RESUMO
Purpose: Group mindfulness-based interventions are emerging as a promising, nonstigmatizing, and cost-effective strategy that may improve the well-being of individuals living with cancer. This study is a pilot pre-post mixed-method study to examine the feasibility, acceptability, and effects of an 8-week Mindfulness-based Cognitive Therapy group for Young Adults with Cancer (YA-MBCT). Methods: We approached young adults with cancer, who enrolled in YA-MBCT groups, offered at a large cancer hospital in Toronto, Ontario, Canada. Feasibility and acceptability were assessed through attendance rate and a postintervention satisfaction scale. Psychosocial outcomes were evaluated with a pre-post questionnaire package, with validated self-report measures, assessing depression, anxiety, perceived stress, quality of life, mindfulness, and self-compassion. Qualitative interviews were completed among a subset of participants to gain additional feedback. Results: Participants were 70 young adults with cancer, recruited from five YA-MBCT groups. Sixty participants (85%) attended a minimum of six of eight sessions, and overall satisfaction rates were high. All psychosocial outcomes demonstrated statistically significant changes (p < 0.01), with medium to large effect sizes (Cohen's d > 0.5). Qualitative interviews (n = 14) demonstrated overall positive views about the intervention, and provided insight into unique age-specific benefits, including reducing fear of cancer recurrence, improving body image, and creating a sense of belonging. Conclusion: The YA-MBCT is feasible and acceptable among young adults with cancer, with the potential to improve psychosocial outcomes. Our preliminary results should be replicated with larger studies with an active control group.
