Outcomes
RECRUITMENT
According to the MRC framework, the feasibility stage includes testing procedures for acceptability and estimating the recruitment and response rates. Therefore, this study estimated the intervention program from the following aspects: (1) rates of recruitment, (2) retention rate in the study, (3) success rate of sessions participation, (4) acceptability of the intervention: A 8-item satisfaction questionnaire was developed to measure participants’ satisfaction with the intervention. Participants in the intervention group were asked to rank the satisfaction of each item on a Likert 5-point scale, ranging from 1 (not at all agree) to 5 (strongly agree). The satisfaction rate was calculated using the percentage of participants who rated an item as 4 or 5 points. The Cronbach’s α of the 8-item satisfaction questionnaire was 0.914 in the present study.
