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.
