Validity and reliability of the Neuropsychological Impairment Scale (NIS).
The Neuropsychological Impairment Scale (NIS) is a self-report screening instrument intended to identify neuropsychological symptoms and deficit. A validity study that used 40 neuropsychiatric patients compared four NIS derived measures with the four best Halstead-Reitan general indicators of impairment. Additionally, two test-retest reliability studies with both patient and normal samples are reported. Results support and corroborate previous validity findings and suggest that the NIS is an acceptably stable and reliable measure.
