Introduction: Pennsylvania State Worry Questionnaire (PSWQ) is one of the most widely used measures for worry. The present study examined the psychometrics particularity of Farsi version of PSWQ for college students.
Method: No. of 424 students (248 girls and 176 boys) were selected by Convenience Sample method. No. of 424 students (248 girls and 176 boys) were selected by Convenience Sampling method. Measuring instruments were Pennsylvania State Worry Questionnaire, subscales anxiety state, trait anxiety and Beck Depression Inventory.
Results: Confirmatory factor analysis of the PSWQ revealed that a two-factor model (engagement of worry and absence of worry) is superior to a one-factor model in terms of fitness. The PSWQ demonstrated high internal consistency and Test Retest reliability (in a one- month time interval). In addition the significant correlation between PSWQ scores and the two variables of trait anxiety scores and depression scores indicated PSWQ's validity. In addition female scores were significantly higher than men.
Conclusion: Results of this study showed Farsi version of PSWQ has good psychometrics particularity in measuring student's worry.
