Background: Family quality of life (FQoL), just like individual quality of life, has become a priority outcome in the policies and services received by persons with intellectual and developmental disabilities (IDD) and their families. Conceptualizing, measuring, and theorizing FQoL has been the object of investigation in recent decades. The goal of this paper is to present a revision of the Spanish Family Quality of Life Scales, the CdVF-E < 18 and the CdVF-E >18, and describe the FQoL of Spanish families with a member with IDD. Methods: The sample included a total of 548 families with a member under 18 years old and 657 families with a member over 18. Based on an Exploratory Factor Analysis (EFA) firstly and a Confirmatory Factor Analysis (CFA) secondly, the two scales’ psychometric properties were explored. Results: The CdVF-ER < 18 and the CdVF-ER > 18 comprise 5 dimensions, containing 35 and 32 items, respectively, and they show good validity and reliability. The families obtained a high FQoL score, although some differences exist between the dimensions on which families with children under and over 18 score highest and lowest. Conclusion: The characteristics of the revised scales facilitate their use by professionals, administrations, and services.

18岁及以下的西班牙家庭生活质量量表：心理计量特性和家庭观念

背景：与个人生活质量一样，家庭生活质量（FQoL）已成为智障和发展性残疾人（IDD）及其家人所接受的政策和服务的优先结果。FQoL的概念化，测量和理论化是近几十年来的研究对象。本文的目的是提出西班牙家庭生活质量量表的修订版，CdVF-E <18和CdVF-E> 18，并描述具有IDD成员的西班牙家庭的FQoL。方法：样本共包括548个18岁以下成员的家庭和657个18岁以上成员的家庭。首先根据探索性因素分析（EFA），然后基于确认性因素分析（CFA），采用两个量表。心理测量特性进行了探讨。结果：CdVF-ER < 18和CdVF-ER> 18包含5个维度，分别包含35和32个项目，它们显示出良好的有效性和可靠性。这些家庭获得了较高的FQoL分数，尽管18岁以下和18岁以上儿童的家庭在最高和最低得分方面存在一定差异。结论：修订后的量表的特点有助于专业人员，主管部门和服务机构使用它们。
