Construct validity of the MMPI-2 College Maladjustment (Mt) Scale.

The construct validity of the MMPI-2 (Minnesota Multiphasic Personality Inventory-2) College Maladjustment (Mt) Scale was examined using 376 student clients at a university psychological clinic. A principal components analysis and correlations of Mt scale scores with clients' and therapists' ratings of symptoms and functioning showed that the Mt scale identifies the presence of maladjustment as defined in terms of depressive and anxious symptoms. There is no evidence to show that the scale is specific to college students or that it is sensitive to severe psychological disturbance. The Mt scale does not inform the clinician as to why a person is distressed. In addition, there is no evidence from this study to suggest the superiority of the Mt scale over other MMPI-2 maladjustment measures. Therapists should use the entire MMPI-2 profile, not just the Mt scale, to gain the most comprehensive and specific understanding of clients.
