Addressing potential weaknesses in an earlier investigation, the authors examined the latent structure of marital discord using 4 product indicators from the Marital Satisfaction Inventory-Revised (Snyder, 1997) in a representative sample of community couples (N = 1,020). Results from 3 taxometric procedures suggested that marital discord is taxonic, with an estimated base rate of .31. Cut scores for classifying members of this marital discord taxon were identified. Additional analyses with several data sets of community and clinic couples provided evidence that the marital discord taxon classification demonstrated good (a) 6-week test-retest reliability, (b) criterion validity (i.e., differences in taxon prevalence in community vs. clinic couples), and (c) construct validity (i.e., correlations with therapist ratings of relationship quality). These results suggest that discordant couples differ qualitatively and not just quantitatively from nondiscordant couples and that user friendly methods, suitable for a range of research and clinical applications, can be used to identify marital discord.
针对早期一项调查中的潜在弱点，作者在一个具有代表性的社区夫妻样本（N = 1020）中，使用修订后的婚姻满意度量表（Snyder，1997）中的4个乘积指标，研究了婚姻不和的潜在结构。3种分类分析程序的结果表明，婚姻不和是可分类的，估计基础率为0.31。确定了用于对该婚姻不和分类群体成员进行分类的临界分数。对社区和诊所夫妻的几个数据集进行的额外分析提供了证据，表明婚姻不和分类群体分类显示出良好的（a）6周重测信度，（b）效标效度（即社区夫妻与诊所夫妻中分类群体患病率的差异），以及（c）结构效度（即与治疗师对关系质量的评分的相关性）。这些结果表明，不和的夫妻与非不和的夫妻在质上存在差异，而不仅仅是量上的差异，并且适用于一系列研究和临床应用的用户友好方法可用于识别婚姻不和。
