Q methodology was first introduced by William Stephenson in 1953. It is designed to reduce the level of subjectivity in any given situation by converting qualitative descriptions into quantitative data.
The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used personality assessment comprised of 567 true-false items. It was originally designed to facilitate in psychiatric diagnosis. The MMPI-2 Q-Set was designed to reflect the underlying personality traits found in the MMPI-2 (Appendix A). The MidWestem Q-Sort program, found online at http://www.uni.edu/williamsje/research/raters, sorts 100 descriptive statements into a forced quasinormal distribution. The distribution ranges from bin 1 labeled "Most Descriptive" to bin 7 labeled "Least Descriptive". Each bin can only hold a predefined number of items which forces the rater to approximate a normal distribution with his/her final sort of items (Appendix B).
This current study intended to investigate the test-retest and inter-rater reliability of the MMPI-2 Q-set in order to determine the utility of a number of descriptive terms in adequately describing the personality dimensions measured on a the MMPI-2.
