There is a growing awareness of the relationship between trauma and psychosis. Studies have found associations between traumatic life experiences and the development of psychosis.
This study examined the prevalence of trauma exposure and post-traumatic stress disorder (PTSD) in 32 people with psychotic diagnoses and investigated associations between specific traumas and psychotic symptoms. The role of dissociation and cognitive factors was also explored.
The prevalence of lifetime trauma was high (94% of the sample reported at least one traumatic event). The prevalence of current PTSD was 53%. Severity of trauma was associated with severity of PTSD and psychotic experiences. Physical abuse was associated with positive psychotic symptoms and sexual abuse was specifically related to hallucinations. Dissociative processes and negative beliefs formed as a result of trauma were associated with psychotic experiences (particularly hallucinations).
These findings are consistent with the suggestion that psychosis may be trauma-induced, and other implications are considered.
人们越来越意识到创伤与精神病之间的关系。研究发现创伤性生活经历与精神病的发展之间存在关联。
本研究调查了32名患有精神病诊断的患者中创伤暴露和创伤后应激障碍（PTSD）的患病率，并研究了特定创伤与精神病症状之间的关联。还探讨了解离和认知因素的作用。
终生创伤的患病率很高（94%的样本报告至少经历过一次创伤事件）。当前PTSD的患病率为53%。创伤的严重程度与PTSD和精神病体验的严重程度相关。身体虐待与阳性精神病症状相关，性虐待与幻觉特别相关。创伤导致的解离过程和消极信念与精神病体验（特别是幻觉）相关。
这些发现与精神病可能由创伤引起的观点一致，并考虑了其他影响。
