Mindfulness-based Lifestyle Modification Programme for Caregivers of People With Neurological Disorders

For caregivers only, measured by the accelerometer-based wristband activity tracker. The data will be considered valid if the participants wear the activity tracker for ≥10 hours/day for ≥5 days over a 7-day period.

For both caregivers and care recipients, measured by EuroQol 5-dimension 5-level questionnaire (EQ-5D-5L). The questionnaire comprises two main components: a description of health status across 5 dimensions (mobility, self-care, usual activities, pain or discomfort, and anxiety or depression), and a numeric value representing the overall health status perceived by the respondents (EQ-VAS). Each dimension is rated from 0 (no problems) to 4 (extreme problems). The scores across the 5 dimensions will be transformed into a utility score based on a validated EQ-5D-5L value set for the Chinese population, with a higher utility score indicating a better health state. The EQ-VAS records an individual's self-rated health on a numeric analogue visual scale, ranging from 0 (the worst health) to 100 (the best health).

For caregivers only, measured by International Physical Activity Questionnaire - Short Form. Continuous scores will be calculated according to the standard scoring protocol, which transforms various physical activities into metabolic equivalent (MET)-minutes/week. A higher MET-minutes/week indicates a higher level of physical activity Based on the duration of different physical activities and the calculated MET-minutes/week, participants can also be classified into three categories: Low, Moderate, and High levels of physical activity.

For caregivers only, measured by the Chinese DASS-21 using a one-week recall period, which was developed to measure three related and clinically significant negative emotional states of depression, anxiety and stress. Each item is rated on a 0-3 scale (0="Did not apply to me at all" to 3="Applied to me very much or most of the time"). The score of each subscale ranges from 0-42 and the total score ranges from 0-126, with higher score indicating greater self-reported levels of depression, anxiety and stress.

For caregivers only, measured by the 12-item Zarit Burden Interview - Short Version (ZBI-SV). Each item is rated on a 0-4 scale (0=Never, 4=Very Often). The total score ranges from 0-48. Higher score indicates heavier caregiver burden. Three domains of ZBI-SV perceived role strain, self-criticism, and negative emotion will also be assessed

For caregivers only, measured by the Chinese Positive Aspects of Caregiving Scale (C-PACS). Each item is rated on 1-5 scale (1= disagree a lot; 5 = agree a lot). The total score ranges from 10-50. Higher score indicates more positive appraisal towards caregiving. In addition, two domains of the C-PACS, namely enriching life and affirming self will be assessed

For caregivers only, measured by the validated Chinese 32-item Multidimensional Assessment of Interoceptive Awareness (MAIA). Each item is rated on a a 0-5 scale (0=never, 5=always). Higher score indicates higher level of mindfulness. In addition, eight domains of the MAIA, namely noticing, not-distracting, not-worrying, attention regulation, emotional awareness, self-regulation, body listening and trusting will be assessed.

For caregivers only, measured by 20-item Self-Care Inventory (SCI). Each item is rated on a 1 to 5 scale (1=Never, 5=Always). 3 domains of the SCI, namely self-care maintenance, self-care monitoring, and self-care management will be assessed. The score of each domain is derived from the raw summative score using the scoring algorithm proposed by the scale developer, which ranges from 0 to 100. A higher score on the SCI indicates better engagement in self-care in the corresponding domain.

For caregivers only, measured by the 10-item Self-Care Self-Efficacy Scale (SCSES). Each item is rated on a 1 to 5 scale (1=No Confident, 5=Extremely Confident). The total score ranges from 10-50. Higher score in SCSES indicates higher level of self-care efficacy.

For caregivers only, measured using a validated electroencephalogram-based headband tracker. Participants will wear the headband with assistance from the outcome assessor before following a standardized audio-guided protocol. Attention and meditation levels will be assessed using a 0-100 rating scale, where a higher score indicates increased focused attention and meditation status, respectively.

For care recipients only, measured by the 10-item Palliative care Outcome Scale (POS). The 10 items assess physical symptoms, emotional, psychosocial and spiritual needs, provision of information and practical concerns. Each item is rated on a 0 - 4 scale (0=No burden, 4=Overwhelming problems). The total score ranges from 0-40. Higher score indicates greater unmet support care needs.

For the experimental group participants, a semi-structured individual interview will be conducted to explore their experiences and identify facilitators and barriers to the implementation and acceptability of the intervention.
