Abstract

Background

A range of traumas have been linked to voices (auditory verbal hallucinations) and unusual perceptual experiences (UPEs) in other perceptual-sensory domains. Models of PTSD and positive symptoms of psychosis are insufficient in explaining the relationship between trauma and voices. The trauma-related voices (TRV) model was developed to generate novel research in this area.

Aims

This study aimed to investigate pathways from trauma to the frequency of UPEs based on a subset of hypothesised relationships in the TRV model.

Materials

The PTSD Diagnostic Scale for DSM-5, State Adult Attachment Measure, Depression Anxiety and Stress Scales-21, Perth Emotion and Regulation Competency Inventory, Dissociative Experiences Measure Oxford, and Multi-modality Unusual Perceptual Experiences Questionnaire.

Methods

We used path analysis in a non-clinical sample (N = 528) to model indirect effects from diverse trauma experiences to the frequency of multi-sensory UPEs via a subset of mediators within the TRV model: insecure attachment, emotion regulation deficits, negative affect and dissociation.

Results

Our model was an excellent fit to the data and accounted for 37.1% of variance in UPE frequency, and all direct (βs = .14–.61) and indirect pathways (βs = .01–.08) were significant (ps < .001).

Discussion

Our findings suggest that insecure attachment may link diverse trauma experiences to emotion regulation deficits and negative affect, which are linked to UPE frequency via dissociation.

Conclusion

Our findings provide preliminary evidence for a subset of relationships within the TRV model. Future studies are needed to gather stronger evidence of temporality and causation between these factors, and to test broader pathways within the TRV model.

从创伤到不寻常知觉体验的途径:不安全依恋、负面影响、情绪调节和分离的角色建模。

背景：一系列创伤与其他感知感官领域的声音（听觉-言语幻觉）和异常感知体验（UPE）有关。创伤后应激障碍和精神病阳性症状的模型不足以解释创伤和声音之间的关系。创伤相关声音（TRV）模型是为了在这一领域产生新的研究而开发的。目的：本研究旨在基于TRV模型中的一组假设关系，研究从创伤到UPE频率的途径。材料：创伤后应激障碍诊断量表DSM-5、状态成人依恋量表、抑郁焦虑和压力量表-21、珀斯情绪和调节能力量表、分离体验量表Oxford和多模态异常感知体验问卷 = 528），通过TRV模型中的一个子组介质对不同创伤经历对多感觉UPE频率的间接影响进行建模：不安全依恋、情绪调节缺陷、负面影响和分离。结果：我们的模型与数据非常吻合，占UPE频率方差的37.1% = .14-.61）和间接途径（βs = .01-.08）具有显著性（ps 讨论：我们的研究结果表明，不安全依恋可能将不同的创伤经历与情绪调节缺陷和负面影响联系起来，这通过分离与UPE频率有关。结论：我们的发现为TRV模型中的一个子集关系提供了初步证据。未来的研究需要收集更有力的证据来证明这些因素之间的时间性和因果关系，并在TRV模型中测试更广泛的途径。

期刊介绍： Psychology and Psychotherapy: Theory Research and Practice (formerly The British Journal of Medical Psychology) is an international scientific journal with a focus on the psychological and social processes that underlie the development and improvement of psychological problems and mental wellbeing, including: theoretical and research development in the understanding of cognitive and emotional factors in psychological problems; behaviour and relationships; vulnerability to, adjustment to, assessment of, and recovery (assisted or otherwise) from psychological distresses; psychological therapies with a focus on understanding the processes which affect outcomes where mental health is concerned.
