Abstract:Decades of research has assessed the benefits of children's and adolescents' friendships, but friendships among youth often dissolve within a matter of months or years. Studies have investigated predictors and consequences of friendship stability with the expectation that, in order for friendships to have a positive or negative influence on youth, they need to be enduring. However, differing methodology used to assess friendships affects the proportion of stable friendships observed, which may confound conclusions. In this meta-analysis a number of methodological and substantive study comparisons were made to assess their contribution to differences in effect sizes across studies of friendship stability. Evaluation of the impact of methodological moderators can inform whether there are differences in methodology that can significantly bias effect sizes of friendship stability. Results suggest that time lag between measurement occasions and presence or absence of a school-year transition impacts friendship stability. However, despite differences in methodology, most differences investigated did not significantly impact friendship stability. This supports the validity of the conclusions drawn from literature on friendship stability.

儿童和青少年友谊的稳定性：荟萃分析

摘要：数十年来的研究评估了儿童和青少年友谊的益处，但青年之间的友谊通常在几个月或几年内就消失了。研究已经调查了友谊稳定的预测因素和后果，并期望为了使友谊对年轻人产生正面或负面影响，友谊必须持久。但是，用于评估友情的不同方法会影响所观察到的稳定友情的比例，这可能会混淆结论。在这项荟萃分析中，进行了许多方法学和实质性研究比较，以评估它们对友谊稳定性研究中效应大小差异的贡献。对方法主持人的影响进行评估可以告知方法上是否存在差异，这些差异会严重影响友谊稳定性的影响大小。结果表明，在测量时机与是否存在学年过渡之间的时间差会影响友谊的稳定性。但是，尽管在方法上有所不同，但大多数调查的差异并没有显着影响友谊的稳定性。这支持了从友谊稳定性文献中得出的结论的有效性。
