Procedure
This parallel-group randomized clinical study was conducted in Chongqing, China, from October 2021 to January 2022. Subjects were recruited through advertisements that included the study design, overall structure of the intervention program, themes and duration of each session, and potential benefits and risks. The applicants interested in participating were asked to complete the online eligibility assessment (using the Questionnaire Star platform). A total of 89 emergency nurses applied, and 74 of them were enrolled in the study. All participants provided informed written consent to participate in this study. Participants were randomly assigned to either the intervention group (n=38) or the comparison group of waiting lists (n=36) using the random number calculation procedure (www.random.org) by a researcher who was not associated with the current study. Figure 1 illustrates the flow of participants through the study.
The intervention group received MBSR training once a week for eight weeks, while the comparison group received no intervention. However, they were offered the same training upon completion of the study if they wished. The author evaluated the outcomes without knowledge of the treatment condition. They served as an independent evaluator at the beginning of the study, after the intervention (week 9) , and at the 1-month follow-up (week 13).
