Despite numerous meta-analyses, the true extent to which life satisfaction reflects personality traits has remained unclear due to overreliance on a single method to assess both and insufficient attention to construct overlaps. Using data from three samples tested in different languages (Estonian, N = 20,886; Russian, N = 768; English, N = 600), we combined self- and informant-reports to estimate personality domains' and nuances' true correlations (rtrue) with general life satisfaction (LS) and satisfactions with eight life domains (DSs), while controlling for single-method and occasion-specific biases and random error, and avoiding direct construct overlaps. The associations replicated well across samples. The Big Five domains and nuances allowed predicting LS with accuracies up to rtrue ≈ .80-.90 in independent (sub)samples. Emotional stability, extraversion, and conscientiousness correlated rtrue ≈ .30-.50 with LS, while its correlations with openness and agreeableness were small. At the nuances level, low LS was most strongly associated with feeling misunderstood, unexcited, indecisive, envious, bored, used, unable, and unrewarded (rtrue ≈ .40-.70). Supporting LS's construct validity, DSs had similar personality correlates among themselves and with LS, and an aggregated DS correlated rtrue ≈ .90 with LS. LS's approximately 10-year stability was rtrue = .70 and its longitudinal associations with personality traits mirrored cross-sectional ones. We conclude that without common measurement limitations, most people's life satisfaction is highly consistent with their personality traits, even across many years. So, satisfaction is usually shaped by these same relatively stable factors that shape personality traits more broadly. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

大多数人的生活满意度与其性格特征相匹配：多特征、多评估者、多样本数据中的真实相关性。


尽管进行了大量的荟萃分析，但由于过度依赖单一方法来评估两者，并且对构建重叠的关注不够，生活满意度反映人格特质的真实程度仍不清楚。使用以不同语言测试的三个样本的数据（爱沙尼亚语，N = 20,886；俄语，N = 768；英语，N = 600），我们结合自我报告和线人报告来估计人格领域和细微差别的真实相关性（rtrue）总体生活满意度（LS）和八个生活领域（DS）的满意度，同时控制单一方法和特定场合的偏差和随机误差，并避免直接的结构重叠。这些关联在样本中复制得很好。大五域和细微差别允许在独立（子）样本中以高达 rtrue ≈ .80-.90 的精度预测 LS。情绪稳定性、外向性和尽责性与 LS 相关性 rtrue ≈ .30-.50，而与开放性和宜人性的相关性很小。在细微差别层面上，低 LS 与感觉被误解、不兴奋、优柔寡断、嫉妒、无聊、被利用、无能为力和没有回报的感觉最密切相关（rtrue ≈ .40-.70）。 DS 之间以及与 LS 之间具有相似的个性相关性，并且聚合 DS 与 LS 的相关性 rtrue ≈ .90 支持 LS 的构造效度。 LS 的大约 10 年稳定性为 rtrue = 0.70，其与人格特质的纵向关联反映了横向关联。我们的结论是，如果没有共同的测量限制，大多数人的生活满意度与其人格特质高度一致，即使是在很多年里也是如此。因此，满意度通常是由这些相对稳定的因素决定的，这些因素更广泛地塑造了人格特质。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
