Acceptability and preliminary test of efficacy of the Mind programme in women with breast cancer: An acceptance, mindfulness, and compassion-based intervention

Abstract

Although there is some evidence on the efficacy of mindfulness-based interventions in improving health and psychological outcomes in women with breast cancer, further research is needed to understand these findings’ clinical significance. Furthermore, Acceptance and Commitment Therapy (ACT) intervention studies on breast cancer are scarce, and no compassion-based intervention has been tested for cancer patients. Given the complementarity and compatibility of mindfulness practice, ACT, and Compassion Focused Therapy, the current study combined these approaches to develop an integrative intervention specifically adapted to cancer patients, the Mind programme. Participants were recruited at the Radiotherapy Service of the Coimbra University Hospital (CHUC) and were assigned to one of two groups: the experimental group (Treatment As Usual + Mind Programme (8 weekly sessions and homework assignments) – n = 15) and the control group (Treatment As Usual – n = 17). There was a 100% retention on the experimental group, during the intervention. The effect size for psychological health (g = 0.79) was particularly noteworthy, suggesting that the intervention presented benefits that are comparable to mindfulness only-based interventions. The experimental group also improved on physical health (g = 0.16), quality of social relationships (g = 0.42), depression symptoms (g = −0.42), and stress (g = −0.32). Participants reported it was important for them to take part in the programme, and that it improved the way they deal with difficulties. Results indicate that the Mind programme may be a useful complement to the medical treatment of breast cancer and support the combination of acceptance, mindfulness, and compassion-based components in this context. Having an accessible and integrative psychological programme for people with cancer may significantly help improving quality of life and mental health in this population. Further implications are discussed.
