This study addresses the factor structure and psychometric properties of the Self-Report Family Inventory-Version II (SFI-II) for a Portuguese sample. Based on the Beavers Systems Model, the SFI-II is a brief screening instrument, with 36 items that measure family competence, family style and other related domains. The SFI-II and several criterion scales were administered to a heterogeneous sample of 1083 individuals with ages ranging from 12 to 83 years old. In contrast with the original five-factor structure, but aligned with more recent findings, factor analysis showed that two factors could be meaningfully extracted. Additionally, analyses suggest that the SFI-II is a valid and reliable measure of family functioning. The authors propose a critical reading of the scale’s bifactorial structure and its connection with the underlying theoretical model. The SFI-II appears to be a promising measure of family competence, with clinical and research applicability.

本研究针对葡萄牙样本解决了自我报告家庭量表 II (SFI-II) 的因素结构和心理测量特性。SFI-II基于Beavers Systems Model，是一个简短的筛选工具，有36个项目，衡量家庭能力、家庭风格和其他相关领域。SFI-II 和几个标准量表被用于 1083 名年龄从 12 岁到 83 岁不等的个体的异质样本。与最初的五因素结构相反，但与最近的发现一致，因素分析表明可以有意义地提取两个因素。此外，分析表明 SFI-II 是衡量家庭功能的有效且可靠的指标。作者建议对量表的双因素结构及其与基础理论模型的联系进行批判性解读。SFI-II 似乎是一种很有前途的家庭能力衡量标准，具有临床和研究适用性。
