FAQ

How are clinical cutoffs defined on screening tools?
Standardized inventories use validated score thresholds (e.g. PHQ-9: 5=mild, 10=moderate, 15=moderately severe, 20=severe; GAD-7: 5=mild, 10=moderate, 15=severe).
Is my questionnaire response data kept private?
Yes. All scoring calculations execute entirely in your local web browser. No personal health information (PHI) or questionnaire answers are transmitted or stored remotely.
Does a high screening score equal a medical diagnosis?
No. Screening questionnaires indicate symptom severity but do not constitute a formal diagnosis. If you are experiencing distress, please share these results with a licensed psychiatrist or mental health professional.
