A. DEFINING AND MEASURING MORALET h e definitions of morale suggested by those who have studied the problem in relation to the adjustment of individuals in different social circumstances and conditions of group activity have been reviewed in other studies (4,7,10,14,15). Only those concepts of morale which seem applicable to an interpretation of this study will be referred to here. G. W. Allport thinks that morale has to do with individual attitude in group endeavor and that it is characterized by three essential features, two of which are personal and private and the third is largely social. An individual, according to his view, to have good morale, must have convictions and values; he must be aware of tasks to do in order to defend and extend his values and there must be essential harmony between his values and aims and those of his group.

For practical purposes of morale building and morale measurement, they advance *Received in the Editorial Office on November 8, 1943, and published immediately at Provincetown, Massachusetts. JOURNAL OF PSYCHOLOGY the hypothesis that, in addition to personal factors of physical and mental well-being and a feeling of security in one's economic and family relationships and in one's religious values, there are attitudes toward the war effort and participation in it with the Allied Nations which are factors in morale.T h e attitudes assumed to be determinants of morale are: ( a ) an acceptance of the significance of the war goals of our nation; ( b ) a belief in the significance of one's participation in the war effort; ( c ) confidence in the accuracy of the source of one's information, both historical and present, about the war, the difficulties to be encountered and the progress being made in fighting the w a r ; ( d ) confidence in the leaders of the war effort; ( e ) an acceptance of our common cause with the...
