Abnormal Involuntary Movement Scale (AIMS) and Extrapyramidal Symptom Rating Scale (ESRS): Cross-scale comparison in assessing tardive dyskinesia

High concordance between the scales for dyskinesia scores was found. Findings suggest that the ESRS CGI-SD score can serve as a simplified criterion for identifying AIMS-defined TD, and may be a useful tool for future research-based TD analyses, when occurring in the context of a full movement disorder assessment.
