Abstract
This study of adolescent friendship investigated the features of adolescent (1) self-expression, (2) expectation of other's expression, and (3) the relationship between self-expression and expectation of other's expression. Junior and senior high school students (N=731) filled out a questionnaire about these aspects of their friendships. Factor analysis of the data revealed 4 factors for self-expression and expectation of friends' expression, respectively, and the following was found in relation to these factors. (1) Boys reported expression of "dissatisfaction and demand for friends' behavior" more frequently than girls, whereas girls reported expression of "personal limitation and pleasure" more frequently than boys. Senior high school students reported expression of "personal limitation and pleasure" and of "opinion", more often than junior high school students. (2) Girls expected others' expression more than boys , for all factors. (3) Expression of "personal limitation and pleasure" and "opinion" correlated modelately with all factors, for expectation of friends' expression, whereas expression of "dissatisfaction and demand for friends' behavior" and "rejection of friends' request" almost did not correlate significantly with expectation factors.
