Abstract

Marital satisfaction is considered a core dimension to understand marriage quality, influencing individual and family well-being. The Kansas Marital Satisfaction Scale (KMSS) is one of the most used instruments to assess this dimension. This study presents the psychometric properties of the KMSS Portuguese version through two studies. In Study 1, 145 couples (parents of school-aged children) completed the KMSS, and the Co-parenting Questionnaire and Inventory of Attachment in Childhood and Adolescence. The one-factor structure of the KMSS was supported (CFA), and an invariance analysis showed the same structure for males and females. Preliminary evidence supported concurrent and discriminant validity, and high reliability (α = .97) was observed. In Study 2, the factor structure was replicated in an extended sample (361 couples) and invariance tests showed a similar one-factor structure for two stages of the family life cycle (children 6–12 and 13–18 years). Results indicated the measure’s suitability for research in the Portuguese context; however, further study is needed for its clinical use.

摘要

婚姻满意度被认为是了解婚姻质量、影响个人和家庭幸福的核心维度。堪萨斯婚姻满意度量表 (KMSS) 是评估这一维度最常用的工具之一。本研究通过两项研究展示了 KMSS 葡萄牙语版本的心理测量特性。在研究 1 中，145 对夫妇（学龄儿童的父母）完成了 KMSS、共同养育问卷和儿童和青春期依恋清单。KMSS 的单因素结构得到支持 (CFA)，不变性分析显示男性和女性的结构相同。初步证据支持并发效度和判别效度以及高信度（α= .97) 观察到。在研究 2 中，因子结构在扩展样本（361 对夫妇）中复制，不变性检验显示家庭生命周期的两个阶段（6-12 岁和 13-18 岁儿童）具有相似的单因子结构。结果表明该措施适用于葡萄牙语环境中的研究；但其临床应用尚需进一步研究。
