Clinical Rating Scales in Psychiatry

1. Overview & Epidemiology

Clinical rating scales are standardized instruments that quantify psychiatric phenomena (symptom severity, cognition, intelligence, personality) so they can be measured, tracked and compared. They turn the qualitative findings of the Mental State Examination into reproducible numbers.

Two fundamental axes the examiner will test (this whole topic hinges on them):

• Who fills it in?

  • Clinician-rated (observer-rated): scored by the examiner from interview/observation — HAM-D, MADRS, HAM-A, YMRS, Y-BOCS, PANSS, BPRS, MMSE, MoCA, ADAS-Cog, Clock Drawing Test. Less prone to lack of insight; needs a trained rater.
  • Self-report (self-rating): the patient completes it — BDI (Beck), PHQ-9, GAD-7, BAI, MDQ, MMPI. Quick and cheap, but vulnerable to insight, bias and symptom exaggeration/minimisation.

• What is the scale FOR? A recurring exam trap: severity scales are NOT diagnostic instruments.

  • Symptom-severity / follow-up scales (most psychiatric rating scales): measure how bad and track change over time — do not make the diagnosis (HAM-D, MADRS, YMRS, HAM-A, Y-BOCS, PANSS, BPRS).
  • Diagnostic instruments: structured/semi-structured interviews tied to ICD/DSM criteria — SCID, MINI, CIDI — these establish a diagnosis.
  • Cognitive screens: MMSE, MoCA, Clock Drawing Test, ADAS-Cog — flag and grade cognitive deficit; screening, not diagnosis.
  • Intelligence tests: WAIS / MAWI, Raven matrices — quantify intellectual performance (IQ).
  • Personality tests: MMPI (objective inventory) vs projective tests (Rorschach, TAT, Szondi).

Context (Hungary / Europe): Debrecen practice uses ICD-11/ICD-10 alongside DSM-5-TR. The German-language Wechsler adaptation MAWI (Hamburg-Wechsler-Intelligenztest) is the historically familiar version in Central-European teaching. The Szondi test (Léopold Szondi, Hungarian psychiatrist) is a classic projective personality test still named in the Hungarian exam bank.
