The Social Phobia Inventory (SPIN) is a 17-item self-report scale developed by Connor and Davidson (2000) to screen for and measure the severity of social anxiety. It covers fear, avoidance, and physical symptoms over the past week, rated 0-4. Source: Connor & Davidson, 2000 (PubMed).
How to use it: Rate each statement for the past week as honestly as you can. Higher scores reflect more social anxiety.
Reading your score: In the original validation a total around 19 separated people with social phobia from controls; the bands here are general guides, not a diagnosis.
Limitations: The SPIN is a self-report screening tool, not a diagnosis. A high score suggests a fuller clinical evaluation is worthwhile.
When to seek help: If social anxiety limits your work, school, or relationships, consider a mental health professional or evidence-based therapy. If you ever feel you might harm yourself, contact 988 (US) right away.
