Symptom Checklist-90 (SCL-90)
90-question symptom check covering 9 dimensions — a broad mental health screening tool.
How are you really doing - across all dimensions of mental health? The SCL-90 covers 90 symptoms across 9 domains: somatization, OCD, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. About 15-20 minutes. Broad psychological symptom assessment, not a targeted diagnostic tool.
How are you really doing — across all dimensions?
Sometimes a single-domain test does not cut it. You might be feeling anxious and depressed and having trouble sleeping and feeling on edge around others. That is when a broader screening tool makes more sense.
The Symptom Checklist-90 (SCL-90) covers 90 symptoms across nine dimensions: somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. Each item rates how much you were bothered over the past week on a 0–4 scale.
What the scores mean
The SCL-90 provides three global indices:
- Global Severity Index (GSI) — overall psychological distress
- Positive Symptom Distress Index (PSDI) — average intensity of symptoms
- Positive Symptom Total (PST) — number of symptoms endorsed
About this scale
Leonard Derogatis developed the SCL-90 in 1973, with a revised version (SCL-90-R) published later. It has been widely used in clinical and research settings as a broad screening tool.
- Internal consistency: α = 0.77–0.90 (subscales)
- Test-retest reliability: r = 0.78–0.90
- Completion time: 12–15 minutes
