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.

推进心理灵活性的评估：慢性身体疾病患者的一种新的情境敏感测量方法的开发和验证

目前的研究旨在开发和验证一种新的情境敏感测量慢性疾病相关的心理灵活性：Psy-Flex-CI。本研究以286名葡萄牙成人为样本，探讨其因素结构和心理测量特性，这些成年人至少接受过一次慢性身体疾病的诊断。结果证实了Psy-Flex-CI单因素结构的合理性，具有很好的拟合指标。此外，研究结果支持Psy-Flex-CI的可靠性。在预期的方向上，psyf - flex - CI与其他感兴趣的测量（心理灵活性和不灵活性、身体功能欣赏、精神病理症状）之间也存在显著的相关性，支持收敛效度。此外，Psy-Flex-CI在心理灵活性的多维测量（MPFI-24）中显示出增量效度。综上所述，我们的研究结果表明，Psy-Flex-CI是一种可靠和有效的评估慢性身体疾病患者与慢性疾病相关的心理灵活性的方法。因此，Psy-Flex-CI的开发可能对慢性疾病领域的临床和研究做出有益的贡献。

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.
