ADAM - Apathy, Depression, Anhedonia Measure

Welcome

The Apathy-Depression-Anhedonia Measure (ADAM) is a brief, 10-item questionnaire designed to dissociate symptoms of apathy, depression, and anhedonia using a data-driven, weighted scoring system.

After completing the questionnaire, your responses will be automatically scored to generate a phenotypic profile across eight subscales. You will be able to download your results as a CSV file.

Important: This tool is designed for research and educational purposes only. It is not a clinical diagnostic instrument and should not be used as a substitute for professional mental health assessment. If you are experiencing distress, please contact a healthcare professional or a crisis helpline in your area.
