چکیده:
Objectives: New cognitive theories of delusions have proposed that deficit or bias in inference
stage (a stage of normal belief formation) is significant in delusion formation. The aim of this
study was predicting the severity of delusions based on jumping-to-conclusion bias in patients
with schizophrenia.
Methods: The sample consisted of 60 deluded patients with schizophrenia who were selected
from the Ebnesina and Razi hospitals in Shiraz using convenience sampling method. The
Similarity 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 part
of the variance of delusions.
Discussion: These results generally indicated that the jumping to conclusion biases may
provide a more useful explanation for the delusion formation.

Prediction of severity of delusion based on jumping-to-conclusion bias in Schizophrenia patients.
The aim of this study was predicting the severity of delusions based on jumping-to-conclusion bias in patients with schizophrenia.
The beads task is a computerized tool for measuring the jumping-to-conclusion bias in schizophrenia patients with delusion.
Moreover, several other research have used this task to investigate the jump- ing-to-conclusion bias in schizophrenia patients with de- lusion but have not confirmed the bias yet [13-15].
Task ambiguity in the instruction results in the subjects not realizing the intentions of the examiner and instead utilizing their own interpretation of the task to complete it [11] because of the fact that the examiner offers just a set of beads to the participants, they do not have any opportunities to correct their mistakes; hence, their scores are not a great index for jumping to conclusion bias [12].
Therefore, a major goal of this research is to predict the severity of delusion based on jumping-to-conclusion bias in schizophrenia patients with respect to the similarity task.
The participants, with schizophrenia disorders who had experienced delusion with different severity, were asked to perform a similarity task.
Correlations among the jumping- to-conclusion bias and severity of delusion are shown in Table 1.
Some studies have shown that schizophrenia patients with delusion have jumping-to-conclusion bias and this out- come repeats in this research again.
