Despite the documented importance of friendship for the well-being of young adults, there is a paucity of work mapping factors associated with friendship dissolution and maintenance during this developmental period. We examined whether implicit theories of friendships – specifically, growth beliefs (i.e., the belief that friendships can be developed) and destiny beliefs (i.e., the belief that friendships are either meant to work or not) — were associated with endorsement of dissolution and maintenance responses in two types of challenging situations occurring with same-gender friends. One hundred forty-five undergraduate students (80 females, M_age = 20.71, SD = 1.46) completed an online questionnaire. Participants read twelve hypothetical situations depicting transgressions by a friend (i.e., violations of friendship expectancies) or conflicts of interest (i.e., differences of needs, desires, or opinions) and reported how likely they would be to engage in strategies reflecting maintaining the friendship or dissolving it, either by ending it completely or diminishing its quality. They also completed a scale assessing implicit theories of friendships. Participants endorsed dissolving the friendship more strongly when the friend had transgressed than in conflicts of interest, whereas maintenance strategies were endorsed more strongly in conflicts than in transgressions. Moreover, higher destiny beliefs were associated with greater endorsement of ending the friendship and weaker endorsement of maintaining it; in contrast, higher growth beliefs were associated with greater endorsement of maintenance. Findings provide new insight into when and why young adults may dissolve or maintain a friendship.

风雨同舟？：年轻人对友谊的隐含信念以及他们报告的与同性别朋友的解散和维持策略的使用

尽管有文献记载友谊对年轻人福祉的重要性，但在这一发展时期，缺乏与友谊解体和维持相关的工作映射因素。我们研究了关于友谊的隐含理论——特别是成长信念（即友谊可以发展的信念）和命运信念（即友谊要么是为了工作，要么不是）——是否与对解散和维持的认可有关在与同性朋友发生的两种具有挑战性的情况下的反应。145名本科生（80名女性，M_年龄=20.71，SD= 1.46) 完成了在线问卷调查。参与者阅读了 12 种假设情况，描述了朋友的违规行为（即违反友谊期望）或利益冲突（即需求、愿望或意见的差异），并报告了他们参与反映维持友谊或保持友谊的策略的可能性有多大。通过完全结束它或降低它的质量来溶解它。他们还完成了评估内隐友谊理论的量表。与利益冲突相比，参与者更强烈地支持在朋友违反时解除友谊，而在冲突中比在违反时更强烈地支持维持策略。而且，更高的命运信念与结束友谊的更大支持和维持友谊的更弱支持有关；相比之下，更高的成长信念与更大的维护支持有关。调查结果为年轻人何时以及为何会解散或维持友谊提供了新的见解。
