Processes of psychological flexibility (PF) are positively associated with health and wellbeing in several chronic pain disorders. However, these processes have not been investigated in endometriosis, a chronic pain disorder affecting 5-10 % of women worldwide. This study is a preliminary investigation of the associations between PF or psychological inflexibility (PI) and daily functioning in people with a primary diagnosis of endometriosis.
This study is based on a secondary analysis of survey data from Swedish-speaking adult participants with chronic pain recruited online. The current study included only those reporting a diagnosis of endometriosis and significant long-term pain. All participants completed the Multidimensional Psychological Flexibility Inventory (MPFI), a measure of PF and PI, as well as other measures of PF, and measures of pain and daily functioning. Correlation and multiple regression analyses were performed to examine relations of PF and PI with measures of pain and daily functioning.
In general, PF facet scores from the MPFI did not correlate with pain interference but did correlate with depression, with the exception of acceptance. The overall facets of PI appeared to perform better as correlates and in regression. Established measures of PF performed in correlation and regression analyses generally as has been observed in other chronic pain populations, with significant positive associations.
In this preliminary analysis of PF and PI in participants with endometriosis-related pain, these processes appear relevant, especially in understanding depression, but results varied along with the measures used. Specifically, when employing the MPFI, the PI facets emerged as stronger correlates. The findings underscore the potential benefit of incorporating assessments of PF and PI as process variables in endometriosis-research, but also that careful consideration should be given when selecting instruments.
在几种慢性疼痛障碍中，心理灵活性（PF）的过程与健康和幸福感呈正相关。然而，这些过程在子宫内膜异位症中尚未得到研究，子宫内膜异位症是一种影响全球 5-10%女性的慢性疼痛障碍。本研究初步探讨了 PF 或心理不灵活性（PI）与原发性子宫内膜异位症患者日常功能之间的关联。
本研究基于对在线招募的慢性疼痛瑞典语成年参与者的调查数据的二次分析。本研究仅包括那些报告子宫内膜异位症和长期严重疼痛诊断的患者。所有参与者都完成了多维心理灵活性量表（MPFI），这是一种测量 PF 和 PI 的工具，以及其他 PF 测量工具和疼痛及日常功能测量工具。进行了相关分析和多元回归分析，以检验 PF 和 PI 与疼痛和日常功能测量指标的关系。
一般来说，MPFI 的 PF 方面得分与疼痛干扰无关，但与抑郁相关，除了接受方面。PI 的整体方面似乎作为相关性和回归更好地表现。PF 的既定测量工具在相关性和回归分析中的表现与在其他慢性疼痛人群中观察到的相似，存在显著的正相关。
在这项对与子宫内膜异位症相关疼痛的参与者的 PF 和 PI 的初步分析中，这些过程似乎是相关的，特别是在理解抑郁方面，但结果因所使用的测量工具而异。具体来说，当使用 MPFI 时，PI 方面表现出更强的相关性。这些发现强调了在子宫内膜异位症研究中纳入 PF 和 PI 作为过程变量的潜在益处，但在选择工具时也应谨慎考虑。
