New York State Psychiatric Institute and Hospital Since Woodworth's questionnaire was devised and published, many revisions have appeared adding improvements to his original inventory but usually retaining its general form and some of its items. In the attempt to validate these tests, research workers have made use of the entire gamut of social deviants, from the problem child through the delinquent and criminal to psychoneurotic and psychotic individuals. In the present study a psychopathological group and a non-psychopathological group were used as criterion groups in the validation of the questionnaire items. Three recent personality tests of the Woodworth Psychoneurotic Inventory pattern were used.
