Personality, Self-Disclosure and Friendship Between Chinese University Roommates

The present study examined the relations among personality perceptions, self-disclosing behavior, and friendship strength between Chinese roommates. These variables are rarely measured together and, when jointly assessed, allow for the disentanglment of personality factors from the social behavior of self-disclosure, making it possible to assess the role of self-disclosure behavior in the nexus of personality perceptions relating to friendship. One hundred and thirty-one university students rated their own and their roommate's personality, their self-disclosing behavior, and the strength of their friendship six months after being assigned to room together. It was found that self-ratings on the personality dimension of application were related both to one's friendship ratings and one's self-disclosing behavior, suggesting that personality variation is responsible for some of the well-established (Collins and Miller, 1994) links between self-disclosure and friendship strength. After controlling for self-rated application, it was found that both the respondent's and the roommate's self-disclosing behavior contributed separately to increasing the respondent's friendship ratings, as has also been found in Western research. Surprisingly, respondent self-disclosure was unrelated to how respondents perceived their roommates. However, the perceived roommate qualities of helpfulness and intellect were associated with the respondent's friendship ratings, suggesting that other, unmeasured social behaviors are being exchanged between roommates to enhance their friendship. Future research should examine these other behavioral mediators of friendship, so that we can develop a behavioral topology for this important social relationship and link these behaviors to dimensions of interpersonal perception.
