非共享环境影响在成年之前仅表现出最小的稳定性。然而，大多数纵向双胞胎研究的特点是评估滞后较长（通常为 3-5 年），这使得解释这些结果变得困难。为了更严格地评估成年之前的非共享环境稳定性，我们将生物统计相关因素模型拟合到：1）239对16-25岁双胞胎中连续7天的自我报告的消极和积极影响，2）687对6-10岁双胞胎中连续7分钟的观察者评价的温暖和控制。然后，我们使用类似于单向方差分析的混合效应，凭经验检查了病因学稳定性随时间变化的模式。研究发现，遗传和共享环境的相关性在几天和几分钟内都高度稳定。相比之下，非共享环境相关性随着滞后长度的增加而单调下降，而且，当检查时间间隔长于几分钟时，非共享环境相关性的幅度为小到中等。这些发现意味着非共享环境可能主要由成年之前的短暂和特殊影响组成。
Non-shared environmental influences show only minimal stability over time prior to adulthood. The long assessment lags (typically 3-5 years) that characterize most longitudinal twin studies, however, make it difficult to interpret these results. To more rigorously evaluate non-shared environmental stability prior to adulthood, we fitted biometric correlated factors models to 1) seven consecutive days of self-reported negative and positive affect in 239 twin pairs aged 16-25 years and 2) seven consecutive minutes of observer rated warmth and control in 687 twin pairs aged 6-10 years. We then empirically examined patterns of etiologic stability over time using a mixed effects analog to the one-way ANOVA. Genetic and shared environmental correlations were found to be highly stable over both days and minutes. By contrast, non-shared environmental correlations decreased monotonically with increasing lag length, and moreover, were small-to moderate in magnitude when examining intervals longer than a few minutes. Such findings imply that the non-shared environment may be comprised primarily of transient and idiosyncratic effects prior to adulthood.
