This study aimed to clarify the relationship between group participation of young working people and the total change of personality from the viewpoint of the desirable change of the self-concept. In this study the desirability of the self-concept was measured in terms of the discrepancy between two definitions of the self: the perceived self and the ideal self.
The directional change in the perceived self toward the ideal self and the high correspondence between the perceived and the ideal self, which were undertaken uniformly after the positive participation in group activities of young people, were considered as the characteristics of the desirable self-concept. We defined this directional change as personality growth.
It was found that the more an individual tended to participate in voluntary groups (circles), the greater was the personality growth, when the group itself indicated the social atmosphere of acceptance and was recognized to be the normative reference grotip by the individuals.
