چکیده

مقدمه: افکار تکرارشونده منفی یکی از مهم­ترین عوامل فراتشخیصی مشترک در شکل­گیری و تداوم اختلال­های هیجانی است. هدف پژوهش حاضر بررسی ویژگی­های روانسنجی نسخه 10 سؤالی پرسشنامه افکار تکرارشونده  بود.
روش: در یک پژوهش مقطعی- توصیفی، 651 دانشجو از دانشگاه­های تهران به روش نمونه­گیری خوشه­ای چندمرحله­ای انتخاب و به پرسشنامه افکار تکرارشونده، پرسشنامه افسردگی بک-ویرایش دوم، پرسشنامه اضطراب بک، مقیاس­ عاطفه مثبت و منفی، پرسشنامه نگرانی ایالت پنسیلوانیا و مقیاس سبک پاسخ‌دهی نشخواری پاسخ دادند. به‌منظور تعیین اعتبار سازه از روش تحلیلی عاملی اکتشافی، برای تعیین همسانی درونی از ضرایب آلفای کرونباخ و برای ارزیابی اعتبار همگرا و واگرا، از ضریب همبستگی نسخه 10 سؤالی پرسشنامه افکار تکرارشونده با مقیاس­های سنجش اضطراب، افسردگی، نشخوار فکری، نگرانی، عاطفه منفی و مثبت استفاده شد.
یافته­ها: نتایج پژوهش نشان داد نسخه 10 سؤالی پرسشنامه افکار تکرارشونده از ساختار تک عاملی، پایایی بازآزمایی مطلوب (76/0) و همسانی درونی بالایی (91/0) برخوردار بود. همچنین نتایج نشان داد که این ابزار با افسردگی، اضطراب، عاطفه منفی، نشخوار فکری و نگرانی اعتبار همگرای و با عاطفه مثبت اعتبار واگرای مطلوبی داشت.
نتیجه­گیری: در مجموع، نتایج پژوهش حاضر شواهدی دال بر اعتبار و پایایی مطلوب نسخه 10 سؤالی پرسشنامه افکار تکرارشونده، به‌عنوان ابزار بررسی مهم­ترین عامل فراتشخیصی یعنی افکار منفی تکرارشونده در بین دانشجویان ایرانی فراهم آورد.

چکیده [English]

Introduction:Repetitive negative thinking (RNT) is one of the most important common transdiagnostic factors in the development and maintenance of emotional disorders. Aim of this study was to investigate the psychometric properties of Repetitive Thinking Questionnaire-10 items (RTQ-10(.
Method:In this cross-sectional study, 651 students of Tehran Universities was selected by multistage cluster sampling  method and completed Repetitive Thinking Questionnaire, Beck DepressionInventory-II, Beck Anxiety Inventory, Positive and Negative Affect Schedule(PANAS),The Penn State Worry Questionnaire (PSWQ)  and Ruminative Response Scale. Theconstruct validity was used to determineexploratory factor analysis,Cronbach’s alpha coefficients was performed  to determine the internal consistency and correlation coefficient of Repetitive Thinking Questionnaire-10 items (RTQ-10) with scales of measuring anxiety, depression, rumination, worry, positive and negative affect was usedto assess convergent and divergent validity.
Results: The results showed of Repetitive Thinking Questionnaire-10 items (RTQ-10) has single-factor structure with  good test-retest reliability (0.76) and high internal consistency (0.91). The results also showed that this questionnaire has favorable convergent validity with depression, anxiety, negative affect, rumination and worry along with divergent validity with positive affect.
Conclusion: Overall, the results provide evidence based on favorable reliability and validity of  Repetitive Thinking Questionnaire-10 items (RTQ-10) as major tool for assessment of transdiagnostic factor namely negative repetitive negative thinking among Iranian students.
