Limitations
RECRUITMENT
One limitation of this study was that the recruitment of participants was challenging. First, it was difficult to convince medical students to join a 5-month study. In addition, the recruitment phase was interrupted by the COVID-19 pandemic, which limited our ability to reach and meet with potential participants. The awareness and knowledge about mindfulness in the region pose another challenge for recruiting subjects easily. Clearly the drop-out number in the MBSR group was higher than the waitlist, which increases the likelihood of type 2 error, and could affect the balance of the baseline characteristics between the study groups. In addition, we didn’t assess the reasons behind the low number of participants who completed the whole program sessions in the MBSR group.
