What are Psychiatry Calculators?
Psychiatry calculators are specialized clinical tools that assist psychiatrists and mental health professionals in psychiatric symptom assessment, diagnostic scale application, and psychotropic medication dose adjustment. They enable application of scales such as Hamilton for depression, calculation of benzodiazepine equivalencies, assessment of mental disorder severity, and guidance of psychopharmacological therapeutic decisions. Based on psychiatry society guidelines, mental health protocols, and evidence in psychopharmacology, these calculators standardize assessments, facilitate clinical evolution monitoring, and assist in individualization of psychiatric treatments based on objective data.
When to Use These Tools
- Assessment of depressive symptom severity with Hamilton Scale
- Calculation of equivalencies between different benzodiazepines
- Monitoring response to antidepressant treatment
- Suicide risk stratification in psychiatric patients
- Evidence-based psychotropic medication dose adjustment
- Standardization of assessments in mental health services

Frequently Asked Questions
How to interpret the Hamilton Scale?
The Hamilton Depression Rating Scale (HAM-D) ranges from 0-52 points (17-item version). Score 0-7: normal, 8-13: mild depression, 14-18: moderate, 19-22: severe, ≥23: very severe. It is used for diagnosis, severity assessment, and monitoring response to antidepressant treatment.
How to calculate benzodiazepine equivalency?
Diazepam 10mg is used as reference. For example: alprazolam 0.5mg = diazepam 10mg, clonazepam 0.5mg = diazepam 10mg, lorazepam 1mg = diazepam 10mg. To switch, calculate total daily equivalent dose and divide according to new drug. Reduce 10-25% of dose when switching to avoid toxicity.
Do scales replace clinical assessment?
No. Psychiatric scales are complementary tools that standardize and quantify symptoms, but never replace detailed clinical interview, mental status examination, and professional judgment. They should be interpreted in the complete clinical context of the patient.
