An evaluation of two self-report screening measures for mood in an out-patient chronic heart failure population.

OBJECTIVE

To examine the criterion validity of the Hospital Anxiety and Depression Scale (HADS) and the Geriatric Depression Scale 15-item (GDS-15) in a community sample of Chronic Heart Failure (CHF) out-patients.

METHODS

Eighty-eight of 203 older adults with confirmed CHF responded to a postal survey and participated in a face-to-face interview. The GDS-15 and HADS were compared to diagnoses from the Structured Clinical Interview for DSM-IV (SCID-I), using a receiver operating characteristic (ROC) analysis and positive and negative predictive values, sensitivity and specificity for various cut-off points.

RESULTS

For all depressive disorders, the area under the ROC curve for the GDS-15 was 0.883 and a cut-off of 5 gave a sensitivity of 0.818 and a specificity of 0.833. The area under the ROC curve for the HADS Depression (D) and Anxiety (A) were 0.889 and 0.941 respectively. At a cut-off of 7, the HADS-A gave a sensitivity of 0.938 and a specificity of 0.847. At a cut-off of 4, the HADS-D gave a sensitivity of 0.864 and a specificity of 0.788.

CONCLUSIONS

The GDS-15 and HADS are valid screening tools for detecting depression in aged CHF out-patients. However, use of the HADS requires reduced cut-points to ensure that patients with mood disorder are not missed in this population.
