Psychological adjustment to chronic disease Denise de Ridder, Rinie Geenen, Roeline Kuijer, Henriët van MiddendorpLancet 2008; 372: 246–55 This Review discusses physiological, emotional, behavioural, and cognitive aspects of psychological adjustment to Department of Clinical & Health chronic illness. Reviewing the reports of the past decade, we identify four innovative and promising themes that are Psychology, Utrecht University, relevant for understanding and explaining psychological adjustment. In particular, the emphasis on the reasons why The Netherlands Research people fail to achieve a healthy adjustment has shifted to the identifi cation of factors that help patients make that Institute for Psychology & adjustment. To promote psychological adjustment, patients should remain as active as is reasonably possible, Health, Utrecht, Netherlands acknowledge and express their emotions in a way that allows them to take control of their lives, engage in self-management, and try to focus on potential positive outcomes of their illness. Patients who can use these strategies have the best chance of successfully adjusting to the challenges posed by a chronic illness. Introduction
