Dissociative and metacognitive factors in hallucination-proneness when controlling for comorbid symptoms.
Summary of "Dissociative and metacognitive factors in hallucination-proneness when controlling for comorbid symptoms."
Introduction. Recent studies have linked hallucination-proneness to dysfunctional metacognitive beliefs, dissociation, and disrupted capacity to discriminate between internal and external cognitive events (reality discrimination). This study addressed a number of methodological limitations of previous research by investigating the relationship between hallucination-proneness and the aforementioned variables while controlling for comorbid symptoms. Method. A large sample of nonclinical participants was screened on measures of hallucination-proneness, cognitive intrusions, paranoid ideation, metacognitive beliefs, and dispositional mindfulness (including measures of dissociation-like experiences). In addition, a signal detection task was used to investigate reality discrimination in four subgroups of participants selected on the basis of their scores on hallucination-proneness and intrusions. Results. Regression analyses for the self-report data were conducted to investigate the predictors of hallucination-proneness and paranoia when controlling for comorbid symptoms. Also, between-group differences on the behavioural data were tested to determine whether perturbed reality discrimination is specifically associated with hallucination-proneness rather than cognitive intrusions. Results revealed that metacognitive beliefs are more strongly associated with intrusions and paranoia than hallucination-proneness, whereas hallucination-proneness is related to perturbed reality discrimination and dissociation. Conclusions. These results clarify previous research on metacognitive dysfunction in hallucination-proneness, and highlight the importance of controlling for the covariation among symptoms when investigating the cognitive processes underlying psychotic experiences.

A family of transcription factors that contain a single cut domain and a divergent homeodomain. They regulate gene networks by controlling the expression of other transcription factors and they play an important role in CELL DIFFERENTIATION and METABOLISM.
Peptide initiation factors from eukaryotic organisms. Over twelve factors are involved in PEPTIDE CHAIN INITIATION, TRANSLATIONAL in eukaryotic cells. Many of these factors play a role in controlling the rate of MRNA TRANSLATION.
Plasmids controlling the synthesis of hemolysin by bacteria.
A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
The relating of causes to the effects they produce. Causes are termed necessary when they must always precede an effect and sufficient when they initiate or produce an effect. Any of several factors may be associated with the potential disease causation or outcome, including predisposing factors, enabling factors, precipitating factors, reinforcing factors, and risk factors.
