Patients recruited from the Department of Respiratory Medicine, Aarhus University Hospital, will be randomized to participate in either an 8-week MBCT program as an add-on to the already established pulmonary rehabilitation program (intervention group) or pulmonary rehabilitation only (treatment-as-usual). Questionnaires assessing outcomes, mediators and moderators will be completed before, during, and after the intervention as well as at a 3 and 6 mo. follow-up.
