How to access CHILD Cohort Study data
1. Contact the NCC: If you are interested in collaborating on a project and accessing CHILD Cohort Study data, contact the Study’s National Coordinating Centre (NCC) to discuss your needs before initiating a formal request.
2. Submit a Study Concept Proposal: To access CHILD Cohort Study data for a collaborative project, the requesting individual or group of investigators must first submit a completed Study Concept Proposal to the Study Director at the NCC, for review by the CHILD Executive.
3. Submit a Data Request: If the Study Concept Proposal is approved by the CHILD Executive, the requesting individual or group of investigators must then submit a completed Data Request to the Study Director at the NCC. The request must specify:
- The person making the request
- The date of the request
- The purpose of the request
- The data being requested, as precisely as possible; e.g., specific questions, questionnaires, objective sample data
- The population for whom data are requested; e.g., single site, all sites, Vanguard or General study
- The use that will be made of the data, including the statistical approach to analysis where appropriate
- How the data should be best formatted
- When the data are required
The request for data will be reviewed at the NCC, and a decision made in a timely manner where there are no issues regarding ownership, conflicting requests, or suggestions of ‘data-mining’ raising concern.
4. Complete a MITA: If the request is approved, before it can be fulfilled a Material and Information Transfer Agreement (MITA) must be established between McMaster University (the provider institution) and the requester’s institution, and signed by authorised representatives of both institutions as well as the Study Director and the recipient scientist.
With the MITA in place and the request approved, the Study’s Data Manager will clarify any technical uncertainties in the request and the formatting of the outputs, and will provide the data within a reasonable time frame to the requesting investigator(s).
5. Provide the resulting data set to CHILD: Data analyzed by investigators remains the property of the CHILD Cohort Study, and investigators are required to provide the NCC with documentation of derived data arising from analyses conducted using CHILD data. It is not sufficient to provide the NCC with the final publication emerging from data analyses; a full data set, including derived variables, must be provided.
6. Submit a Manuscript Proposal: If the study’s results are being considered for publication, the requesting individual or group of investigators must first submit to the NCC a Manuscript Proposal for review by the CHILD Cohort Study’s Publication Committee.
