Technical Abstract: The ActiGraph activity monitor is a widely used method for assessing physical activity. Compliance with study procedures in critical. A common procedure is for the research team to meet with participants and demonstrate how and when to attach and remove the monitor and convey how many wear-days are needed. Scheduling a mutually convenient time to do this can be challenging and can have deleterious effects on the study timeline; therefore, other methods are needed. The Internet offers unique possibilities for reaching research participants. The purpose of this paper is to assess the feasibility of developing a study-specific video to communicate ActiGraph wear instructions.
