Administered the MMPI, Marlowe-Crowne Social Desirability scale, TAT, and the Rorschach to 19 undergraduates and 19 psychiatric patients. Scores were viewed in terms of a multitrait-multimethod matrix, which was analyzed by a principal-components analysis. 2 traits, adjustment and social desirability, were clearly revealed, although inspection of the matrix appeared to provide only weak evidence for convergent and discriminant validity. Results indicate the usefulness of considering the 2 constructs independent. (15 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
