In undertaking to find a measure to give us a quantitative basis for the prediction of temperamental integration, we computed the difference between normal and each of the other components on the Humm-Wadsworth profile and, also, the sum of these differences. We did this first for a small number of subjects selected on the basis of known facts concerning their mental health; and then for 1,000 random permanent employees.We found that: (1) the integration index distinguished without exception between subjects known to be psychotic and subjects known to be well adjusted; (2) the component control measures significantly differentiated the means of the 2 groups; (3) distributions of the measures for 1,000 "permanent" employees provided data from which norms could be derived.From this we conclude that the measures of self-mastery provided an additional tool [See FIG. 3. in source pdf] for studying the temperaments of individuals and of groups.Abstract Teaser
