Members of a MEDEX training staff (N = 13) estimated the similarity of 16 medical occupations-professions (including the MEDEX concept). Evaluative dimensions utilized by these judges to form their judgments of scale similarity were extracted using a recently proposed multidimensional scaling method-model. Five judgmental factor-dimensions were identified (tentative labels: I. Amount of training—degree of responsibility—prestige; II. Therapist; III. Nurse; IV. Technician; and V. Hospital nursing staff authority) which accounted for up to 86% of the variance of the averaged similarity estimates. These factor-dimensions as well as the methodology employed were discussed. Future research was suggested.
