The Mayo Clinic Automated MMPI Program: Crossvalidation with psychiatric patients in an army hospital

Abstract

The present study has demonstrated that considerations of age and, t o a lesser degree, sex in medical patients with the MMPI 1-3/3-1 profile can improve significantly the association of medical diagnostic classification compared with base rates for organic only of 3995, for functional-psychologic of %yo',, and for mixed of 28%. The relationship of age and medical diagnosis was stronger in males than in females. SUMMARY This study investigated the moderating effects of age and sex on the association of organic, psychologic, and mixed medical diagnoses and the Minnesota Multiphasic Personality Inventory (MMPI) 1-3/3-1 profile. A group of 178 medical patients (86 males and 92 females) was selected as representative of the age distribution of a larger sample of patients with this profile. All profiles matched the Halbower rules. The results were as follows : (1) 39y0 of all patients had only organic diagnoses, whereas 34% had only psychologic diagnoses; ( 2 ) psychologic diagnoses alone were found primarily in the group less than 40 years of age (66%); (3) males and females did not differ significantly with regard t o diagnostic classification, but a trend existed for more psychologic diagnoses among females; (4) median age split yielded significant chi squares for both sexes with regard to organic only vs. some psychologic diagnoses; (5) clinical usefulness was improved with optional age cutoff for each sex.

A Study of Active Duty Military Personnel With the MMPI-2

“…By far the greatest use of the MMPI in the military services has involved its application with a wide variety of clinical problems in military medical centers and correctional facilities (Benton, 1945;Benton & Probst, 1946;Berdie, 1946;Bloom, 1986;Borton & Brill, 1945;Brodsky, Mehaffey, & Rhoads, 1965;Clark, 1984Clark, , 1949Clark, , 1952Clark, , 1953Gough, 1946;Hedlund, Morgan, & Master, 1972;Klonoff, Clark, Horgan, Kramer, & McDougall, 1976;Modlin, 1947;Voors, Rytel, Jenkins, Pierce, & Stewart, 1969;Winstead, Lawason, & Abbott, 1976).…”

Computer utilization and clinical judgment in psychological assessment reports

“…Results from such studies have been mixed, as the small sampling of studies reviewed here suggests. For example, Hedlund, Morgan, and Master (1972), found that there was a false positive rate of 62% when clinicians' ratings based on discharge summaries were compared to narrative statements produced from MMPI reports. This contrasted with data reported by Butcher et al (1998) that examined the utility of computer-based MMPI-2 reports in Australia, France, Norway, and the United States.…”

Relative User Ratings of MMPI-2 Computer-Based Test Interpretations

“…Another early study along these lines was conducted by Hedlund, Morgan, and Master (1972). They investigated the validity of a CBTI developed by the Mayo Clinic for the MMPI.…”
