The Dyadic Adjustment Scale (DAS; G. B. Spanier, 1976) is the most widely used inventory of relationship satisfaction in the social sciences, yet the question of whether it is measuring the same concept in men and women has never been addressed. In the current study, the authors examined the factor structure of the DAS in a sample of 900 currently married couples who participated in the Minnesota Twin Family Study. Confirmatory factor analysis was applied to a second-order factor solution with Spanier's four factors (Dyadic Consensus, Dyadic Satisfaction, Dyadic Cohesion, Affectional Expression) loading on one higher order factor (Relationship Adjustment), to test for measurement invariance across gender. The second-order solution was relatively invariant across gender, even when taking into account the nonindependent nature of the data. This suggests that the best conceptualization of the DAS is one of a gender-invariant measure of marital adjustment with four distinct subfactors and that differences between men and women on any of these constructs can be interpreted by both clinicians and researchers as true mean differences rather than measurement bias.
对偶调整量表（DAS；G. B. Spanier，1976 年）是社会科学中使用最广泛的关系满意度量表，但它是否在男性和女性中测量相同的概念从未得到解决。在当前的研究中，作者在参与明尼苏达州双胞胎家庭研究的 900 对已婚夫妇样本中检验了 DAS 的因子结构。验证性因子分析应用于二阶因子解决方案，其中 Spanier 的四个因素（对偶共识、对偶满意度、对偶凝聚力、情感表达）加载在一个更高阶的因素（关系调整）上，以测试性别之间的测量不变性。二阶解决方案在性别上相对不变，即使考虑到数据的非独立性。这表明，DAS 的最佳概念化是一种性别不变的婚姻调整衡量标准，具有四个不同的子因素，并且男性和女性在任何这些结构上的差异都可以被临床医生和研究人员解释为真正的均值差异，而不是测量偏差。
