Suppressing the expression of negative emotions tends to undermine individuals' and their partners' wellbeing. However, sometimes expressive suppression may be relatively innocuous given that individuals commonly withhold negative emotions in order to maintain close relationships, and this may be especially the case when expressive suppression is enacted by people who exhibit amplified expressions of negative emotions, such as those high in attachment anxiety. The current research examined when and for whom expressive suppression may be more or less costly by testing whether the curvilinear effect of individuals' expressive suppression on individuals' and partners' outcomes is moderated by individuals' attachment anxiety. Our results across 3 dyadic studies revealed a linear effect of expressive suppression when predicting individuals' outcomes: greater expressive suppression had costs for individuals (lower relationship satisfaction, reported responsiveness and discussion success, and greater discussion threat). Furthermore, in 4 of the 5 models, a moderated curvilinear effect of expressive suppression emerged when predicting partners' outcomes. For individuals low in attachment anxiety, low levels of expressive suppression did not incur costs for their partners' relationship satisfaction, perceptions of individuals' responsiveness, discussion success, and discussion threat. Once expressive suppression surpassed moderate levels, however, greater expressive suppression had a detrimental effect on partners' outcomes. In contrast, for individuals high in attachment anxiety, the negative effect of moderate-to-high levels of expressive suppression on partners' outcomes was attenuated. These novel results demonstrate how considering curvilinear methods can uncover when and for whom expressive suppression may be more or less costly in intimate relationships.

依恋焦虑和表达抑制对个人和合作伙伴结果的曲线影响。

抑制负面情绪的表达往往会损害个人及其伴侣的幸福感。然而，有时表达抑制可能相对无害，因为个体通常会为了维持亲密关系而抑制负面情绪，尤其是当表达抑制是由表现出负面情绪表达放大的人实施时，例如那些高调的人。依恋焦虑。当前的研究通过测试个人表达抑制对个人和合作伙伴结果的曲线效应是否受到个人依恋焦虑的调节，来检查何时以及为谁表达抑制可能或多或少的成本。我们在 3 项二元研究中的结果揭示了在预测个人结果时表达抑制的线性效应：更大的表达抑制对个人有成本（较低的关系满意度、报告的响应性和讨论成功以及更大的讨论威胁）。此外，在 5 个模型中的 4 个模型中，在预测伴侣的结果时出现了表达抑制的适度曲线效应。对于依恋焦虑低的个体，低水平的表达抑制不会为其伴侣的关系满意度、个人反应的感知、讨论成功和讨论威胁带来成本。然而，一旦表达抑制超过中等水平，更大的表达抑制就会对伴侣的结果产生不利影响。相比之下，对于依恋焦虑高的个体，中到高水平的表达抑制对伴侣结果的负面影响减弱。这些新颖的结果表明，考虑曲线方法可以揭示何时以及为谁表达抑制在亲密关系中可能或多或少的成本。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
