Trial outcomes
Primary outcomes
Feasibility of Mindfulness-based Intervention (MBI)
The feasibility of the MBI will be evaluated using the following criteria: recruitment and retention rates. The recruitment rate is ≥80% of subject recruitment of the study, time required to recruit to target sample size (≤4 months for recruiting 45 subjects; ≤9 months for recruiting 90 subjects), Adverse Effects reported by the subjects is ≤5% for the whole study, attendance rate is ≥75% of subjects attend each session of health education, reasons for drop out or withdrawal from the study record in number and percentage, program completion rate of the subject ≥70%.
Acceptability of the Mindfulness-based Intervention (MBI)
Acceptability will be assessed via a self-developed evaluation form completed after the 12-week MBI training. The form has three-part: Part 1 includes 4 questions on perceived benefits of MBI; Part 2 includes 8 questions on satisfaction with MBI class arrangement; Part 3 includes 3 questions for suggestions and feedbacks. Questions 1 to 12 (part 1 and 2) use a five-point Likert Scale (5 = "Strongly agree", 1 = "strongly not agree"). Question 10 assesses subjects' willingness to continue MBI practice. Questions 13 and 15 (part 3) are open-ended, collecting "other comments" and suggestions for improving the MBI class, respectively.
Secondary outcomes
Loneliness
The Chinese version of the Revised University of California Los Angeles (R-UCLA) 3-item Loneliness Short Scale used to measure subjective feelings of loneliness. This 3-item, 4-point Likert scale (0 = "never", 3 = "always") yields scores from 0 to 9, with higher scores indicating greater perceived loneliness. Cronbach's for the Chinese R-UCLA is 0.87.
Sleep quality
The Chinese Pittsburgh Sleep Quality Index (PSQI) assesses sleep quality over past month across seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, sleep medication, and daytime dysfunctions. This 19-item, 4-point Likert scale (0 = "no difficulty, 3 = "severe difficulty") generates scores from 0 to 21, with ≥8 indicates sleep disturbance. Cronbach's α for the Chinese PSQI is 0.79.
Stress level
The Chinese 10-item Perceived Stress Scale (PSS-10) measures stress using a 5-point Likert scale (0 = "never", 4 = "very often") generate score from 0 to 40. It includes four positive items assessing stress adaptation and six negative items evaluating negative affective reactions and lack of control. Higher scores indicate greater stress. Cronbach's α for PSS-10 is 0.83.
Participants' Quality of Life
The EuroQol 5-Dimension 5-Level (EQ-5D-5L) HK evaluates QoL across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five levels (no problem to extreme problems). A utility score (-1 to 1; \<1 = "worse than death", 0 = "death", 1 = "full health") is derived for clinical and economic appraisal.
