207Frankl is describing, (b) something different from the usual neuroses, and (c) a characteristic of psychopathological as distinguished from "normal" groups.The results of 225 subjects, comprising two nonpatient and three patient samples, consistently support the noogenic hypothesis: (a) The relationship between the scale and a questionnaire designed by Frankl to describe the factors involved in his concepts was high; (b) the relationship of the scale to an established measure of traditionally conceived psychopathology, the M MPI, was low; and (c) the scale significantly distinguished patient from nonpatient populations, showing a predicted progressive drop in scores to match the level of pathology assumed by the nature of the group.Further study of iioogenic neurosis by the Purpose i l l Life Test and other methods is needed in order to answer a number of questions which present data treat only partially, to define the dynamic properties which would make possible diagnostic isolation of this syndrome, and to determine the variables which affect it. The work reported herein is considered primarily heuristic and exploratory rather than definitive. REFERENCES 1. CRONBACH, 1,. J. nnd MEEHL, P. E. Construct validity in psychological teats. Peychol.
