: The Life Orientation Test-Revised (LOT-R) is often used to assess dispositional optimism. The aims of this study were to test psychometric properties of the LOT-R, to provide normative scores, and to test the association between optimism and several psychological, sociodemographic, and behavioral factors. : A randomly selected German general population community sample with an age range of 18-80 years ( = 9,711) was surveyed. : The Confirmatory Factor Analysis (CFA) proved two (correlated) factors: and . Invariance tests across gender and age groups confirmed metric invariance. There were only small gender differences in the LOT-R total score (= 16.4 for females and = 16.1 for males). The correlation between the subscales and was strong for young and well educated people. Low optimism mean scores were observed for unemployed people, people with low income, smokers, and obese people. Normative scores of the LOT-R are provided. : The study confirmed the bidimensional structure of the LOT-R and invariance across age and gender. We can recommend using this instrument for measuring dispositional optimism and pessimism in epidemiological research and clinical practice.
生活取向测试修订版（LOT-R）常用于评估气质性乐观。本研究的目的是检验LOT-R的心理测量特性，提供常模分数，并检验乐观与若干心理、社会人口学和行为因素之间的关联。：对年龄在18 - 80岁之间的德国普通人群社区随机样本（n = 9711）进行了调查。：验证性因素分析（CFA）证实了两个（相关的）因素：[此处原文缺失因素具体内容]和[此处原文缺失因素具体内容]。跨性别和年龄组的不变性检验证实了度量不变性。LOT-R总分仅存在微小的性别差异（女性为16.4，男性为16.1）。对于年轻且受过良好教育的人群，分量表[此处原文缺失分量表具体内容]和[此处原文缺失分量表具体内容]之间的相关性较强。观察到失业者、低收入者、吸烟者和肥胖者的乐观平均得分较低。提供了LOT-R的常模分数。：该研究证实了LOT-R的二维结构以及跨年龄和性别的不变性。我们建议在流行病学研究和临床实践中使用该工具来测量气质性乐观和悲观。
