Many procedures with variable validity and reliability have been developed in research settings to evaluate adventitious movements and related phenomena in specific populations, e.g., people with schizophrenia treated with dopamine antagonists, but these only provide global assessments or rate specific movements. A battery for rating individuals with possible movement disorders in a comprehensive way in clinical settings is needed so a protocol to assess briefly and thoroughly potential movement disorders was videotaped for five prepubertal boys with autistic disorder and severe mental retardation in a clinical trial. Utilizing a Movement Assessment Battery, four raters independently scored videotapes of 10-16 movement assessments of each of the five subjects. Experienced raters attained agreement of 59% to 100% on ratings of tardive dyskinesia and 48% to 100% on tics. Hindrances to reliability included poor quality of some tapes, high activity of subjects, and fatigue of raters.
