Abstract

The current study aimed to develop and validate a novel context-sensitive measure of chronic illness-related psychological flexibility: the Psy-Flex-CI. Its factor structure and psychometric properties were explored in a sample of 286 Portuguese adults who received at least one diagnosis of chronic physical illness. Results confirmed the plausibility of the single-factor structure of the Psy-Flex-CI, with very good fit indices. Also, findings supported the Psy-Flex-CI's reliability. Support for convergent validity was also found with significant correlations between the Psy-Flex- CI and other measures of interest (psychological flexibility and inflexibility, body functionality appreciation, psychopathological symptoms) in the expected directions. Additionally, the Psy-Flex-CI showed incremental validity over a multidimensional measure of psychological flexibility (MPFI-24). Overall, our findings suggest that the Psy-Flex-CI is a reliable and valid measure to assess chronic illness-related psychological flexibility in individuals diagnosed with chronic physical illness. The development of the Psy-Flex-CI may thus be a useful contribution for the chronic illness field, in both clinical and research contexts.

期刊介绍： The Journal of Contextual Behavioral Science is the official journal of the Association for Contextual Behavioral Science (ACBS). Contextual Behavioral Science is a systematic and pragmatic approach to the understanding of behavior, the solution of human problems, and the promotion of human growth and development. Contextual Behavioral Science uses functional principles and theories to analyze and modify action embedded in its historical and situational context. The goal is to predict and influence behavior, with precision, scope, and depth, across all behavioral domains and all levels of analysis, so as to help create a behavioral science that is more adequate to the challenge of the human condition.
