Abstract

Trauma-related beliefs are theorized to contribute to the development and maintenance of psychosis symptoms. However, the evidence for this proposal has yet to be systematically reviewed. This article is the first to synthesize and meta-analyze studies examining associations between trauma-related beliefs and psychosis symptoms, including hallucinations, delusions, paranoia, and negative symptoms. A systematic database search of Medline, PsychINFO, Embase, Web of Science, CINHAL, and Cochrane identified a total of 15 articles that met the inclusion criteria for systematic review and 11 articles which met the inclusion criteria for meta-analysis. Separate random-effects meta-analyses were conducted for each psychosis symptom. Meta-analytic findings demonstrated a small to moderate association between trauma-related beliefs and hallucination severity (k = 7, r = 0.25, 95% CI 0.10-0.39), a moderate to large association with delusion severity (k = 8, r = 0.43, 95% CI 0.31-0.54), and large association with paranoia severity (k = 4, r = 0.58, 95% CI 0.49-0.66). Narrative synthesis findings indicate that evidence for an association between negative symptoms and trauma-related beliefs was inconclusive. The meta-analytic findings provide support for an association between trauma-related beliefs and positive psychosis symptoms. This provides evidence suggesting trauma therapies for psychosis that target these beliefs may improve distressing psychosis. However, further research adopting longitudinal designs and controlling for confounders is required to better establish causality, including mediation analysis of therapy trials.

创伤相关信念与精神病症状有关吗?系统回顾和荟萃分析。
从理论上讲,与创伤有关的信念有助于精神病症状的发展和维持。然而,这项建议的证据还有待系统地审查。本文首次综合并荟萃分析了创伤相关信念与精神病症状之间的关系,包括幻觉、妄想、偏执和阴性症状。通过对Medline、PsychINFO、Embase、Web of Science、CINHAL和Cochrane的系统数据库检索,共发现15篇文章符合系统评价的纳入标准,11篇文章符合元分析的纳入标准。对每种精神病症状进行单独的随机效应荟萃分析。荟萃分析结果显示,创伤相关信念与幻觉严重程度之间存在小到中度的关联(k = 7, r = 0.25, 95% CI 0.10-0.39),与妄想严重程度之间存在中到大的关联(k = 8, r = 0.43, 95% CI 0.31-0.54),与偏执严重程度之间存在大的关联(k = 4, r = 0.58, 95% CI 0.49-0.66)。叙述性综合研究结果表明,阴性症状与创伤相关信念之间存在关联的证据尚无定论。荟萃分析结果支持创伤相关信念与阳性精神病症状之间的关联。这提供了证据,表明针对这些信念的精神病创伤治疗可能会改善痛苦的精神病。然而,需要采用纵向设计和控制混杂因素的进一步研究来更好地建立因果关系,包括治疗试验的中介分析。
