Due to the lack of a Persian version of the present instrument, the present study examined the psychometric properties and functional structure of the Young Positive Schema Questionnaire in female students of the Islamic Azad University of Varamin.

In order to evaluate the internal reliability of the questionnaire, Cronbach's alpha method was used and in order to evaluate the time reliability of the retest method, divergent validity of Pearson correlation with SPSS software was used. Confirmatory factor analysis with LISREL software was used to evaluate the construct validity.

The results showed that the 76-item model with 17 factors was approved. Pearson correlation coefficient between the scores obtained from the two performances ranged from 0.68 to 0.87 and all were significant (P<0.001) which indicates a high correlation between the two tests and as a result the reliability of the appropriate retest of all subscales of the Young positive schema questionnaire.
