本文概述了以前的工作影响变异性，讨论了影响变异性的研究方法上的缺陷，并提出了一个实证研究的结果，个体内变异的主要情绪随着时间的推移。日常评估研究的结果，使用结构方程模型和非线性回归分析表明，影响的个体内变异是一个多维的结构，是足够稳定，被认为是一种心理特征，可以可靠地测量的个体内标准差。个体内变异显示收敛效度与平均水平分数和神经质，但足够明显，被认为是一个独特的特质。积极情绪的个体内变异性尤其如此;只有大约10%的变异可以用平均情感水平和人格5因素模型的变量来解释。
This article gives an overview of previous work on affect variability, discusses the methodological shortcomings of research on affect variability, and presents the results of an empirical study of intraindividual variability in primary emotions across time. The results of a daily assessment study using structural equation modeling and nonlinear regression analyses showed that intraindividual variability in affect is a multidimensional construct that is sufficiently stable to be considered a psychological trait and can be reliably measured by the intraindividual standard deviation. Intraindividual variability showed convergent validity with mean level scores and neuroticism but was sufficiently distinct to be considered a unique trait. This was particularly true of intraindividual variability in positive emotions; only about 10% of the variance could be accounted for by mean affect levels and the variables of the 5-factor model of personality.
