Family quality of life (FQoL) constitutes an important aspect of early intervention. However, the culture bound nature of this construct necessitates validation of FQoL measures when being used in a culture different from the one in which they were developed. This study sought to understand the psychometric properties and construct validity of the Beach Center FQoL (BCFQoL) scale in Singapore. Data from 307 caregivers of children in an early intervention program were used. These caregivers completed the BCFQoL scale and external validity measures of family outcomes, psychological distress, and life situation. Confirmatory factor analysis and correlations were used to examine the factor structure and convergent and discriminant validity of the BCFQoL scale. Results indicated support for 5 FQoL dimensions and a higher-order FQoL factor. External convergent and discriminant validity, as well as internal statistical discriminant validity of the individual BCFQoL dimensions were supported. Despite evidence of internal statistical discriminant validity, there was little variation in the strength of the relationships between individual BCFQoL dimensions and the various external validity measures. Overall, the results of this study support the use of the BCFQoL scale as a valid measure of FQoL in Singapore.

新加坡海滩中心家庭生活质量量表的构建、收敛和判别效度

家庭生活质量 (FQoL) 是早期干预的一个重要方面。然而，这种结构的文化约束性质需要在 FQoL 测量值用于与它们开发的文化不同的文化中时进行验证。本研究旨在了解新加坡海滩中心 FQoL (BCFQoL) 量表的心理测量特性和结构效度。使用了早期干预计划中 307 名儿童看护者的数据。这些护理人员完成了 BCFQoL 量表和家庭结果、心理困扰和生活状况的外部效度测量。验证性因素分析和相关性用于检查 BCFQoL 量表的因素结构以及收敛和区分效度。结果表明支持 5 个 FQoL 维度和一个更高阶的 FQoL 因子。支持个体 BCFQoL 维度的外部收敛和判别效度以及内部统计判别效度。尽管有内部统计区分效度的证据，但个人 BCFQoL 维度与各种外部效度度量之间的关系强度几乎没有变化。总的来说，这项研究的结果支持在新加坡使用 BCFQoL 量表作为 FQoL 的有效衡量标准。
