This research aimed to translate the original English version of the Psy-Flex, a scale of psychological flexibility, into Chinese and to test its psychometric properties among parents of children with autism spectrum disorder (ASD). Two phases were conducted: (1) translation from English to Chinese (Psy-Flex-C), followed by a semantic equivalence evaluation between two versions, a pre-test, and an evaluation of the Psy-Flex-C in terms of face validity with 20 parents of autistic children, and content validity of the Psy-Flex-C with eight experts. (2) A cross-sectional study with 248 parents of autistic children was conducted for validation, and a subgroup of 50 participants was randomly selected to assess the test-retest reliability at a 2-week interval. The Psy-Flex-C showed satisfactory semantic equivalence with the original version and demonstrated adequate internal consistency (Cronbach's α = 0.84) and test-retest stability (weighted kappa statistic = 0.88). Concurrent validity was supported by a moderate correlation between the Psy-Flex-C and the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (Pearson's r = 0.54, p < 0.01). The Psy-Flex-C showed a significant mean score difference between parents with high and low parenting stress (t = 5.43, p < 0.001). Similar to the original scale, confirmatory factor analysis showed the best fitting one-factor structure of the Psy-Flex-C (X/df = 1.62, p = 0.13, RMSEA = 0.05, GFI = 0.99, CFI = 0.99, TLI = 0.98, SRMR = 0.023). The Psy-Flex-C can be a reliable and valid instrument to self-report psychological flexibility in parents of children with ASD. Future research is recommended to test the Psy-Flex-C using diverse samples from different cultures and contexts to enhance its generalizability.
本研究旨在将心理灵活性量表Psy - Flex的原始英文版本翻译成中文，并在自闭症谱系障碍（ASD）儿童的家长中测试其心理测量特性。研究分为两个阶段：（1）从英文翻译成中文（Psy - Flex - C），随后对两个版本进行语义等效性评估、预测试，并与20位自闭症儿童家长就Psy - Flex - C的表面效度进行评估，与8位专家就Psy - Flex - C的内容效度进行评估。（2）对248位自闭症儿童家长进行横断面研究以进行效度验证，并随机选择50名参与者组成一个亚组，在2周的间隔时间内评估重测信度。Psy - Flex - C与原始版本显示出令人满意的语义等效性，并表现出足够的内部一致性（Cronbach's α = 0.84）和重测稳定性（加权kappa统计量 = 0.88）。Psy - Flex - C与接受与承诺疗法过程综合评估之间的中度相关性支持了同时效度（Pearson's r = 0.54，p < 0.01）。Psy - Flex - C显示，育儿压力高和低的家长之间的平均得分存在显著差异（t = 5.43，p < 0.001）。与原始量表类似，验证性因素分析显示Psy - Flex - C的最佳拟合单因素结构（X/df = 1.62，p = 0.13，RMSEA = 0.05，GFI = 0.99，CFI = 0.99，TLI = 0.98，SRMR = 0.023）。Psy - Flex - C可以作为一种可靠且有效的工具，用于ASD儿童家长自我报告心理灵活性。建议未来的研究使用来自不同文化和背景的多样化样本对Psy - Flex - C进行测试，以提高其普遍性。
