This study assessed the measurement invariance of selected self-report measures of perfectionism, impulsivity, self-esteem and social anxiety in samples of emerging adults from eight different countries. Participants (N = 6272) completed the Multidimensional Perfectionism Scale (MPS), the UPPS-P Impulsive Behavior Scale, the 5-item Rosenberg Self-Esteem Scale (5-item RSES) and the Social Interaction Anxiety Scale (SIAS-6). Multigroup confirmatory factor analysis was run to examine cross-measure equivalence. Evidence for structural invariance was found for all questionnaires, while weak invariance was supported only for the 5-item RSES and the SIAS-6, and a partial weak invariance was found for the MPS and the UPPS-P. No measure achieved strong invariance. Strict invariance was achieved for the 5-item RSES, whereas only a partial strict invariance was supported for the MPS, UPPS-P and SIAS-6. These results suggest that perfectionism, impulsivity, self-esteem, and social anxiety are subjected to linguistic/cultural influence as well as to the effects of socio-demographic variables and can be evaluated by using the selected measures in eight different countries worldwide - but results should be interpreted with caution.
本研究评估了来自八个不同国家的青年样本中选择的完美主义、冲动、自尊和社交焦虑的自我报告测量的测量不变性。参与者（N=6272）完成了多维完美主义量表（MPS）、UPPS-P 冲动行为量表、5 项罗森伯格自尊量表（5 项 RSES）和社交互动焦虑量表（SIAS-6）。进行了多组验证性因素分析以检查跨测量等效性。所有问卷都发现了结构不变性的证据，而只有 5 项 RSES 和 SIAS-6 支持弱不变性，MPS 和 UPPS-P 则支持部分弱不变性。没有一个测量指标达到强不变性。5 项 RSES 达到了严格不变性，而 MPS、UPPS-P 和 SIAS-6 仅支持部分严格不变性。这些结果表明，完美主义、冲动、自尊和社交焦虑受到语言/文化影响以及社会人口变量的影响，可以在全球八个不同国家使用选定的措施进行评估——但结果应谨慎解释。
