Research with the Wechsler-Bellevue test: 1945-1950.

Abstract
Recent (1945-1950) research with the Wechsler-Bellevue test is reviewed. The validity and reliability of the test as a measure of intelligence are no longer questioned. Various short forms of the W-B show high correlations with the full scale but there is no substitute for the full scale in a complete case study. Several modifications in W-B procedure merit immediate adoption. Many of the demonstrated gains in W-B IQ incident to therapy may be due to practice effects. Results regarding correspondence between increase in IQ level and improved psychiatric conditions are equivocal. "Score patterns successfully differentiate groups, but are of comparatively uncertain value in the diagnosis of individuals." One hundred forty-five studies are reviewed.
