Reliability (Internal Consistency) of the Wechsler Memory Scale and Correlation with the Wechsler-Bellevue Intelligence Scale.

Abstract

Although the Wechsler Memory Scale (WMS) was published in 1945, no information is available concerning either its reliability or its validity. The lack of these vital data, however, has not precluded extravagant statements about the diagnostic efficacy of the scale. For example, Kogan in a review of the test states: "Thus, [by means of WMS] it is possible to distinguish accurately between the kind of memory impairment which is merely one aspect of generalized mental inefficiency and that which represents a specific decrement in memory function." In the same review Kogan also indicates that differences among WMS subtest scores will be useful in differential diagnosis. The study reported here is an investigation of two aspects of WMS: its reliability and its correlation with the Wechsler-Bellevue Intelligence Scale (W-B).
