Cohort Studies

The CHSS Center for Research and Quality conducts multi-institutional, longitudinal research. Study participants are enrolled at different institutions across the United States and Canada, and the information is sent to the CHSS Center for Research and Quality, which is located at The Hospital for Sick Children (SickKids) in Toronto, Canada. The Center for Research and Quality will send annual follow-up questionnaires to all study participants, even if the study has been closed to enrollment.

This section contains all the documents you will need to complete your Institutional Review Board (IRB) or Research Ethics Board (REB) submissions.

The following cohorts are open to enrollment. Please navigate to each cohort page to find documents related to each of these studies.

Each institution receives their own institution's Research Activity Report semi-annually, or at any time if requested. Please contact us for more information on Research Activity Report.
