Abstract

Objective: The aim of the present study was to evaluate the factor structure as well as the validity and reliability of the Persian version of Perseverative Thinking Questionnaire (PTQ). Method: Data were collected in three samples. A student sample (N = 894) completed the Generalized Anxiety Disorder Scale (GAD-7), the Difficulties in Emotion Regulation Scale (DERS) and the PTQ. Participants from the general population (N = 252) filled out a battery of questionnaires including the Penn State Worry questionnaire (PSWQ), the Ruminative response scale (RRS), the Depression, Anxiety, Stress Scale-21 (DASS-21) and the PTQ. Finally, psychotic inpatients (N = 193) filled in the PTQ, only. Results: Confirmatory factor analysis indicated that the second-order model with three lower-order factors model showed adequate fit with the data in all three samples. In addition, the PTQ had good internal consistency and test-retest reliability. As to validity, the PTQ scores showed positive correlation with the PSWQ, RRS, DERS, GAD-7 and DASS-21. In addition, the PTQ was found to discriminate the clinical sample from student and general population samples. Conclusions: The findings provided preliminary support for validity and reliability of the scores derived from Persian version of the PTQ.
