Trajectories of Delinquency and the Juvenile Justice System Response: Collateral Consequences in Young Adulthood, Cook County, Illinois, 2011-2014

All participants of NJP were scheduled for follow-up interviews approximately 16 years (Follow-up thirteen) after baseline. A total of 389 participants interviewed at the end of the 16 year follow-up interview received the two additional modules that make up these data. Follow-up interviews for NJP were conducted face-to-face wherever the participant was living - in the community or in any correctional facility in Illinois - at the time their interview was due. However, community interviews were conducted by telephone if the participant live more than 2 hours away. Diagnostic modules were administered via PAPI or CAPI. Non-diagnostic modules were initially administered via PAPI; however beginning with NJP follow-up five, these modules were administered via CAPI. Due to the inclusion of additional variables, follow-up interviews were longer than baseline interviews and lasted 3 to 4 hours.
