People with chronic pain often struggle with their sense of self and this can adversely impact their functioning and well-being. Acceptance and Commitment Therapy particularly includes a process related to this struggle with self. A measure for this process, the Self Experiences Questionnaire (SEQ), was previously developed in people with chronic pain.
The aim of the current study was to validate a shorter version of the SEQ in people with chronic pain to reduce respondent burden and facilitate further research.
Data from 477 participants attending an interdisciplinary pain management programme were included. Participants completed measures of treatment processes (self-as-context, pain acceptance, cognitive fusion and committed action) and outcomes (pain, pain interference, work and social adjustment and depression) at baseline and post-treatment. Confirmatory factor analysis was used for item reduction. Correlations between scores from the shorter SEQ and other process and outcome variables were calculated to examine validity. Change scores of the shorter SEQ and their correlations with changes in outcome variables were examined for responsiveness.
An eight-item SEQ (SEQ-8) scale including two factors, namely Self-as-Distinction and Self-as-Observer, emerged, demonstrating good reliability (Cronbach's α = .87-.90) and validity (|r| = .14-.52). Scores from SEQ-8 significantly improved after the treatment (d = .15-21), and these improvements correlated with improvements in most outcomes.
The SEQ-8 appears to be a reliable and valid measure of self. This shorter format may facilitate intensive longitudinal investigation into sense of self and functioning and well-being.
慢性疼痛患者常常在自我认知方面存在困扰，这会对他们的功能和幸福感产生不利影响。接纳与承诺疗法特别包含了一个与这种自我挣扎相关的过程。之前针对慢性疼痛患者开发了一种衡量这个过程的工具——自我体验问卷（SEQ）。
本研究的目的是验证慢性疼痛患者中SEQ的一个较短版本，以减轻受访者负担并促进进一步研究。
纳入了477名参加跨学科疼痛管理项目的参与者的数据。参与者在基线和治疗后完成了治疗过程（自我即情境、疼痛接纳、认知融合和承诺行动）及结果（疼痛、疼痛干扰、工作和社会适应以及抑郁）的测量。使用验证性因素分析进行项目缩减。计算较短SEQ得分与其他过程及结果变量之间的相关性以检验效度。检查较短SEQ的变化得分及其与结果变量变化的相关性以评估反应性。
出现了一个包含两个因素（即自我区分和自我观察）的八项SEQ（SEQ - 8）量表，显示出良好的信度（克朗巴哈α系数 = 0.87 - 0.90）和效度（|r| = 0.14 - 0.
