人間関係の選択性と態度の同類性: ダイアド・データを用いた検討

Abstract

The present study examined attitude similarity among the Japanese using data from a national representative dyadic survey. The Euclidean distance of responses to eight 4-point survey items measuring the values of the respondents and alters was used as the index of the attitude similarity of dyads. Relationships between attitude similarity and urbanism and the size of one's personal network were measured as indexes of relational selectability. Multilevel analyses revealed the following results: (1) attitude similarity was significantly high among the Japanese; (2) the size of one's personal network positively and significantly correlated with attitude similarity; and (3) the correlation remained significant even when the similarity of demographic profiles was controlled. These results imply that attitude similarity is determined not by relational structure at the societal level but rather relational structure at the personal network level. The implications of the findings that attitude similarity was relatively weak and did not correlate with urbanism in regard to the subcultural theory of urbanism (Fischer, 1982) are discussed.
