How should romantic-relationship quality be approached psychometrically? This is a complicated theoretical and methodological challenge that we begin to address through three studies. In Study 1a, we identified 25 distinct romantic-relationship categories among 754 items from 26 romantic-relationship-quality instruments with a weak Jaccard index (0.38), indicating that the scales' item content was extremely heterogeneous. Study 1b then demonstrated limited structure validity evidence in 43 scale-development-validation articles of 23 of these 26 instruments. Finally, Study 2 surveyed 587 French-speaking participants in a romantic relationship on romantic-relationship quality. Applying a network-based model, we identified four dimensions, three of which are central to relationship quality. The inferences were mostly limited to French-speaking, monogamous, heterosexual women. To resolve challenges detected in the literature, we recommend a multicountry qualitative approach, more diverse sampling, better definitions of romantic-relationship quality, and a dynamic-systems approach to measuring romantic-relationship quality.

一种基于网络的评估浪漫关系质量的新颖方法。


应该如何从心理测量的角度来衡量恋爱关系的质量？这是一个复杂的理论和方法论挑战，我们开始通过三项研究来解决。在研究 1a 中，我们从 26 个浪漫关系质量工具的 754 个项目中确定了 25 个不同的浪漫关系类别，杰卡德指数较弱（0.38），表明量表的项目内容极其异质。然后，研究 1b 在这 26 种工具中的 23 种的 43 篇量表开发验证文章中证明了有限的结构有效性证据。最后，研究 2 对 587 名法语浪漫关系参与者的浪漫关系质量进行了调查。应用基于网络的模型，我们确定了四个维度，其中三个对于关系质量至关重要。这些推论大多局限于讲法语、一夫一妻制的异性恋女性。为了解决文献中发现的挑战，我们建议采用多国定性方法、更多样化的抽样、更好的浪漫关系质量定义以及衡量浪漫关系质量的动态系统方法。
