The MMPI: A Contemporary Normative Study.
Colligan, Robert C.; And Others
The original normative base for the Minnesota Multiphasic Personality Inventory (MMPI) was established in the late 1930's and early 1940's. While there was a refining of this original sample in 1957, no contemporary standards for normal people have been published. To develop new norms a random sample of 1,919 households in and near Rochester, Minnesota, was contacted. Telephone interviewers obtained demographic information and determined whether there were physically or mentally handicapping conditions among potential subjects. MMPI's were returned from 667 males and 800 females (an 86 percent response rate). This contemporary sample was somewhat older (mean age = 45, F; 43, M) and better educated (mean = 13 years, M, F) than the original sample. Responses from this sample yielded MMPI profiles significantly elevated in comparison with the original norms, with men showing greater increases than women. Many scales also demonstrated age-related changes. The results are of practical as well as statistical significance. They suggest that clinicians take a somewhat more conservative approach to profile interpretation and also integrate the impact of age and sex on profile configuration. (Author/PN)
