Both calculators run independently — change the inputs on either side to compare results.
Sleep Quality Index Calculator
Score your sleep quality across five clinically recognized dimensions — duration, latency, efficiency, disturbances, and daytime function. Ideal for anyone investigating whether poor sleep is affecting their health or productivity.
Depression Severity Calculator
Screen for depression symptoms using PHQ-9 criteria by rating five core symptoms. Use this when you want a quick, evidence-based indicator of depression severity to discuss with a healthcare provider.
Depression Score
0 points
A total of 0-4 indicates minimal depressive symptoms on the PHQ scale. No specific treatment is typically indicated at this level.
Scores follow the PHQ-style 0-3 per item across 5 items (0-15 here); the standard PHQ-9 severity cutoffs of 5, 10, 15 and 20 are applied to these items.
