If you want to turn reading into self-measurement, continue into an assessment.
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.
