The aim of the present study was to examine psychometric properties of the Schema Questionnaire, including reliability and validity in a sample of university students (n=387). The original version of the Schema Questionnaire was made for measuring the early maladaptive schemas by Young adults. It is assumed that early maladaptive schemas may lead to psychological disorders. The factor analysis of 205 item of the schema Questionnaire confirmed the Young's offered schemas. The Short Form of Schema Questionnaire (SQ-SF) is made for measuring of 15 early maladaptive schemas based on original version (Young, 1998). Factor analysis with principle component method extracted 11 factors in this study. Results of SCL-25 Questionnaire showed that the Schema Questionnaire-Short Form (SQ-SF) has enough construct validity for students of university population. .
