Social desirability and responses to items from three MMPI scales: D, Sc, and K

Abstract

For random samples of 25 D and 32 Sc items, and for 29 of the 30 K items, ratings of social desirability were correlated with the probabilities that the items would be endorsed when the MMPI was used as a personality test (based on proportion of a college student sample actually endorsing each item). The correlations were .82 and .89 for the D and Sc items respectively. For the K-scale items, correlations of social desirability were computed with endorsement probabilities from a "typical college sample" (r = .50), and "Average-K" group (r = .38), and a "high-K" group (r = .66). "The results were interpreted as demonstrating the validity of K as a measure of the set to respond to items in terms of their social desirability."
