The current study developed the European Portuguese version of the Psy-Flex. Its factor structure was studied through confirmatory factor analysis in a large community sample (N = 700) and cross-validated in calibration and validation samples created from the original sample. Confirmatory factor analyses confirmed a sample and sex-invariant single-factor structure with a very good fit to the data. These analyses supported good reliability and test-retest reliability in the PsyFlex European Portuguese version. Correlations with related and unrelated constructs were indicative of convergent and predictive validity. Because it is short and easy-to-use, it reduces participant burden and may be useful in clinical and research settings. The European Portuguese Psy-Flex version will allow the broadening of research possibilities not only in Portugal but also across cultural contexts.

评估成人的心理灵活性和心理健康：Psy-Flex 欧洲葡萄牙语版本

目前的研究开发了 Psy-Flex 的欧洲葡萄牙语版本。通过对大型社区样本 (N = 700) 进行验证性因素分析来研究其因素结构，并在从原始样本创建的校准和验证样本中进行交叉验证。验证性因素分析证实了样本和性别不变的单因素结构，与数据非常吻合。这些分析支持 PsyFlex 欧洲葡萄牙语版本具有良好的可靠性和重测可靠性。相关和不相关结构的相关性表明收敛和预测的有效性。由于它简短且易于使用，因此减少了参与者的负担，并且可能在临床和研究环境中有用。欧洲葡萄牙语 Psy-Flex 版本将不仅在葡萄牙，而且在跨文化背景下扩大研究的可能性。
