Development and preliminary validation of the Concise Neuropsychological Screening Inventory (CNSI): A clinical tool for use in psychiatric settings

We describe the development and preliminary validation of the Concise Neuropsychological Screening Inventory (CNSI), designed to afford clinical psychologists working in psychiatric settings a simple, rapid, and objective assessment of 10 vital left- and right-hemisphere brain functions: (1) Receptive and Expressive Language, (2) Orientation, (3) Attention/Concentration/Immediate Memory, (4) Recent Auditory and Visual Memory, (5) Remote Memory, (6) Motor/Sensory/Tactile Functioning, (7) Visual/Spatial/Motor Integration, (8) Academic Functioning, (9) Intellectual Processes, and (10) Judgment and Reasoning. Preliminary findings suggest that the CNSI can discriminate patients diagnosed with organic mental syndrome from patients with various psychiatric disorders, including chronic schizophrenia (i.e., specificity in screening). Moreover, with regard to predicting neuropsychological differences among various diagnostic groups, the CNSI is superior to some of the most commonly employed tests by psychologists in psychiatric settings (e.g., WAIS-R Digit Span, Digit Symbol, and Bender-Gestalt).
