可靠性系数，如测试-重测相关性，量化了测试分数中的瞬时误差，这是由于特定于考试的变化，例如，当前的情绪或感觉。荟萃分析总结了在长达两个月的时间间隔内从74个样本（总N = 14，923）中收集的682个重测相关性，这些样本跨越了大五的不同测量。这五个特征的平均可靠性估计值为rho（tt）= 0.816。外向性量表导致最可靠的分数，而宜人性量表表现出稍大的测量误差。瞬时误差约占大五人格分数观察到的方差的10%。元回归分析表明，所选择的重测间隔对三个性状的调节作用较小，较短的间隔导致较高的重测相关性。(C)2014爱思唯尔公司All rights reserved.
Dependability coefficients such as test-retest correlations quantify transient error in test scores due to occasion-specific variations in, for example, current mood or feelings. The meta-analysis summarizes 682 test-retest correlations collected within an interval of up to two months from 74 samples (total N = 14,923) across different measures of the Big Five. The median aggregated dependability estimate for the five traits was rho(tt) = .816. Extraversion scales resulted in the most dependable scores, whereas agreeableness scales exhibited slightly larger measurement error. Transient error accounted for about 10% of the observed variance in scores of the Big Five. Meta-regression analyses indicated small moderation effects of the chosen retest interval for three traits, with shorter intervals resulting in higher retest correlations. (C) 2014 Elsevier Inc.
