With the increasing diversity of the German population, it is important to test the psychometric validity and reliability of the German version Perceived Stress Scale (PSS-10) specifically between German natives and residents with a migration background. Using nationally representative data (N = 2527), this study conducted an Exploratory Factor Analysis (EFA) to determine the most appropriate factor structure, a Multi-Group Confirmatory Factor Analysis (MGCFA) to compare the validity of the two-factor structure and tested the PSS-10 measurement invariance between the German native and migrant sub-samples. Lastly, reliability of the PSS-10 was examined via Cronbach’s alpha, omega and individual item analyses across the two sub-samples. The EFA results support a two-factor structure in the migrant sample. The MGCFA showed adequate model fit for both sub-samples and the PSS-10 is strict invariant between German natives and migrants. Cronbach’s alpha and omega for Perceived Helplessness (PHS: factor 1) and Perceived Self-Efficacy (PSES: factor 2) demonstrate good internal consistency in both German and migrant sub-samples. The key conclusions are: (1) the German version PSS-10 is suitable for German residents with a migration background. (2) Despite good internal consistency for the total scale, the PSS-10 measures two aspects: (a) perceived helplessness and (b) perceived self-efficacy. Future research would profit from analyzing the two subscales separately, not only using the total score.

移民和德国本地人的感知压力量表(PSS-10)心理测量特性。

随着德国人口多样性的增加,重要的是测试德语版本的感知压力量表(PSS-10)的心理计量效度和可靠性,尤其是在德国本地人和具有移民背景的居民之间。使用全国代表性数据(N = 2527),本研究进行了探索性因素分析(EFA)以确定最合适的因素结构,进行了多组确认性因素分析(MGCFA)来比较两因素结构的有效性并进行了测试德国本地样本和移民子样本之间的PSS-10测量不变性。最后,通过Cronbach的alpha,Ω和两个子样本中的单个项目分析检查了PSS-10的可靠性。全民教育结果支持移民样本中的两因素结构。MGCFA对两个子样本都显示出足够的模型拟合,而PSS-10在德国本地人和移民之间是严格不变的。克伦巴赫的感知无助感(PHS:因子1)和感知自我效能感(PSES:因子2)的alpha和omega在德国和移民子样本中均表现出良好的内部一致性。主要结论是:(1)德文版PSS-10适用于具有移民背景的德国居民。(2)尽管总体规模内部具有良好的一致性,但PSS-10还是从两个方面进行衡量:(a)感知到的无助感和(b)感知到的自我效能感。未来的研究将受益于分别分析两个分量表,而不仅仅是使用总分。因素1)和感知的自我效能感(PSES:因素2)在德国和移民子样本中均表现出良好的内部一致性。主要结论是:(1)德文版PSS-10适用于具有移民背景的德国居民。(2)尽管总体规模内部具有良好的一致性,但PSS-10还是从两个方面进行衡量:(a)感知到的无助感和(b)感知到的自我效能感。未来的研究将受益于分别分析两个分量表,而不仅仅是使用总分。因素1)和感知的自我效能感(PSES:因素2)在德国和移民子样本中均表现出良好的内部一致性。主要结论是:(1)德文版PSS-10适用于具有移民背景的德国居民。(2)尽管总体规模内部具有良好的一致性,但PSS-10还是从两个方面进行衡量:(a)感知到的无助感和(b)感知到的自我效能感。未来的研究将受益于分别分析两个分量表,而不仅仅是使用总分。(a)感觉到的无助和(b)感觉到的自我效能感。未来的研究将受益于分别分析两个分量表,而不仅仅是使用总分。(a)感觉到的无助和(b)感觉到的自我效能感。未来的研究将受益于分别分析两个分量表,而不仅仅是使用总分。
