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

Официальное название

A Brief and Blended Mindfulness-based Lifestyle Counselling Programme (B-Mindful-Life) for Behavioural Risk Modification Among Caregivers of People With Neurodegenerative Disorders: A Randomised Controlled Trial

Обзор

Over 80% of caregivers for individuals with neurodegenerative diseases (ND) engage in significant risk behaviors, particularly physical inactivity, which increases the risk of cardiometabolic diseases (CMD) by 30% and reduces life expectancy by 4-8 years. Despite the health benefits of maintaining healthy behaviors, awareness of behavioral risk management among healthcare professionals and the public is low, and research on this topic for ND caregivers is limited. Given that physical activity (PA) is the most prevalent modifiable risk factor, timely intervention is essential. International guidelines prioritize PA as a key strategy for caregiver health. However, existing PA interventions often struggle with low compliance due to the physical and emotional challenges caregivers face. Mindfulness-based lifestyle modification might help caregivers better manage physical discomfort, stress, and self-limiting beliefs, thereby supporting sustained PA by improving attentional regulation and psychological flexibility. The World Health Organization advocates for non-communicable disease (NCD) prevention through brief lifestyle interventions, such as ecological momentary interventions (EMI), which use mobile messaging (e.g., WhatsApp) to deliver personalized health content. This method is particularly valuable for caregivers who find it difficult to access traditional services due to their responsibilities. A pilot RCT was conducted to compare B-Mindful-Life to brief lifestyle education program in Chinese neurodegenerative disease caregivers, demonstrating promising acceptability, engagement, and effect for increasing PA (NCT06583018). Therefore, this full-power randomized clinical trial aims to rigorously examine its effectiveness and broader impact on this underserved population with several advancement: (i) broaden the population into all neurological disorder caregivers to test for the generalizability of the B-Mindful-Life program; (ii) conduct a 12-month follow-up to assess long-term effects of B-Mindful-Life intervention in real-life settings; (iii) modify outcome measures for targeted assessment. The primary outcome will measure the change in accelerometer-determined, 10-minute bout moderate-to-vigorous physical activity (MVPA) over a 7-day period from baseline to post-intervention.

Вмешательства

• Поведенческое In-Person Mindfulness-based Group Sessions
  The 3-hour group-based session in week 1 focuses on experiential mindfulness practices, and a booster session in week 5 further consolidates these mindfulness techniques, reinforces mindful, healthy lifestyle, and provides peer support. Participants will enhance their self-awareness of positive, neutral, and negative body sensations, feelings, and thoughts while engaging in healthy behaviors, particularly physical activity.
• Поведенческое Ecological Momentary Interventions (EMI)
  Participants will receive personalized instant messages with chat-based support throughout the 8-week intervention period. The message content is guided by existing international lifestyle modification guidelines and the Integrated Body-Mind-Spirit Model. The pre-set frequency of regular message delivery is five times per week. The schedule of message delivery will be personalized according to the participants' on-going needs/preferences over the intervention period. Chat-based support will be p
• Поведенческое In-person Lifestyle Education Session
  A 3-hour group-based session in week 1 focused on general education on lifestyle modification based on the HEARTS technical package as recommended by the WHO, and will only receive reminder messages for the two assessment follow-ups. No chat-based support will be provided.
• Поведенческое Activity Monitoring
  All participants will wear an accelerometer-based wristband activity tracker to monitor their physical activity in daily life.
