One hundred thirty two people were selected through convenience sampling, from the addicted clients who came to Torbat Heidarieh governmental or private clinics (treatment centers) in 1390. In order to gather data, meta cognitive behavior questionnaires (MCQ-30) and questionnaire to measure self-destructive behavior measures (Aghamohamadyan, 1388) were used. Data were analyzed using the SPSS software (version 16) to find out descriptive statistics, and Pearson correlation coefficient analysis.

Results: The most self-destructive behaviors of the participants were the use of permanent materials, fancy use of a variety of materials, and smoking. There was a significant negative correlation between Meta cognitive beliefs and self-destructive behaviors. Moreover, there was a significant relationship (p<0/01) between the overall score of self-destructive behaviors and the scores of people’s positive beliefs about worries, uncontrollability, danger, and cognitive confidence, need to control thoughts and cognitive self-consciousness.

Conclusion: Meta cognition plays an important role in the selection and persistence of incompatible coping mechanisms helping people improve their personal and social life.
