Perfectionism can be understood as a personality trait that establishes excessively high standards for the performance of individuals and ostensibly critical self-evaluations. It is associated with a range of variables, such as anxiety, suicidal tendencies, depression, and low satisfaction with life. The Short Almost Perfect Scale (SAPS) overcame some limitations of previous measures (e.g., ambiguity, nonnecessary factors). In the present research, we provide psychometric evidence of the adequacy of the SAPS in Brazil. The original two-factor structure was replicated. The items showed good discrimination, level of difficulty, and informativeness for the overall measure. The SAPS also presented acceptable reliability levels, full measurement invariance across participants’ gender, and partial invariance across countries (Brazil and the United States). Finally, perfectionism was meaningfully associated with personality traits and human values. In sum, our findings suggest that the SAPS is psychometrically adequate for further use in Brazil.

巴西短期几乎完美量表 (SAPS) 的心理测量证据

完美主义可以理解为一种人格特质，它对个人的表现和表面上的批判性自我评价建立了过高的标准。它与一系列变量有关，例如焦虑、自杀倾向、抑郁和对生活的低满意度。短期几乎完美量表 (SAPS) 克服​​了先前措施的一些局限性（例如，歧义、非必要因素）。在目前的研究中，我们提供了巴西 SAPS 充分性的心理测量证据。复制了原始的双因子结构。这些项目在整体测量中表现出良好的辨别力、难度和信息量。SAPS 还提供了可接受的可靠性水平、跨参与者性别的完全测量不变性、和不同国家（巴西和美国）的部分不变性。最后，完美主义与人格特质和人类价值观有意义地联系在一起。总之，我们的研究结果表明 SAPS 在心理测量上足以在巴西进一步使用。
