An attitude survey, a peer nomination form, and self-ratings, of "interest in and enthusiasm for naval aviation," were administered to 8 sections of naval aviation cadets (N = 210). The 3 morale measures intercorrelated about .4. Against a pass-withdraw criterion, the 3 validity coefficients (biserial r''s) were .90 for the group estimate of each cadet''s morale (based on peer nomination), .83 for the self-estimate, and .30 for the survey estimate. "The conclusion is offered that peer nominations and direct self descriptions may have greater utility in reflecting involvement in a training program than does the traditional "morale index" derived from a survey instrument.".
