Screening depression in primary care: back to the basics with a new tool

Area of Science:

• Family Medicine
• Psychiatry
• Clinical Psychology

Background:

• Depression screening is crucial in primary care settings.
• The Self-Rating Depression Scale (SDS) is commonly used, while the Depression Adjective Checklist (DACL) is less established in family medicine.
• Patient self-reported symptoms often go undiagnosed by treating physicians.

Purpose of the Study:

• To evaluate the prevalence of depression among family practice patients using two different screening inventories.
• To assess the accuracy of resident physicians in diagnosing depression in these patients.
• To identify discrepancies between patient-reported depression and physician diagnosis.

Main Methods:

• 377 family practice patients were screened using the Self-Rating Depression Scale (SDS) and the Depression Adjective Checklist (DACL).
• Patient depression scores were compared against diagnoses made by resident physicians.
• Prevalence rates for mild and severe depression were calculated for both inventories.

Main Results:

• 41% of patients reported mild to severe depression on the SDS; 37% on the DACL.
• A significant number of patients scoring in the mild (85%) and severe (70%) depression ranges were not diagnosed by residents.
• The DACL identified a higher percentage of patients in the severe depression range (15%) compared to the SDS (4%).

Conclusions:

• There is a substantial underdiagnosis of depression in family practice, despite the use of validated screening tools.
• Family physicians may benefit from enhanced training in depression recognition and diagnosis.
• Further research is needed to understand the barriers to accurate depression diagnosis in primary care.
