Appropriate K‐corrections for MMPI‐168 factor scales and for a general psychopathology screening scale (PSY) were derived empiricaily. Percentile distributions of the K‐corrected scales in a large normal sample ( N = 1438) were determined, and a percentile profile sheet was constructed to facilitate clinical use ( N = 1048). The validity of the K‐corrected scales in distinguishing psychiatric patients from normals is examined.
