We analyzed the results of questionnaire surveys answered by a total of 556 junior high school, high school and university students (275 males and 281 females). A total of 499 individuals (89.7%; 241 males, 258 females) belonged to a group of friends, and the mean size of these groups was 5.82 individuals (SD=3.69) overall, 6.27 (SD=4.19) for males, and 5.41 (SD=3.12) for females. As a result of factor analysis, there were three reasons for belonging to a friend group: “Avoidance of isolation”, “emotional support” and “information sharing”. “Avoidance of isolation” and “information sharing ” were higher among high school students and university students than junior high school students, while “emotional support” was higher among female students than male students. It was confirmed that there are two reasons for belonging to a group of friends in adolescence: a passive reason, avoiding isolation, and a more active reason, sharing information with and supporting each other.}, pages = {1--10}, title = {青年期における友人グループに所属する理由 ――学校段階,性別による検討――}, year = {2020}, yomi = {スギタ, アヤカ and マツナガ, シノブ and コウノ, ヨシアキ} }
