MMPI profiles from a random sample of 1,064 physical (nonpsychiatric) disability insurance claimants were compared with those of 14,306 general medical patients, matched for age and sex, seen at the Mayo Clinic. In contrast with the latter, the disability insurance claimants produced mean profiles in the clinically significant range. These results confirm earlier clinical findings that between 35 and 44 percent of the physical disability sample suffered from moderate to severe psychoneuroses or personality disorders.Abstract Teaser
