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 3rd grade. The original CLS sample included a complete cohort of 1539 children who were born in low-income areas in 1979–1980 and attended kindergarten in 1985–1986 at Chicago Public Schools. The CLS conducted a follow-up survey when participants were approximately age 35. After relatively slow initial progress, CLS researchers developed a comprehensive strategy to locate and interview participants, including: (a) adoption of detailed, manualized tracking protocol, (b) utilization of multiple search platforms, ranging from public search engines to social media, (c) assistance from state correctional facilities, and (d) neighborhood ...
