IntroductionIn a context in which psychological flexibility has been revealed to be a pivotal process in psychological well-being, the Psy-Flex scale has emerged as a theoretically based, context-sensitive, brief scale that can be used in different settings and has good psychometric properties.MethodsThis study aims at analyzing the psychometric properties of the Spanish translation of the Psy-Flex, based on the responses of a sample of 170 healthy individuals. Standard psychometric methods and network analysis were used to evaluate the behavior of the adapted scale.ResultsThe analyses on the six items of the Spanish Psy-Flex yielded a single-factor structure (χ2 = 20.435, df = 8, p = 0.009; χ2/df = 2.554; GFI = 0.961; NFI = 0.952; TLI = 0.943; CFI = 0.970: SRMR = 0.046: RMSEA = 0.096, RMSEA 90% CI = 0.045, 0.148, PCLOSE = 0.065), good internal consistency (Cronbach’s α = 0.839; 95% CI = 0.812, 0.866), and high consistency across time points (ICC = 0.887; 95% CI = 0.852, 0.916). The scale scores were associated with a wide range of measures related to psychological flexibility and inflexibility, well-being and mental health. Network analysis further supported the idea that the Psy-Flex items form a coherent structure.DiscussionThe Spanish version of the Psy-Flex is a psychometrically adequate scale for use in a population without mental health problems as a measure of psychological flexibility.
