At 3-week intervals during their first term at the university, 84 male and female freshman completed questionnaires regarding their relationships with two same-sex individuals whom they had just met. Results showed that dyads which successfully developed into close friendships by the end of the fall school term differed behaviorally and attitudinally from dyads that did not progress. As the friendships developed, the intimacy level of dyadic interaction accounted for an increasing percentage of the variance in ratings of friendship intensity beyond that accounted for by the sheer quantity of interaction. Ratings of relationship benefits were consistently positively correlated with friendship intensity and increased as the relationship progressed. There were no differences in ratings of relationship costs between close and nonclose friends. Dyadic behavior patterns and attitude ratings at the end of the fall school term were good predictors of friendship status 3 months later. Motivational and situational factors were also correlated with friendship outcomes.
在大学第一学期，每隔3周，84名男女新生就他们与刚结识的两名同性个体的关系填写问卷。结果显示，到秋季学期末成功发展为亲密友谊的二人组在行为和态度上与未取得进展的二人组有所不同。随着友谊的发展，二元互动的亲密程度在友谊强度评分的方差中所占比例越来越大，超过了单纯互动量所占的比例。关系益处的评分与友谊强度始终呈正相关，并随着关系的发展而增加。亲密朋友和非亲密朋友在关系成本评分上没有差异。秋季学期末的二元行为模式和态度评分是3个月后友谊状态的良好预测指标。动机和情境因素也与友谊结果相关。
