Flexibility is a key component of executive function, and is related to everyday functioning and adult outcomes. However, existing informant reports do not densely sample cognitive aspects of flexibility; the Flexibility Scale (FS) was developed to address this gap. This study investigates the validity of the FS in 221 youth with ASD and 57 typically developing children. Exploratory factor analysis indicates a five-factor scale: Routines/rituals, transitions/change, special interests, social flexibility, and generativity. The FS demonstrated convergent and divergent validity with comparative domains of function in other measures, save for the Generativity factor. The FS discriminated participants with ASD and controls. Thus, this study suggests the FS may be a viable, comprehensive measure of flexibility in everyday settings.
灵活性是执行功能的关键组成部分，且与日常功能及成人期结局相关。然而，现有的知情者报告并未密集抽样灵活性的认知方面；灵活性量表（FS）正是为填补这一空白而开发。本研究调查了FS在221名患有自闭症谱系障碍（ASD）的青少年和57名发育正常儿童中的有效性。探索性因素分析表明该量表包含五个因素：日常活动/仪式、转换/变化、特殊兴趣、社交灵活性和创造力。除创造力因素外，FS在其他测量中的功能比较领域显示出收敛效度和区分效度。FS能够区分患有ASD的参与者和对照组。因此，本研究表明FS可能是日常环境中灵活性的一种可行、全面的测量方法。
