Instruments aimed to investigate general aspects of quality of life are scarce in the literature. Flanagan's Quality of Life Scale (QoLS) is an alternative instrument which provides a more comprehensive evaluation of quality of life in different contexts.
To investigate some psychometric properties of the QoLS and discuss the measurement of quality of life using this scale in heterogeneous and large populations.
The QoLS comprises 16 items divided into five dimensions. Responses were measured using a 7-point rating scale. Data were collected from a stratified sample of primary health care users in the municipality of Ribeirão Preto, state of São Paulo, Brazil. Polychoric correlation matrix and exploratory and confirmatory factor analyses were performed.
A total of 1,054 primary health care users in 12 health care facilities were interviewed: 79.7% female; mean age = 36.97 years (standard deviation = 15.1). Moderate to low correlation coefficients were observed between almost all pairs of QoLS items. Items 7 and 9 as well as items 14 and 15 were the pairs presenting the highest correlation coefficient. The original structure of the QoLS, with five dimensions, showed adequate psychometric properties regarding the data collected. The inclusion of a single item on life satisfaction was proposed.
The original structure of the QoLS was validated and found to be reliable when applied to primary health care users. A new general item was suggested for future studies to improve the interpretations and associations regarding general aspects of quality of life in large and heterogeneous populations.
旨在调查生活质量总体方面的工具在文献中较为稀缺。弗拉纳根生活质量量表（QoLS）是一种可供选择的工具，它能在不同背景下对生活质量进行更全面的评估。
研究QoLS的一些心理测量特性，并讨论在异质性大群体中使用该量表测量生活质量的情况。
QoLS由16个项目组成，分为五个维度。使用7点量表来测量回答。数据收集自巴西圣保罗州里贝朗普雷图市初级卫生保健使用者的分层样本。进行了多列相关矩阵以及探索性和验证性因素分析。
对12个卫生保健机构的1054名初级卫生保健使用者进行了访谈：79.7%为女性；平均年龄 = 36.97岁（标准差 = 15.1）。几乎所有QoLS项目对之间的相关系数均为中等到低等。项目7和9以及项目14和15是相关系数最高的项目对。QoLS的原始五维度结构在收集的数据方面显示出足够的心理测量特性。建议纳入一个关于生活满意度的单一项目。
QoLS的原始结构经过验证，发现应用于初级卫生保健使用者时是可靠的。建议在未来研究中增加一个新的总体项目，以改进对异质性大群体生活质量总体方面的解释和关联。
