Insights
The six-item Hamilton Depression subscale (HDSS) is a valid tool for assessing depression in chronic obstructive pulmonary disease (COPD) patients. This finding supports its use in clinical practice for this population.
Area of Science:
- Pulmonary Medicine
- Psychiatry
- Clinical Psychology
Background:
- Depression is a common comorbidity in patients with chronic obstructive pulmonary disease (COPD).
- Accurate assessment of depression is crucial for effective management of COPD patients.
- The validity of standard depression scales in COPD populations requires evaluation.
Purpose of the Study:
- To assess the validity of the Hamilton Depression Scale (HDS) in patients with moderate to severe COPD.
- To determine if the six-item Hamilton Depression subscale (HDSS) is a reliable measure for depression in this cohort.
Main Methods:
- 49 patients with moderate to severe COPD were assessed using ICD-10 criteria for depression.
- 46 patients were evaluated with the 17-item HDS and the six-item HDSS.
- Internal and external validity were examined using factor analysis, Cronbach's alpha, Loevinger's homogeneity coefficient, correlation, and ROC curves.
Main Results:
- 47% of COPD patients met ICD-10 criteria for depression.
- The HDSS demonstrated good internal validity, unlike the full HDS.
- The HDSS also showed acceptable external validity in this patient group.
Conclusions:
- The six-item Hamilton Depression subscale (HDSS) is recommended as a suitable depression rating scale for COPD patients.
- The HDSS provides a valid and reliable method for screening depression in individuals with COPD.
Objective:
To estimate the validity of the Hamilton Depression Scale (HDS) in a population of patients with chronic obstructive pulmonary disease (COPD).
Methods:
Forty-nine patients with moderate to severe COPD were examined using the ICD-10 criteria for depression. The mean age of the patients was 71 years and 33 (64%) were women. Forty-six (94%) of the patients were also evaluated using the 17-item HDS including the six-item Hamilton Depression subscale (HDSS). Internal and external validity were measured using factor analysis, Cronbach Coefficient alpha, Loevinger coefficient of homogeneity, correlation analysis and ROC-curves.
Results:
Twenty-three (47%) of the patients were depressed according to the ICD-10 criteria for depression. The HDSS but not the HDS showed a good internal validity. An acceptable external validity was furthermore shown for the HDSS.
Conclusion:
The HDSS can be recommended as a suitable depression rating scale for COPD patients.
