Anxiety and Depression Self-Assessment: SAS and SDS Guide
That heavy feeling that won’t go away. The constant worry that something bad is about to happen. Most people who experience these symptoms never get them checked — not because help isn’t available, but because they don’t realize it’s more than ordinary stress.
The SAS and SDS can help you figure out where you stand. They're screening tools that have been used in clinical settings for over 50 years. They won’t give you a diagnosis (only a professional can do that), but they’ll tell you whether it’s worth taking the next step.
What Is the SAS (Self-Rating Anxiety Scale)?
The SAS asks 20 questions about how you've been feeling over the past week. Psychiatrist William Zung developed it in 1971 for clinical screening.
Scoring: Each item rated 1-4 (none/some/good part/most of the time); 5 items reverse-scored. Standard score = raw score x 1.25.
Interpretation:
* Below 50: Normal range * 50-59: Mild anxiety * 60-69: Moderate anxiety * 70 and above: Severe anxiety
What Is the SDS (Self-Rating Depression Scale)?
The SDS covers the same ground for depression with 20 questions that address emotional, physical, and mental symptoms. Zung developed it in 1965.
Scoring: Each item rated 1-4; 10 items reverse-scored. Standard score = raw score x 1.25.
Interpretation:
* Below 50: Normal range * 50-59: Mild depression * 60-69: Moderate depression * 70 and above: Severe depression
A Note on What These Scores Mean
SAS and SDS are screening tools, not diagnostic instruments. If your scores indicate moderate-severe symptoms, or if these symptoms affect your daily life, please consult a mental health professional.
Consider seeking help if:
* Symptoms persist for more than 2 weeks * They significantly impact work, school, or relationships * You experience suicidal thoughts or self-harm * You’re relying on alcohol or drugs to cope
If you’re in crisis, contact your local crisis hotline.
