恋愛関係の排他性に及ぼす青年期の愛着スタイルの影響について Exclusivity in romantic relationships as a function of early adult attachment styles
This study was conducted in order to examine effects of early adult attachment styles on exclusivity of romantic relationships. Two hundred fifty seven undergraduates participated in Study 1, which examined how early adult attachment styles influence one's "sense of exclusivity" and "expressions of the sense of exclusivity," from the perspective of attachment dimensions. Results showed that, the higher the level of anxiety was, the more regularly a "sense of exclusivity" was experienced. Furthermore, the higher the level of avoidance was, the lower the "sense of exclusivity" was experienced. In addition, participants with high avoidance were less likely to express their "sense of exclusivity." In Study 2, participants were limited to 104 undergraduates who were currently involved in romantic relationships. Exclusivity of romantic relationships as a function of early adult attachment styles was examined with the construction of causal models as follows: first, two dimensions of early adult attachment, second, feelings of discomfort when a third person intervenes in the romantic relationships, and, lastly, coping behaviors for feelings of discomfort. Results revealed that anxiety increased the frequency of lingering/sadness, while avoidance reduced the frequency of these feelings. Moreover, results indicated that avoidance caused a higher tendency to resort to destructive coping behaviors and a lower tendency towards selecting constructive coping behaviors, such as "voice." These results are discussed in terms of the relations between early attachment styles, emotional experiences, and destructive behaviors in romantic relationships.
