Title of Assessment

Cardiac Depression Scale 

Acronym

Instrument Reviewer(s)

Initally reviewed by Kristine Flais in November 2013.

Summary Date

1/3/2014 

Purpose

To measure depression in adult cardiac patients

Description

  • A self-report 26-item, seven-point Likert-type scale ranging from strongly disagree (1) to strongly agree (7)
  • Minimum score of 26 and maximum score of 182
  • Items 2, 4, 12, 15, 19, 20, and 23 are reversed scored (1 = 7, 2 = 6, 3 = 5, 4 = 4 ,5 = 3, 6 = 2, 7 = 1)
  • A total higher score reflects more severe depressive symptoms

Populations Tested

Cut-Off Scores

Adult cardiac patients:

(Shi et al, 2010; n = 215)

  • A cut off score of > 95 had 97% sensitivity and 85% specificity for major depression as indexed using the Mini-International Neuropsychiatric Interview

(Wise et al, 2006; n = 627; mean age= 58.7 (13.0))

  • Score >100 indicates severe depression with 88% sensitivity and 84% specificity
  • Score of 90 indicates mild to moderate depression with 84% sensitivity and 78% specificity

Normative Data

Not established

Test-retest Reliability

Adult cardiac patients:

(Birks et al, 2004; n = 396; mean age= 67(9))

  • Excellent test-retest reliability (r = 0.79)

Interrater/Intrarater Reliability

Not established

Internal Consistency

Adult cardiac patients:

(Birks et al, 2004)

  • Excellent internal consistency (Cronbach’s alpha = 0.93)

(Hare and Davis, 1996; n = 246; mean age= 59.3 (14.1))

  • Excellent internal consistency (Cronbach’s alpha = 0.90)

(King et al, 2009; n = 120; mean age = 63.54 (10.16); mean post-operative days 6.58 (3.53); status-post first time coronary artery bypass graft surgery data collected at hospital discharge, 6, 12, and 36 weeks post-operatively; males only)

  • Excellent internal consistency (Cronbach’s alpha = 0.86 - 0.91)

(Kiropoulos et al, 2012; n = 152; mean age = 70.34 (8.18); 3.5 months after cardiac hospitalization)

  • Excellent internal consistency (Cronbach’s alpha = 0.91)

(Wise et al, 2006)

  • Excellent internal consistency (Cronbach’s alpha = 0.92)

Criterion Validity (Predictive/Concurrent)

Adult cardiac patients:

(Benedetto et al, 2006; n = 81; mean age=57 (12); 2 weeks post acute coronary syndrome)

  • Excellent correlation with Beck Depression Inventory-II (r = 0.69)

(Birks et al, 2004)

  • Excellent correlation with Beck Depression Inventory (r = 0.78)
  • Excellent correlation with anxiety and depression subscales of the Hospital Anxiety and Depression Scale (r = 0.751 and r = 0.770, respectively)

(Hare and Davis, 1996)

  • Excellent correlation with Beck Depression Inventory (r = 0.73)

(King et al, 2009)

  • Excellent correlation with Beck Depression Inventory (r = 0.751, 0.787, 0.737, 0.819) at baseline, 6, 12, and 36 weeks respectively

(Kiropoulos et al, 2012)

  • Excellent correlation with Beck Depression Inventory-II (r = 0.65)
  • Excellent correlation with State Trait Anxiety Inventory (r = 0.61)

(Wise et al, 2006)

  • Excellent correlation with Geriatric Depression Scale-Short From (r = 0.77)

Considerations

The Cardiac Depression Scale is under copyright. Further information can be obtained from Dr. Samia Toukhsati at samia.toukhsati@austing.org.au or Professor David Hare at david.hare@austin.org.au
  • The test indexes the full spectrum of depressive symptoms in adult cardiac disease patients
  • The test has excellent reliability, sensitivity and specificity properties
  • The test is easy to administer and no special training is necessary
  • A copy of the test is not readily available which may make it difficult to utilize
  • No standard error of measurement or normative data is available
