چکیده

مقدمه: پژوهش حاضر باهدف بررسی ویژگی‌های روان‌سنجی (روایی و پایایی) مقیاس نیاز به شناخت در میان دانش­آموزان پایه سوم دبیرستان انجام شد. روش: برای این منظور 392 نفر (168 پسر و 224 دختر) از دانش ­آموزان پایه سوم دبیرستان‌های شهر شیراز به روش نمونه‌گیری خوشه‌ای چندمرحله‌ای انتخاب و به پرسشنامه خود گزارشی نیاز به شناخت (NCS) کاچیوپو و همکاران پاسخ دادند. برای بررسی روایی سازه این مقیاس از روش تحلیل عاملی تأییدی و همسانی درونی و برای بررسی پایایی مقیاس ضریب آلفای کرونباخ مورد استفاده قرار گرفت. یافته‌ها: به‌طور کلی مشخصه‌های برازندگی مدل تحلیل عاملی تأییدی حاکی از برازش مناسب داده‌های پژوهش با ساختار عاملی مقیاس نیاز به شناخت می‌باشد. همچنین روش همسانی درونی نیز بیانگر روایی سازه این مقیاس است. ضریب آلفای کرونباخ به دست آمده نیز بیانگر ثبات اندازه‌گیری مقیاس نیاز به شناخت می‌باشد. نتیجه‌گیری: بر مبنای این نتایج می‌توان مقیاس نیاز به شناخت کاچیوپو و همکاران را به‌عنوان یک ابزار اندازه‌گیری مناسب در پژوهش‌های مربوط به دانش آموزان دبیرستانی مورد استفاده قرار داد.

چکیده [English]

Aims: This study aimed to examine the psychometric features (validity and reliability) of the short form of Need for Cognition Scale (NFS) in high school students. Method: For this purpose, 392 students (168 male and 224 female) of Shiraz high schools were selected by multistage cluster sampling method. They responded to the self-report need for cognition scale developed by Cacciopo et al. To assess the construct validity of this scale, confirmatory factor analysis and internal consistency were used. Moreover, Cronbach's alpha coefficient was used to evaluate the reliability of the scale. Results: Generally, the goodness of fit characteristics of the confirmatory factor analysis model indicated a good fit of the data with factor structure of the need for cognition scale. Also, internal consistency method indicated the construct validity of the scale and the Cronbach's alpha coefficient indicated the stability of the measurement of the scale. Conclusion:  Based on these results, one can use the need for cognition scale developed by Cacciopo et al. as an acceptable measurement tool to study high school students.
