Couple satisfaction has been extensively investigated, but little attention has been paid to the nature and assessment of high-quality, flourishing couple relationships. Particularly, current measures of relationship quality are insensitive at the upper end of the continuum, which in turn hinders progress toward understanding and facilitating flourishing couple relationships. Drawing on concepts developed in positive psychology, we proposed a theoretical framework of couple flourishing that incorporates hedonic and eudemonic components. Items to assess these aspects of couple flourishing were generated and administered online to a sample of 1,116 participants. Using combined methods of classical test theory and item response theory (IRT), we selected the most informative items to form 4-, 8-, 16-item versions of a Couple Flourishing Measure (CFM). IRT analyses show that the CFM discriminated variation at the upper range of relationship quality better than widely used measures of relationship satisfaction. Confirmatory factor analysis showed that couple flourishing was related to, but distinguishable from, relationship satisfaction. In an independent sample of 330 participants, we replicated the unifactorial structure of the CFM, and the distinguishability of couple flourishing from couple satisfaction. This research offers new insight into the concept of relationship flourishing. The sensitivity of the CFM at the high end of relationship quality makes it possible to test for predictors of relationship flourishing and evaluate interventions that seek to enhance flourishing.

夫妇蓬勃发展的措施

夫妻满意度已被广泛调查，但很少关注高质量、蓬勃发展的夫妻关系的性质和评估。特别是，当前对关系质量的衡量在连续体的上端是不敏感的，这反过来又阻碍了理解和促进蓬勃发展的夫妻关系的进展。借鉴积极心理学中发展的概念，我们提出了一个结合享乐和幸福成分的夫妻繁荣理论框架。生成并在线管理 1,116 名参与者样本以评估夫妻繁荣的这些方面的项目。使用经典测试理论和项目反应理论 (IRT) 的组合方法，我们选择了信息量最大的项目，以形成夫妻繁荣测量 (CFM) 的 4、8、16 个项目版本。IRT 分析表明，与广泛使用的关系满意度衡量标准相比，CFM 能够更好地区分关系质量上限的变化。验证性因素分析表明，夫妻的繁荣与关系满意度有关，但与关系满意度有区别。在 330 名参与者的独立样本中，我们复制了 CFM 的单因素结构，以及夫妻繁荣与夫妻满意度的区别。这项研究为关系繁荣的概念提供了新的见解。CFM 在关系质量高端的敏感性使得测试关系繁荣的预测因素和评估寻求促进繁荣的干预措施成为可能。
