ABSTRACT

Theoretical models and qualitative research suggest that dissociation can be functional in some circumstances, despite being a cause of concern for many. This is the first study that evaluates a novel questionnaire on positive appraisals of dissociation (the Positive Beliefs about Dissociation Questionnaire; PBD-Q), and its link with dissociation frequency and related distress. Development of items was based on lived experience expertise within the research team and qualitative findings. Items were refined through cognitive interviewing with people with lived experience of dissociation prior to deployment using an online survey. A sample of 228 participants scoring >10 on the Dissociative Experiences Scale (DES-II) completed a battery of measures comprising the PBD-Q and a previously developed measure of negative beliefs of dissociation. Exploratory factor analysis revealed three factors: positive beliefs about emotion management, positive beliefs about self-expression, and positive beliefs about maintaining social image. Within this particular sample the PBD-Q showed excellent internal consistency, face validity, convergent validity, and test–retest reliability. Higher scores on the PBD-Q were significantly related to higher frequencies of dissociative experiences as well as dissociation-related distress. The factor structure remained stable when the analyses were restricted to individuals scoring >30 on the DES-II. In conclusion, our findings indicate that positive beliefs about dissociation can be reliably and validly measured in adults who experience levels of dissociation that are higher than the general population. These beliefs could be involved in the maintenance of dissociation and represent promising targets for future research, clinical assessment, and treatment.

制定和初步评估有关分离经验的积极信念

摘要

理论模型和定性研究表明,解离可以在某些情况下发挥作用,尽管引起许多人的关注。这是第一项评估关于离解积极评价的新型问卷的研究(对离解问卷的积极信念; PBD-Q),它与离解频率和相关困扰有关。项目的开发基于研究团队中的实际经验和定性发现。在部署之前,使用在线调查通过与具有解离经验的人们进行认知访谈来对项目进行细化。228名参与者在“离婚经历量表”(DES-II)上得分大于10的样本完成了一系列测量,包括PBD-Q和先前开发的对离婚消极信念的测量。探索性因素分析揭示了三个因素:对情绪管理的积极信念,对自我表达的积极信念和对维持社会形象的积极信念。在此特定样品中,PBD-Q显示出极好的内部一致性,面部有效性,收敛性有效性和重测信度。PBD-Q上的较高分数与较高的解离经历频率以及与解离相关的苦恼显着相关。当分析仅限于在DES-II上得分> 30的个体时,因子结构保持稳定。总之,我们的研究结果表明,在经历了高于一般人群的解离水平的成年人中,对解离的积极信念可以得到可靠和有效的衡量。
