Paranoia is a key symptom in psychosis and associated with a range of poor outcomes. Earlier life experiences increase vulnerability to paranoid thinking, and attachment theory has been proposed as a key model in explaining this causal pathway. Previous reviews highlight evidence of associations between insecure attachment styles and overall severity of psychotic symptoms. Studies report on associations between insecure attachment and paranoia, but to date, this literature has not been adequately synthesized. The aim of the current review was to report the strength and consistency of associations between paranoia and insecure attachment across published studies, and provide systematic appraisal of study quality.

精神病患者不安全依恋与偏执狂之间的关系：系统文献综述。

妄想症是精神病的一个关键症状，与一系列不良结果有关。早年的生活经历增加了偏执思维的脆弱性，并且依恋理论已被提出作为解释这一因果途径的关键模型。以前的评论强调了不安全依恋风格与精神病症状的总体严重程度之间存在关联的证据。研究报告了不安全依恋和偏执狂之间的关联，但迄今为止，这些文献还没有得到充分的综合。本综述的目的是报告已发表研究中偏执狂和不安全依恋之间关联的强度和一致性，并提供对研究质量的系统评估。
