The relationship between self-concept and paranoia in the general population

Abstract

Background: Paranoia is prevalent in children, adolescents, and young adults. We require greater understanding of the factors that are related to paranoia. Chapter one includes a systematic review and meta-analysis to explore the relationship between paranoia and selfconcept in children and adolescents. Chapter two includes an empirical study that tested a moderation model, to explore whether the relationship between negative-self and -other beliefs and paranoia is moderated by psychological flexibility.
Method: The review was preregistered on PROSPRO, CRD42023380191 and PRISMA guidelines were followed to review the articles. For the empirical study a longitudinal design was used, involving participants (n=127) completing questionnaires at two time points: Time 1 (T1; baseline) and Time 2 (T2; 4 weeks later).
Results: Nine papers (overall 5,538 participants) were included in the review. The metaanalysis found a significant positive relationship, with a medium effect size, between negative self-concept (including positive self-concept reversed) and paranoia (r = 0.41,
