Mindfulness has been described as a non-elaborative, non-judgmental, present-centred awareness in which each thought, feeling, or sensation is acknowledged and accepted. The aim of the present study was to systematically search and synthesise qualitative evidence of cancer patients’ attitudes to mindfulness. A systematic review of qualitative evidence was conducted following the SPICE framework. All cancers were included. Medline, Cinahl, Science Direct, O-Alster and New Bank were searched from the first available year to August 2016 using the search terms; wellbeing, mindfulness, qualitative. Two reviewers independently screened titles and abstracts; potentially relevant articles were retrieved and assessed independently by two reviewers. Data was extracted and quality assessed using Critical Appraisal Skills Programme (CASP) qualitative research checklist. In total 233 studies, conducted between 2005 and 2015 were identified with six included in the final analysis. Four themes were identified: Coping strategies developed through mindfulness course; Positive outcomes of mindful practice; Challenges with engaging in mindful practice; and Group identification and shared experience. The current evidence supports the view that mindfulness is an effective intervention to help people adjust to living with and beyond cancer, however more qualitative work is needed in this area.
