This manual presents information on the Minnesota Multiphasic Personality Inventory (MMPI), primarily directed to counselors and clinicians who work with university counseling center clients, private practice clients, and mental health clinic clients who are not usually psychotic or neurotic but are having difficulties in one or two areas. This format is used in presenting the chapters on the Validity, Clinical, and Research Scales: an introduction and general information about the scale is presented, then high score interpretations are given, usually divided into moderate elevations (60 through 70 T-score points) and marked elevations (70 T-score points or above). These interpretations are followed by the low score interpretations (usually 45 T-score points or below). Combinations of scales are then noted and the interpretations for them are given. All Clinical and Validity scales in the combinations are at a T-score of 70 or above, unless otherwise noted and are listed in order from the highest to the lowest peaks. Research scale combinations use scales at a T-score of 60 or above. Chapters are also included on interpreting the MMPI and the effects of race and culture on MMPI profiles. Separate discussions by each of the two authors provide sample MMPI interpretations with sample profiles. Appendices include the New Scale Item Composition Group Booklet Form; the New Scale Item Composition R Form; and the Validity, Clinical, and Research Scales Intercorrelations for Two Normal Populations.
