PHQ-9 (Patient Health Questionnaire-9) calculation
The PHQ-9 (Patient Health Questionnaire-9) is a widely used tool for screening, diagnosing, and monitoring depression. It consists of 9 items scored on a scale from 0 (not at all) to 3 (nearly every day), with a total score ranging from 0 to 27; higher scores indicate greater severity of depressive symptoms.

Example 4

Warning Formula : Percentage of measurements over the threshold in the last x days
This example demonstrates how to create a formula that checks whether a specified percentage of a participant's measurement submissions within the last X days exceed a defined threshold. This formula is particularly valuable for alerting doctors when health metrics—such as blood glucose, blood pressure, weight etc.—consistently surpass the normal range over a given period (e.g., two weeks).
