Cognitive styles and psychotic experiences in a community sample

Area of Science:

• Psychology
• Psychiatry
• Cognitive Science

Background:

• Paranoid delusions in clinical populations are linked to global, stable, and external attributions for negative events.
• Paranoia is prevalent in community samples, but its association with cognitive style is not well-established.

Purpose of the Study:

• To investigate the association between cognitive style and paranoia in a large community sample of young adults.

Main Methods:

• Utilized data from 2694 young adults in the ALSPAC cohort.
• Assessed psychotic experiences via semi-structured interview and cognitive style using the Cognitive Styles Questionnaire-Short Form (CSQ-SF).
• Employed logistic regression to analyze associations between paranoia and cognitive style domains, exploring the role of depressive symptoms.

Main Results:

• Paranoia was associated with overall CSQ-SF scores, and specifically with global and stable attributional domains.
• The association between paranoia and the global domain remained significant after adjusting for depressive symptoms.
• No significant association was found between paranoia and an external cognitive style.

Conclusions:

• Paranoid ideation in young adults is associated with a global cognitive style, rather than an external one.
• An external cognitive style might be indicative of more severe paranoid beliefs.
• Further research is needed to elucidate the role of depression in the paranoia-cognitive style relationship.
