Morrison and colleagues have proposed that auditory hallucinations are the result of cognitive intrusions being misattributed to an external source due to such thoughts being inconsistent with the person's beliefs about his or her own mental processes (metacognitive beliefs). The aim of this study was to investigate the applicability of this model to psychotic symptoms of thought interference. Fifty psychotic patients with and without thought interference were compared on (i) frequency of cognitive intrusions, (ii) metacognitive beliefs, (iii) source monitoring and (iv) appraisals of an unrelated anomalous event (a card trick). As predicted, individuals with thought interference had an increased frequency of cognitive intrusions and of maladaptive metacognitive appraisals, lower perceived cognitive control, and were more likely to endorse appraisals regarding ‘permeability’ of the mind, on the card trick task, in comparison to individuals without thought interference. No significant differences were found on any measure when the patient group was divided into hallucinators and non-hallucinators, once other variables were controlled for. These findings suggest that Morrison's model may be more parsimonious for symptoms of thought interference than for auditory hallucinations.
