Normative data for WHOQOL-bref are scarce in the literature and unavailable in Latin American countries. The main objective of this study was to provide normative scores of WHOQOL-bref in a general population sample in Brazil and to describe differences in mean scores according to some socio-demographic characteristics.
WHOQOL-bref was applied to a randomly selected sample of the general population of Porto Alegre. Participants were literate people aged 20 to 64 years. The questionnaires were self-administered in the presence of an interviewer in the respondent's home.
The response rate was 68%, and the final sample contained 751 respondents (38% men, 62% women). Low quality of life was observed in the following subgroups: female gender, lower economic class, lower educational level, and the subgroup reporting a chronic medical condition. The mean scores of the WHOQOL-bref and percentiles of scores are reported as normative data for the general population.
Our results can be useful to researchers using the WHOQOL-bref to compare their results with normative data from a randomly selected sample of general population. Additionally, the ability of WHOQOL-bref to discriminate different population subgroups makes it an important tool to identify vulnerable groups in epidemiological surveys.
世界卫生组织生活质量简表（WHOQOL-bref）的常模数据在文献中较为匮乏，在拉丁美洲国家更是无法获取。本研究的主要目的是为巴西的一般人群样本提供 WHOQOL-bref 的常模评分，并根据一些社会人口学特征描述平均得分的差异。
WHOQOL-bref 应用于随机抽取的巴西阿雷格里港一般人群样本。参与者为 20 至 64 岁的识字人群。问卷由受访者在家中在访谈者的陪同下进行自填。
应答率为 68%，最终样本包含 751 名受访者（38%为男性，62%为女性）。在以下亚组中观察到生活质量较低：女性、较低经济阶层、较低教育水平，以及报告患有慢性疾病的亚组。报告了 WHOQOL-bref 的平均得分和得分百分位数，作为一般人群的常模数据。
我们的结果可用于研究人员，将其结果与随机抽取的一般人群样本的常模数据进行比较。此外，WHOQOL-bref 能够区分不同的人群亚组，使其成为在流行病学调查中识别弱势群体的重要工具。
