title: Psychological stress in sarcoidosis.
abstract: OBJECTIVE
  Sarcoidosis is a chronic illness associated with emotional and physical consequences which impact on quality of life. Although the impact of fatigue is well understood, emotional impacts of sarcoidosis are less commonly recognized and addressed in routine clinical practice. The purpose of this review is to highlight that sarcoidosis can result in considerable psychological distress.
  
  
  RESULTS
  Not only is there a high prevalence of depressive symptoms in sarcoidosis, but clinical depressive and anxiety disorders are more common than seen in the general population. Patients with sarcoidosis have perceptions and beliefs about their disease that may impact on their willingness to engage in recommended therapies. They may also exhibit a disordered perception of their disease and a personality profile of neuroticism. Understanding the minimally important clinical difference in the Fatigue Assessment Scale (FAS) and validation of the Sarcoidosis Health Questionnaire (SHQ) across different populations supports the use of these tools in routine clinical practice and clinical trials.
  
  
  CONCLUSIONS
  Understanding the global impact of sarcoidosis is important for patients and clinicians, and use of validated instruments, such as the SHQ and FAS, allows for more comprehensive assessment of the disease and the impact of any interventions.
