背景认知模型表明，与幻听相关的痛苦最好通过对声音的信念来理解。不太清楚的是，是什么因素支配着这种信念。本研究旨在探讨创伤性生活事件对声音和任何相关痛苦的信念的影响。创伤性生活事件和相关的心理后遗症的性质和患病率的差异进行了比较，在两组的声音听者：精神病的声音听者主要是负面的信念的声音（PVH）和非精神病的声音听者主要是积极的信念的声音（NPVH）。然后将两组的数据结合起来，以检查哪些因素可以显着解释对声音的信念的差异，从而影响痛苦的程度。两组都报告了创伤性生活事件的高患病率，尽管更多的PVH报告了足以诊断为创伤后应激障碍（PTSD）的创伤症状。此外，更多的PVH报告说，他们在童年时遭受过性虐待。目前的创伤症状（重新体验，回避和过度觉醒）被认为是一个重要的预测信念的声音。创伤变量在焦虑和抑郁的方差中占显著比例。研究结果表明，关于声音的信念可能至少部分地在创伤性生活事件的背景下被理解。
Background. Cognitive models suggest that distress associated with auditory hallucinations is best understood in terms of beliefs about voices. What is less clear is what factors govern such beliefs. This study aimed to explore the way in which traumatic life events contribute towards beliefs about voices and any associated distress.Method. The difference in the nature and prevalence of traumatic life events and associated psychological sequelae was compared in two groups of voice hearers: psychiatric voice hearers with predominantly negative beliefs about voices (PVH) and non-psychiatric voice hearers with predominantly positive beliefs about voices (NPVH). The data from the two groups were then combined in order to examine which factors could significantly account for the variance in beliefs about voices and therefore levels of distress.Results. Both groups reported a high prevalence of traumatic life events although significantly more PVH reported trauma symptoms sufficient for a diagnosis of post-traumatic stress disorder (PTSD). Furthermore, significantly more PVH reported experiencing childhood sexual abuse. Current trauma symptoms (re-experiencing, avoidance and hyperarousal) were found to be a significant predictor of beliefs about voices. Trauma variables accounted for a significant proportion of the variance in anxiety and depression.Conclusions. The results suggest that beliefs about voices may be at least partially understood in the context of traumatic life events.
