Depression is common in adult patients with cardiac disease, with approximately 1 in 3 individuals who survive an acute myocardial infarction having some form of depression.1
Cardiac patients with depression are less likely to acknowledge their condition and have decreased motivation to follow recommended treatments, negatively affecting their recovery and overall quality of life.1
The Cardiac Depression Scale (CDS) indexes the full spectrum of depressive symptoms in adults with cardiac disease.2
The CDS is easy to administer, requiring only pencil and paper, and no special training is necessary.2
The self-report test includes 26 items, with scores ranging from strongly disagree (1) to strongly agree (7) across a 7-point Likert scale. Items are summed for a total score ranging from a minimum of 26 to a maximum of 182; a higher score reflects more severe depressive symptoms.3
The CDS has excellent test-retest reliability and internal consistency, and for scores ≥95 excellent sensitivity and specificity.3., 4., 5.
Early recognition and consequently early intervention has the potential to save lives; therefore, application of the CDS can identify patients with cardiac disease who may require further assessment and intervention.
This Rehabilitation Measures Database summary provides a review of the psychometric properties of the CDS in adult cardiac patients. A full review of the CDS as well as reviews of over 100 other instruments can be found at www.rehabmeasures.org
