Case 39. Linking Data Sets
Janice Spencer has collected data on how adolescents come to the attention of the juvenile justice system and what happens to them after their initial contact with the system. Her survey instrument and observations have focused on adolescents and their families and depends on self-reported data. Because her larger research agenda connects institutional agendas to the "fates" of adolescents labeled as having behavioral problems, she is also interested in how the police and other officials who come into contact with these adolescents respond. In addition to the study focused on kids and their families, she has been doing an evaluation study under contract for the city that follows police and judges and their decision-making on juvenile cases. Both of these projects have been approved by the relevant institutional review boards. After these are collected, Janice realizes that many of the same cases (i.e., the adolescents) were tracked in both studies and sees great potential in linking the two data sets. However, she realizes that her informed consent procedure did not anticipate that possibility and she becomes concerned about whether this is possible under agreements she has secured from both sets of respondents. The officials in the legal system, with whom she has discussed this issue, assure her that they will do whatever they can to make the data on the system available for research.
