Skinner, Reed, and Jackson (1976) have developed a system for characterizing the shape of MMPI profiles by relating them to three superordinate types--Neurotic, Psychotic and Sociopathic. Using a psychiatric sample, a short form was developed to estimate the position of MMPI profiles in this three dimensional system. An elevation scale was also constructed. Cross validated means, standard deviations, reliabilties and validities supported the use of the short form with psychiatric samples. Examples of the use of the short form were also discussed.
