I don't mind depositing the baseline study from my longitudinal data system, but is it possible to delay release of subsequent waves of data?
The utility of longitudinal studies lies primarily in the follow-up embedded in the research design. While the baseline data will be valuable in the short run, NAHDAP will work with depositors on a time frame for acquisition and release of the subsequent waves of data. Without a reasonable time frame, baseline studies will not be acquired for the NAHDAP. Depositors can work with NAHDAP staff to develop a method for acquiring and releasing the additional waves under a delayed-dissemination agreement. These agreements allow the subsequent waves to be acquired and prepared but not released for secondary analysis until the appropriate time.
