The study protocol was approved by the Ethics Committee of Dalin Tzuchi Hospital (No. B10002009) prior to the recruitment of participants. Researchers explained the purpose of study and its procedure to all participants. Signed informed consent was obtained after they understood and agreed to participate in this study. Thereafter, investigators applied an observer-blind approach for data collection. A trained interviewer, who was not familiar with the participants, was assigned to collect the participants' information on demographic and disease characteristics. All data were obtained at three time points: before DCMP (T0), three days after DCMP (T1), and three months after DCMP (T2). To reduce the dropout rate, researchers asked participants to return the hospital for the completion of assessments via phone reminders. However, participants were still given the option to withdraw from the study at any time without any penalty.
