With a growing body of relationship research relying on dyadic data (i.e., in which both members of a couple are participants), researchers have raised questions about whether such samples are representative of the population or unique in important ways. In this research, we used two large data sets (Study 1: = 5,118; Study 2: = 5,194) that included participants with and without a romantic partner participating to examine if co-participation status has substantive relationship implications. Results showed that co-participation status predicted breakup even after controlling for other known predictors such as satisfaction, although the effect weakened over time (Study 2). There was also tentative evidence that factors such as conflict may be differentially related to breakup among couples in which one versus both partners participated. These findings raise caution in interpreting effects found in dyadic studies and highlight the need to be mindful of potential bias in recruitment.
随着越来越多的关系研究依赖于对偶数据（即夫妻双方都是参与者），研究人员提出了这样的问题：这种样本是否代表了总体，或者在重要方面是否具有独特性。在这项研究中，我们使用了两个包含有和没有浪漫伴侣的参与者的大型数据集（研究 1：n=5118；研究 2：n=5194），以检验共同参与状态是否对关系有实质性的影响。研究结果表明，即使在控制了其他已知的预测因素（如满意度）之后，共同参与状态也能预测分手，尽管这种影响随着时间的推移而减弱（研究 2）。还有初步证据表明，冲突等因素可能与一方或双方参与的夫妻分手的关系不同。这些发现提醒人们在解释对偶研究中发现的影响时要谨慎，并强调需要注意招募过程中的潜在偏差。
