BACKGROUND
This study analyzes the psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q; Quality of Life Questionnaire Manual - 1993 Manual and 2004 Revision. 2004, IDS Publishing Company, Worthington, OH; Schalock & Keith 2004).
METHOD
The analysis of the factorial structure was carried out on a sample of 304 adults with intellectual disabilities, through the use of confirmatory (CFA) and exploratory (EFA) factor analysis. The relationships of the QOL-Q with life satisfaction and self-concept measures were determined in groups composed of respectively 72 and 78 adults with intellectual disabilities.
RESULTS
Confirmatory factorial analysis indicated a poor adjustment of the original factor structure to the Portuguese data. EFA indicated the existence of four factors, which include 30 items, and that were also supported by CFA. The total score of the QOL-Q revealed a reduced correlation with life satisfaction, and a moderate correlation with the self-concept.
CONCLUSIONS
The Portuguese version of the QOL-Q shows satisfactory psychometric properties, but also some limitations.
背景
本研究分析了生活质量问卷（QOL-Q；生活质量问卷手册-1993 年手册和 2004 年修订版。2004 年，IDS 出版公司，沃辛顿，OH；Schalock & Keith 2004）的葡萄牙语版本的心理测量特性。
方法
通过使用验证性（CFA）和探索性（EFA）因子分析，对 304 名智力残疾成年人的样本进行了因子结构分析。在分别由 72 名和 78 名智力残疾成年人组成的组中，确定了 QOL-Q 与生活满意度和自我概念测量的关系。
结果
验证性因子分析表明，原始因子结构对葡萄牙数据的调整效果不佳。EFA 表明存在包含 30 个项目的四个因子，这也得到了 CFA 的支持。QOL-Q 的总分与生活满意度的相关性降低，与自我概念的相关性适中。
结论
QOL-Q 的葡萄牙语版本具有令人满意的心理测量特性，但也存在一些局限性。
