Age and education do not affect the Caudality (Ca) Scale of the Minnesota Multiphasic Personality Inventory (MMPI)

Age and education effects on the Caudality (Ca) Scale of the Minnesota Multiphasic Personality Inventory (MMPI) were investigated. The MMPI was administered to a sample of 33 lateralized (21 = right hemisphere, 12 = left hemisphere) brain damaged subjects. Demographic data were obtained from hospital records and cross-checked with the subjects. The MMPI profiles were computer scored and Ca Scale t scores were computed. Ca Scale score correlations were computed separately for left and right hemisphere groups for both age and education. All correlations failed to meet conventional standards for statistical significance. Clinical implications are discussed.
