SOCIAL DESIRABILITY AND THE TSC MMPI SCALES

Abstract
The seven Minnesota Multiphasic Personality Inventory (MMPI) scales developed by Tryon, Stein, and Chu were intercorrelated and factor analyzed by the method of principal components. Included in the analysis were three marker scales for the first three principal components of the MMPI: the SD scale, the R scale, and the L scale, respectively. All of the TSC scales had loadings of .61 OT higher on the first principal component marked by the SD scale with a loading of -.90. The results show that there is con- siderable redundancy in the seven TSC scales and that each of lthe scales has its largest loading on the first principal component.
