RECRUITMENT
Our study had a few limitations. First, this study uses data collected as part of the recruitment processes for an ongoing trial. Thus, there is a possibility that the estimates of reach, clicks, and consent may change when our study is completed, although this is unlikely since our findings are consistent with previously published studies. Additionally, although there is an assumption that patients consider remote interventions more favorably as a matter of convenience, we did not access participants’ preference to either telehealth or face-to-face trials. Second, it is not known how generalizable our study findings are to geographical areas outside the United States or studies that are more controlled or have more stringent exclusion criteria. Finally, we did not aim to compare Facebook recruitment with other social media, such as Instagram and Twitter, or with traditional recruitment methods (eg, flyers, print and broadcast media, and word of mouth) since this was beyond the scope of our study.
