Comparison of wechsler vs. mayo summary scores in a clinical sample

Normative bases for the Wechsler Adult Intelligence Scale‐Revised (WAIS‐R) and the Wechsler Memory Scale‐Revised (WMS‐R) recently were extended through age 97 with the publication of norms that permit computation of MAYO IQs for the WAIS‐R and MAYO Memory Indices for the WMS‐R. This study compares traditional Wechsler summary scores with their corresponding MAYO values in a clinical sample. MAYO summary scores are correlated highly with traditional Wechsler values, and concordance rates are also strong. Despite their similarities MAYO summary scores and traditional Wechsler values are not interchangeable. Cautions are discussed relative to the use of both MAYO and traditional Wechsler IQs and Memory Indices.
