The Use of Clinical Impression in Diagnosis. Technical Report 79-07.
Grosek, Robert J.
Three psychologists participated in an examination of the consistency and accuracy of subjective diagnoses of 20 institutionalized mentally retarded young adults and adults. The psychologists' informal ratings of the Ss' degree of retardation (mild, moderate, severe, profound) were correlated with one another and with the retardation levels as determined by the administration of the Broome Functional Behavior Checklist by direct care staff on the wards. Results indicated that the ratings of the psychologists were smilar to one another (average correlation .84), but their ratings were much less in agreement with the checklist than with themselves. The psychologists tended to see the populaton as equally represented by each category of retardation, perhaps matching some internal expectation. Findings suggested that the psychologists were able to use subjective criteria to differentiate among gross differences in retarded individuals, but were unable to diagnose retarded individuals as accurately as the objective checklist.
