ABSTRACT

Background

Delusions are a core feature of psychosis and are thought to exist on a continuum from healthy individuals to clinical populations. This study examined the relationship between delusion-like experiences, using the Peters Delusional Inventory (PDI), and two aspects of personal worldview: core schemas (positive and negative views of the self and others) and locus of control (LOC).

Methods

258 healthy participants without a history of psychiatric illness completed an online survey assessing these constructs. Stepwise regression controlling for age and negative affect, revealed that negative self-schemas significantly predicted the presence of delusion–like experiences whilst negative schemas of others significantly predicted both the presence of delusion–like experiences and associated levels of distress and preoccupation.

Results

Positive schemas did not relate to delusions as measured by the PDI. Hierarchical regression demonstrated that LOC did not significantly predict delusion–like experiences.

Discussion

The findings highlight that negative schemas of others may be more critically related to delusional experiences than negative self-schemas. Replication in clinical samples is required, while some implications for future research and clinical interventions in prodromal psychosis are examined.

妄想体验与非临床个体对自我和他人的负面看法有关

摘要

背景

妄想是精神病的核心特征，被认为存在于从健康个体到临床人群的连续统一体中。本研究使用彼得斯妄想量表 (PDI) 检验了类妄想体验与个人世界观的两个方面之间的关系：核心图式（对自我和他人的正面和负面看法）和控制点 (LOC)。

方法

258 名没有精神疾病史的健康参与者完成了一项评估这些结构的在线调查。控制年龄和消极情绪的逐步回归显示，消极的自我图式显着预测了妄想体验的存在，而其他人的消极图式显着预测了妄想体验的存在以及相关的痛苦和专注程度。

结果

PDI 衡量的积极模式与妄想无关。分层回归表明 LOC 并没有显着预测妄想样体验。

讨论

研究结果强调，与消极自我图式相比，他人的消极图式可能与妄想体验更密切相关。需要在临床样本中进行复制，同时检查对前驱精神病的未来研究和临床干预的一些影响。
