Mindfulness Meditation and Qigong for Colorectal Cancer Survivors

Starting From the Mind or the Body in Mind-Body Intervention: A Randomized Controlled Trial on Comparative Effectiveness of Mindfulness Meditation and Qigong on Psychophysiological Outcomes in Colorectal Cancer Patients

Colorectal cancer imposes threats to patients' well-being. Although most physical symptoms can be managed by medication, psychosocial stressors may complicate survival and hamper quality of life. Mindfulness and Qigong, two kinds of mind-body exercise rooted in Eastern health philosophy, has been found effective in symptoms management, improving mental health, and reducing stress. With these potential benefits, a randomized controlled trial (RCT) is planned to investigate the comparative effectiveness of mindfulness and Baduanjin intervention on the bio-psychosocial wellbeing of people with colorectal cancer. A 3-arm RCT with waitlist control design will be used in this study. One hundred eighty-nine participants will be randomized into (i) Mindfulness, (ii) Baduanjin, or (iii) waitlist control groups. Participants in both the Baduanjin and mindfulness groups will receive 8-weeks of specific intervention. All three groups will undergo four assessment phases: (i) at baseline, (ii) at 4-week, (iii) at 8-week (post-intervention), and (iv) 6-month post-intervention (maintenance). All participants will be assessed in terms of cancer-related symptoms and symptom distress, mental health status, quality of life, stress level based on physiological marker. Based on prior research studies, participants in both the mindfulness and Baduanjn intervention group are expected to have better symptoms management, lower stress level, better mental health, and higher level of quality of life than the control group. This study contributes to better understanding on the common and unique effectiveness of mindfulness and Baduanjin qigong, as such patients and qualified healthcare professionals can select or provide practices which will produce maximum benefits, satisfaction, adherence, and sustainability.

Study Overview

• Status: Unknown
• Conditions: Colorectal Cancer
• Intervention / Treatment: Behavioral: Baduanjin qigong; Behavioral: Mindfulness meditation

Detailed Description

Colorectal cancer is one of the most common forms of cancer. Lifestyle modification and development of self-regulatory and self-care skills for maintaining psychological and physical well-being are especially important for recurrence prevention and long-term illness management. Mind-body practices are popular among cancer patients for being non-pharmacological, holistically beneficial, in addition to its feasibility for sustainable self-practice and self-care. Despite the popularity of practising qigong and mindfulness meditation among local patients, a systematic study on their effectiveness for cancer patients has yet to be conducted.

Qigong and mindfulness meditation represent two distinct forms of mind-body practices: dynamic and static. With both approaches attending to the breath, Qigong relies on physical exertion to arrive at mental and psychological changes while mindfulness meditation begins at mental level but can also impact physical health. Yet current knowledge on mind-body practices tells little about these contrasting approaches. Hence, this study not only aims to provide evidence for the psychophysiological effectiveness of qigong and mindfulness meditation for colorectal cancer patients, but also elucidate how these two fundamentally contrasting approaches differ in psychophysiological outcomes, rebalancing of dysfunctional cortisol rhythm, and affect long-term practice compliance.

Adopting a 3-arm randomized controlled trial design, this study will first independently study the effectiveness of Baduanjin qigong and Mindfulness meditation for Chinese colorectal cancer patients compared to controls on cancer-related symptoms and symptom distress, mental health, quality of life, biomarkers and mindfulness level. Another main objective is to examine the commonalities and differential effectiveness between a movement-based (Baduanjin qigong) and a mind-based (Mindfulness meditation) practice on the above outcomes, magnitude and pace of change, and the extended compliance throughout the 8-month study. A final objective is to examine the relationships among physical, psychological, and psychophysical variables and how these interactions between the mind and body. This study envisions advancing relationships change across the time.

189 Chinese-speaking patients with colorectal cancer will be recruited from local hospital and community organizations, then randomized into an 8-week (90-min/week) (i) Baduanjin qigong intervention, (ii) Mindfulness meditation intervention and (iii) No-intervention waitlist control. Participants will be assessed on 4 time points at (i) baseline prior randomization, (ii) mid-intervention (4th week), (iii) post-intervention (8th week) and (iv) 6 months post-intervention.

The measurement of both physiological and psychological outcomes will offer a comprehensive understanding on the mental and bodily changes after each intervention and their maintenance. Results will further support the reciprocal evidence-based mind-body practices which can be easily learned, self-practiced and incorporated into patients' lifestyles.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Intervention: Baduanjin qigong; This arm of participants will be receiving the Baduajin qigong intervention.	Behavioral: Baduanjin qigong; The intervention consists of eight sequential forms of movements which is practiced with guidance on rhythmic breathing and mindful awareness. Each cycle of the eight movements requires 10 to 15 minutes for completion. Four cycles will be practiced in each session with short breaks arranged between them.
EXPERIMENTAL: Intervention: Mindfulness meditation; This arm of participants will be receiving the Mindfulness meditation intervention.	Behavioral: Mindfulness meditation; The intervention is developed based on the core components of the established Mindfulness-Based Stress Reduction and the Mindful Self-Compassion program with adaptation for local practice. The focus of the group is to nurture mindful awareness, acceptance, and self-compassion. The group sessions are composed of a combination of mindfulness-based practice, relaxation, and yoga exercise. The basic philosophy of this intervention is the emphasis of the nurturing of self-kindness attitude, and non-attachment attitude towards inter-personal connectedness and letting go of self-criticism, need for control, and defensive separation in times of adversity. Short breaks will be arranged between each practice.
NO_INTERVENTION: Control; This arm of participants will not receive any intervention and are allocated as a Wait-list Control group.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
