The Cardiac Depression Scale (CDS) was developed for the specific purpose of providing a valid and reliable instrument to measure depression in cardiac patients. The CDS is the only measure for depression derived from responses of cardiac patients. It offers a more responsive and sensitive alternative to other measures that are not always suitable for cardiac patients because they have been developed and validated in non-cardiac populations. The CDS is a 26 item questionnaire, each item requiring a response on a Likert scale from 1 (‘Strongly disagree’) to 7 (‘Strongly agree’), the scale being tagged at each end with an explanatory phrase. | The Cardiac Depression Scale (CDS) was developed for the specific purpose of providing a valid and reliable instrument to measure [[depression]] in [[Cardiovascular Disease|cardiac]] patients.

Objective [edit | edit source]
The Cardiac Depression Scale (CDS) was developed for the specific purpose of providing a valid and reliable instrument to measure depression in cardiac patients. The CDS is the only measure for depression derived from responses of cardiac patients. It offers a more responsive and sensitive alternative to other measures that are not always suitable for cardiac patients because they have been developed and validated in non-cardiac populations. The CDS is a 26 item questionnaire, each item requiring a response on a Likert scale from 1 (‘Strongly disagree’) to 7 (‘Strongly agree’), the scale being tagged at each end with an explanatory phrase.
Intended Population[edit | edit source]
The target population is cardiac patients with diagnosed cardiac diseases. The scale has been tested on following population
- Adult cardiac disease patient examples includes: coronary artery disease; heart failure, post myocardial infarction, cardiac valve defects, arrythmias, cardiomyopathies.
Method of Use [edit | edit source]
Equipment Required: Test paper and pencil
General Instructions: The test requires no formal training and takes only 5 minutes to administer.The scale is of self report type, so patient is properly instructed to fill the scale ensuring proper scoring.
The Scale: The questionnaire consists of a number of statements about the way patient feel at present.
Next to each statement there is a rating scale from 1 to 7 for patient to indicate how much you agree or disagree with the statement.
- Strongly disagree 1 2 3 4 5 6 7 Strongly agree
- The scale has 26 questions or statements for which patient marks from 1 to 7 and the final reading is taken.
Reliability and Validity: Whilst having 97% sensitivity and 85% specificity for diagnosing major depression, it also assesses the range of less severe ‘reactive’ depression. The interrater and the reliability has not been established. In a validation study done in UK for CDS, a battery of questionnaires (the Medical Outcomes Study Short-Form 36 [SF-36] Health Survey, the Beck Depression Inventory [BDI], the Hospital Anxiety and Depression Scale [HADS] and the Cardiac Depression Scale [CDS]) were used to find out the reliability of CDS.The results demonstrated high internal reliability (Cronbach's alpha = 0.93) and an acceptable test-retest reliability (0.79). Concurrent validation against the SF-36, BDI and HADS demonstrated strong correlations. It was used in men recovering from CABG surgery. The result of showed Excellent correlation with Beck Depression Inventory (r = 0.751, 0.787, 0.737, 0.819) at baseline, 6, 12, and 36 weeks respectively.
Conclusion[edit | edit source]
The Cardiac Depression Scale is under copyright. Further information can be obtained from Dr. Samia Toukhsati at [email protected] or Professor David Hare at [email protected]
