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.
