One of the aims of this project is to assist researchers conducting long-term outcomes studies to maximize retention of research participants.
Victor Dinglas, MPH discusses (click image for the video) lessons learned regarding cohort retention including dispelling common myths in the field. He then discusses a Cohort Retention Toolbox (see menu below) which contains content developed based on a systematic review of the literature and semi-structured interviews of clinical researchers. Lastly, he discusses a case study that used many of these tools.
Below are tools we have available to help researchers maximize retention of research participants.
