In this paper, we examined the psychometric properties of the English and French versions of the Multidimensional Psychological Flexibility Inventory short form (MPFI-24). Study 1 was conducted in the United States among the general population (N = 2668) to assess the reliability and factorial validity of the English version. In Study 2, the MPFI-24 was translated in French and tested among a population of French-speaking university students (N = 728) from Canada and France to assess its reliability as well as its factorial and convergent validity. Study 3 was conducted among French-speaking employees (N = 450) from Canada, France, Belgium, Switzerland and Luxembourg to test the concurrent validity of the French version and explore its pattern of correlations with various mental health indicators (burnout, psychological wellbeing, psychological distress and work satisfaction). Confirmatory factor analysis showed that both versions rely on a 2 s-order factors structure encompassing six first-order factors of flexibility and six first-order factors of inflexibility. Both versions have good internal consistency, convergent and concurrent validity. Taken together, these findings suggest that the MPFI-24 is a short, reliable and valid measure of psychological flexibility and inflexibility.

在本文中，我们研究了多维心理灵活性清单简称（MPFI-24）的英语和法语版本的心理测量特性。研究1在美国的普通人群中进行（N  = 2668），以评估英语版本的信度和阶乘有效性。在研究2中，MPFI-24被翻译成法语，并在 来自加拿大和法国的一群法语大学生（N = 728）中进行了测试，以评估其可靠性以及阶乘和收敛的有效性。研究3是在讲法语的员工中进行的（N = 450）来自加拿大，法国，比利时，瑞士和卢森堡，以测试法语版本的并发有效性，并探讨其与各种心理健康指标（倦怠，心理健康，心理困扰和工作满意度）的相关关系。验证性因素分析表明，两个版本都依赖于2 s阶因素结构，其中包括六个一阶灵活性因素和六个一阶刚性因素。两种版本都具有良好的内部一致性，收敛性和并发有效性。综上所述，这些发现表明MPFI-24是心理柔韧性和僵硬性的简短，可靠和有效的量度。
