This assessment should be used as screening + severity quantification. It translates hard-to-describe emotional and somatic experiences into structured signals you can communicate and track.

What this assessment does

The tool samples symptom frequency over a recent time window (often two weeks), usually aligned with validated frameworks such as PHQ-9 and GAD-7.

Model logic: from input to output

Input captures symptom clusters such as mood, anhedonia, sleep, energy, concentration, tension, and worry. Output maps to severity bands and helps decide action level: observe, intervene, or seek urgent professional care.

Practical use in care pathways

Use scores to improve communication with clinicians and to monitor trend over time. Repeated measurement is especially useful when you are in treatment and need to evaluate whether recovery is stable or fluctuating with stress events.

Critical boundary

Screening is not diagnosis. If you have suicidal ideation, self-harm risk, or immediate safety concerns, contact local emergency services or crisis support immediately.

Ethical use

Do not use mental-health screening scores for hiring, elimination, or punitive evaluation in organizations.
