Build rapport: Establish trust with the patient to encourage honest and open responses. 3. Use clinical judgment: Combine the HAM-A results with clinical observations and patient history to make informed decisions. 4. Document findings: Record the scores and any relevant observations meticulously to track progress and share with the healthcare team.
