A brief, systematic and structured cognitive behavioural intervention (CBI) decreases anxiety and depression symptoms and improves quality of life in patients with end-stage renal disease (ESRD) who are being treated with haemodialysis. These benefits are not achieved when anxiety and depression symptoms are identified but not treated psychologically. This CBI consisted of cognitive restructuring of the distorted thoughts (perfectionism, catastrophic thinking, negative self-labelling, and dichotomous thinking) that are correlated with depression and anxiety symptoms and that can be assessed by a validated questionnaire designed for patients with ESRD. The handbooks that were developed for this study are structured and systematic. They could be valuable in supporting the efforts and participation of non-specialized health professionals in CBI such as nurses, physicians, social workers, and psychologists, raising the possibility of further application in a variety of clinical populations. Both the therapy and the client workbooks are available in Spanish upon request.
