The Relationships Between Multidimensional Schizotypy and Metacognitive Beliefs

There has been a recent surge in schizotypy and metacognition research. Metacognition is an umbrella term for higher-order thought processes. Here, we focussed on maladaptive metacognitive beliefs, which are beliefs related to one's thought processes and often play an important role in the preponderance of psychological disorders. Despite the extensive literature, relatively less is known about metacognitive beliefs in the context of multidimensional schizotypy, which consists of positive, negative, and disorganised dimensions and represents the milder forms of schizophrenia symptoms and vulnerability to developing schizophrenia. This is the first study that examined the links not only with positive schizotypy, but also with negative and disorganised schizotypy. We also attempted to circumvent the limitations related to schizotypy assessment in the previous studies by using a newly developed measure, the Multidimensional Schizotypy Scale (MSS), which was based on the current operationalisations of the construct. We examined the links in a non-clinical sample, including first-year psychology students and members of the wider community of an Australian university (N = 68). Self-report data was collected by administering the Metacognitions Questionnaire-30, MSS, and Marlowe-Crowne Social Desirability Scale to control the self-report measures' social desirability biases. Results revealed positive correlations of maladaptive metacognitive beliefs not only with positive schizotypy, but also with negative and disorganised schizotypy. Our findings support the importance of examining schizotypy as a multidimensional construct. Further, our findings have implications for research and practice, including treatment modalities focusing on the modification of metacognitive beliefs for the prevention of schizophrenia and related conditions.
