PRELIMINARY TEST OF INTELLIGENCE : A Brief Test of Adult Intelligence Designed for Psychiatric Examiners

Publication: American Journal of Psychiatry

Abstract

A brief test of adult intelligence designed for psychiatric examiners is reported. The test (Preliminary Test of Intelligence) consists of vocabulary, comprehension, similarities and differences, and arithmetic items and can be administered and scored in 5 to 15 minutes. Preliminary standardization data on 150 subjects ranging in age from 11 to 70 years show satisfactorily high correlations with the Wechsler-Bellevue Intelligence Scale. The test, together with complete instructions for administration, scoring and interpretation is included in the text. Tentative norms permit the classification of intelligence level in one of four categories: above average, average, below average and markedly below average. The I. Q. range within each category for the standardization group is reported.
