC) program, a school-based intervention for low-income children from preschool through 3
