In recent decades, there has been a rapid increase in immigration rates throughout Europe, and many immigrants remained permanently. As a result, a substantial part of society are second-generation immigrants. Despite an increase in research related to this population, predominantly from the US, it remains unknown, whether growing up and living in two cultures fosters immigrants’ subjective well-being. The present study investigated the association between acculturation (here heritage and mainstream culture orientation) and subjective well-being of second-generation immigrants in Switzerland. We further ran a multigroup analyses for women and men separately. Data of N = 492 adult children of immigrants (66% women; M_age = 32.39, SD_age = 10.46) were analyzed. Structural equation modelling showed that both orientation toward heritage and toward mainstream culture were positively related to subjective well-being, and that this was moderated by gender. Furthermore, the interaction between both kinds of orientation had a significant effect on subjective well-being. The study addresses several gaps in the existing research literature in three key ways: (1) it adds a European perspective; (2) it focuses on understudied second-generation immigrants; (3) it measures acculturation bilinear and multidimensional, as is required theoretically. Moreover, the findings may contribute to a more nuanced public discourse, where the significance of both mainstream orientation and heritage culture is occasionally called into question.

近几十年来，整个欧洲的移民率迅速上升，许多移民永久居留。因此，社会的很大一部分是第二代移民。尽管与这一人群相关的研究有所增加（主要来自美国），但在两种文化中成长和生活是否会促进移民的主观幸福感仍然未知。本研究调查了瑞士第二代移民的文化适应（这里指遗产和主流文化取向）与主观幸福感之间的关系。我们进一步分别对女性和男性进行了多组分析。对N = 492 名成年移民子女（66% 为女性； M_年龄= 32.39， SD_年龄= 10.46）的数据进行了分析。结构方程模型表明，对遗产和主流文化的取向都与主观幸福感呈正相关，并且这一点受到性别的调节。此外，两种取向之间的相互作用对主观幸福感有显着影响。该研究通过三个关键方式弥补了现有研究文献中的几个空白：（1）增加了欧洲视角； (2) 重点关注未被充分研究的第二代移民； （3）它按照理论要求测量双线性和多维的文化适应。此外，这些发现可能有助于更加细致的公众讨论，主流导向和传统文化的重要性偶尔会受到质疑。
