Chronic heart failure is a common and a serious condition. Research has shown that chronic heart failure has been associated with detrimental effects on wellbeing. Coping effectiveness training (CET) has been applied for patients with heart failure to improve stress appraisal and stress management skills. The aim of this study was to explore the experience of participating in CET for patients with heart failure one year after completion. Eleven patients were interviewed. The study adheres to the SRQR guidelines. A thematic analysis generated three themes: rewarding but challenging to meet other people with heart failure; improved conditions to cope with stress; and not relevant to me. Implications for further development of the intervention were to include existential aspects, recognize comorbidities, test follow-up sessions and apply a codesign.
