Description
Summary:Objectives: New cognitive theories of delusions have proposed that deficit or bias in inferencestage (a stage of normal belief formation) is significant in delusion formation. The aim of thisstudy was predicting the severity of delusions based on jumping-to-conclusion bias in patientswith schizophrenia. Methods: The sample consisted of 60 deluded patients with schizophrenia who were selectedfrom the Ebnesina and Razi hospitals in Shiraz using convenience sampling method. TheSimilarity Task was used to measure the jumping-to-conclusion biases. Results: Its results have shown that the jumping-to-conclusion biases could predict a great partof the variance of delusions. Discussion: These results generally indicated that the jumping to conclusion biases mayprovide a more useful explanation for the delusion formation.
