Assessing depression in a geriatric cancer population

Area of Science:

• Geriatric Oncology
• Psychiatry
• Clinical Psychology

Background:

• Depression is a common comorbidity in geriatric cancer patients.
• Accurate assessment of depression is crucial for effective treatment and improved outcomes in this population.

Purpose of the Study:

• To evaluate the performance of three widely used self-report depression measures in older adults with cancer.
• To determine the clinical utility of the Geriatric Depression Scale-Short Form, Hospital Anxiety and Depression Scale, and Center for Epidemiological Studies Depression Scale-Revised in this specific demographic.

Main Methods:

• A cohort of 201 cancer patients aged 70 years and older undergoing active treatment completed the three self-report scales.
• The Structured Clinical Interview for DSM disorders (SCID) depression module served as the gold standard for diagnosis.
• Analyses included internal consistency, Receiver Operating Characteristic (ROC) curves, sensitivity, and specificity for Major Depressive Disorder (MDD) and minor depression.

Main Results:

• All three scales demonstrated adequate internal consistency and predicted depression above chance.
• Published cutoff scores for MDD showed poor sensitivity, potentially missing 33%-83% of depressed geriatric cancer patients.
• Revised, lower cutoff scores were identified as potentially more effective for this population.

Conclusions:

• While exhibiting good internal consistency, the standard cutoff scores of these popular depression measures are inadequate for reliably identifying depression in geriatric cancer patients.
• The Center for Epidemiological Studies Depression Scale (CES-D) showed the most promise among the three measures.
• Clinicians and researchers should exercise caution and consider utilizing the revised, lower cutoff scores when assessing depression in this vulnerable group.
