title: Depression and anxiety in patients with coronary artery disease, measured by means of self-report measures and clinician-rated instrument.
abstract: BACKGROUND
  The presence of depression symptomatology significantly deteriorates the prognosis for the patient. There are many instruments developed to measure depression and anxiety in clinical trials; however, the suitability of the specific scale for screening these disorders in cardiovascular patients is debatable. The aim of current study is to verify which of the major assessment instruments is the most relevant for the screening evaluation of depression and anxiety in patients with cardiovascular system diseases.
  
  
  OBJECTIVE
  The sample studied consisted of 120 patients with stable coronary artery disease (CAD). They did not display serious psychiatric or somatic disorders.
  
  
  METHODS
  To assess depressive and anxiety symptoms we used self-reporting measures (BDI-II, HADS, SSAI/STAI, and PHQ), the results of which were compared to results obtained on the basis of a clinician-rating instrument (HRSD).
  
  
  RESULTS
  We found that depressive symptoms assessed on the basis of HRSD, BDI-II, and PHQ-9 were equivalent in results, while the results obtained in HADS-D were significantly lower. Anxiety symptoms were found at approximate levels in HADS, SSAI, and GAD-7. The assessment of somatic symptoms in patients with CAD indicates that 87.5% of the subjects reported somatic symptoms of various intensity.
  
  
  CONCLUSIONS
  Screening assessment of depression in patients with CAD gives different results depending on the tool used. We found that HADS significantly underestimates the percentage of patients with symptoms of depression in patients with CAD. Assessing anxiety symptoms with the aid of HADS gave outcomes close to the results gained by use of other tools.
