Environment-friendly behaviors may be desirable in helping to solve worldwide ecological issues. This has sparked interest in the associations of such behaviors with established psychological constructs such as the Five-Factor Model personality traits. Of these, Openness has been most consistently linked with proenvironmental behavior; yet, the extent of causality in this association is unclear. Using a sample of 168 individuals, including 84 sibling pairs, the present study replicated the association while controlling for factors in which families differ (environmental factors that siblings share and a proportion of genetic variance). Proenvironmental behavior was correlated with Openness (r = .51) and the association could be observed both between (r = .57) and within families (r = .29), with adjustments for various demographic variables. These findings indicate that more open individuals tend to engage in proenvironmental behaviors, even when controlling for possibly confounding factors shared and not shared between siblings.

开放性与家庭内部和家庭之间的亲环境行为有关

环保行为可能有助于解决全球生态问题。这引起了人们对此类行为与已建立的心理结构（如五因素模型人格特质）之间关联的兴趣。其中，开放性与环保行为的联系最为一致；然而，这种关联的因果关系程度尚不清楚。本研究使用 168 个人的样本，包括 84 对兄弟姐妹，复制了这种关联，同时控制了家庭不同的因素（兄弟姐妹共享的环境因素和遗传变异的比例）。亲环境行为与开放性 (r = .51) 相关，并且可以在 (r = .57) 和家庭内部 (r = .29) 之间观察到这种关联，并对各种人口统计变量进行调整。
