Introduction: The present study aimed to investigate the relationship between transdiagnostic factors and psychotic symptoms in individuals with schizophrenia disorder. 
 Materials and Methods: In this descriptive-correlational study, 60 individual with schizophrenia disorder in Mashhad and Neyshabur in 2017 were selected by convenience sampling method. The participants completed Positive and Negative Syndrome Scale (PANSS), Intolerance of Uncertainty Scale (IUS), Cognitive Avoidance Questionnaire (SAQ), Metacognition Questionnaire (MCQ), Acceptance and Action Questionnaire-II (AAQ-II) and Cognitive Emotion Regulation Questionnaire (CERQ). Data were analyzed by Pearson correlation and regression analysis. 
Results: The result showed that there are significant relationships between transdiagnostic factors, namely intolerance of uncertainty (P=0.01), cognitive avoidance (P=0.01), experiential avoidance (P=0.01), worry about worry (P=0.01), adaptive (P=0.01) and maladaptive (P=0.05) cognitive emotion regulation, and psychotic symptoms. In addition, experiential avoidance and intolerance of uncertainty predicted psychotic symptoms in individuals with schizophrenia disorder. 
Conclusion: The results of this study emphasize the importance of transdiagnostic factors in experience of psychotic symptoms in individuals with schizophrenia disorder.
