The Neurological Evaluation Scale (NES): a structured instrument for the assessment of neurological signs in schizophrenia

Psychiatry Res. 1989 Mar;27(3):335-50. doi: 10.1016/0165-1781(89)90148-0.


The significance of neurological signs in schizophrenia is poorly understood. In part, this may reflect the marked variability in the methods of ascertainment in previous studies. The Neurological Evaluation Scale (NES) is designed to standardize the assessment of neurological impairment in schizophrenia. The battery consists of 26 items. Data on the interrater reliability for total score, functional areas of interest, and individual items are presented. Preliminary validity data demonstrate the ability of the battery to discriminate patients with schizophrenia from nonpsychiatric controls.
