Depression in general practice attenders.

Area of Science:

• Psychiatry and Mental Health
• General Practice and Primary Care
• Epidemiology of Mental Disorders

Background:

• Depressive symptoms are common in primary care settings.
• Understanding the prevalence and characteristics of depression in general practice is crucial for effective management.
• The Zung Self-Rating Depression Scale (ZSDS) is a widely used tool for assessing depressive symptoms.

Purpose of the Study:

• To assess the prevalence of depressive symptoms in patients attending general practitioners using the Zung Self-Rating Depression Scale.
• To explore sociodemographic influences on depressive symptom reporting.
• To compare the symptom profiles of general practice patients with depression to those referred for psychiatric assessment.

Main Methods:

• A cross-sectional study involving 251 patients routinely attending general practitioners.
• The Zung Self-Rating Depression Scale (ZSDS) was administered to all participants.
• Statistical analysis was used to identify predictors of higher Zung scores and compare patient groups.

Main Results:

• A total of 21% of the general practice sample (53 subjects) scored above the threshold for significant depression (Zung score ≥ 40).
• Prevalence was 24% for females and 15% for males, consistent with other Sydney-based studies.
• While total Zung scores were similar between general practice patients and psychiatric referrals, the former reported less severe mood disturbance, irritability, crying, and weight loss.

Conclusions:

• Depressive symptoms are prevalent in general practice, with a significant proportion of patients meeting criteria for depression.
• Sociodemographic factors like lower social class and female sex showed weak associations with higher depression scores.
• Observed differences in symptom severity suggest potential variations in clinical presentation between primary care and psychiatric populations, or demographic disparities between samples.
