چکیده

مقیاس تفکر دوقطبی جهت ارزیابی وجود سبک‌شناختی نامنعطف سیاه یا سفید مورداستفاده قرار می‏گیرد. هدف از پژوهش حاضر، بررسی ویژگی‏های روان‌سنجی مقیاس تفکر دوقطبی در دانشجویان بوده است. بدین منظور، نمونه‏ای متشکل از ۴۱۷ نفر (۲۵۲ زن و ۱۶۵ مرد) از دانشجویان دانشگاه شیراز در سال تحصیلی ۱۴۰3-۱۴۰2 به روش نمونه‏گیری خوشه‏ای تصادفی انتخاب شدند و به نسخه فارسی مقیاس تفکر دوقطبی (اوشیو، 2009)، تحمل ابهام (مک‏لین، ۱۹۹۳‏) و پرسشنامه کمال‏گرایی مثبت و منفی (تری‏شورت، ۱۹۹۵) پاسخ دادند. جهت بررسی روایی مقیاس از تحلیل عاملی اکتشافی و تأییدی و روایی ملاکی و برای تعیین پایایی پرسشنامه از روش همسانی درونی (آلفای کرونباخ) استفاده شد. نتایج تحلیل عاملی اکتشافی نشان داد که مقیاس تفکر دوقطبی از سه عامل ترجیح تفکر دوقطبی،‏ باورهای دوقطبی و تفکر سود و زیان تشکیل شده است. نتایج تحلیل عامل تأییدی نیز برازش مدل سه عاملی را تأیید نمود. به‌علاوه، روایی ملاکی مقیاس تفکر دوقطبی با مقیاس‏های تحمل ابهام و کمال‏گرایی نیز مطلوب بود. همچنین، مقادیر ضرایب آلفای کرونباخ در دامنه بین ۷۰/۰‏ تا ۸۵/۰ ‏به دست آمد و نشان داد که مقیاس از پایایی مطلوبی برخوردار است. به‌طورکلی یافته‏ها حاکی از مناسب بودن ویژگی‏های روان‌سنجی پرسشنامة تفکر دوقطبی بود و می‏توان از این ابزار برای کاربردهای تحقیقاتی و بالینی استفاده کرد.

چکیده [English]

The Dichotomous Thinking Scale (DTS) can be used to assess the presence of a rigid, “black and white” cognitive thinking style. This study aimed to examine the psychometric properties of dichotomous thinking scale in students. For this purpose, a sample consisting of 417 students (252 female and 165 male) of Shiraz University in the academic year 2023-2024 was selected by random cluster sampling and responded to the Persian version of Dichotomous Thinking (Oshio, 2009), Ambiguity Tolerance (Mc Lain, 1993) and Positive/Negative Perfectionism (Terry-short, 1995) Scales. Finally, based on data collected, exploratory and confirmatory factor analysis and criterion validity were employed to determine the construct validity and the reliability of the questionnaire was assessed via internal consistency. The results of exploratory factor analysis showed that the dichotomous thinking scale consists of three factors: preference for dichotomy, dichotomous belief and profit-and-loss thinking. The confirmatory factor analysis related to three-factor model represented an acceptable fit. Moreover, the criterion validity of the dichotomous thinking scale with Ambiguity Tolerance and perfectionism scales were adequate. Also, Internal consistency (Cronbach’s alpha) was calculated 0/70 – 0/85 and indicated appropriate reliability of the DTS. In conclusion, the Persian version of the Dichotomous Thinking Scale possesses acceptable psychometric properties and is a reliable, valid, and concise measure for psychological research and clinical Trails.
