چکیده
هدف مطالعه، بررسی ویژگی‌های روانسنجی نسخه فارسی مقیاس یادگیری، اجرا و توجه عملکردی (LEAF) در ورزشکاران است. نمونه آماری شامل 252 (152 زن، 100 مرد) ورزشکار ایرانی بالای 17 سال بود که به روش گلوله برفی توسط ارسال پرسشنامه آنلاین وارد پژوهش شدند. ابزار پژوهش شامل مقیاس یادگیری، اجرا و توجه عملکردی- بزرگسالان کاستلانوس و همکاران (2018) و پرسشنامه نقص عملکردی بزرگسالان بارکلی (2011) بود که جهت تعیین روایی هم‌زمان استفاده شد. جهت بررسی روایی سازه الگوی تحلیل عاملی تأییدی مرتبه دوم مقیاس استفاده شد. نتایج نشان داد به‌طور کلی الگو از برازش مناسبی برخوردار است، به‌طوریکه کلیه حیطه‌ها (درک و یادگیری مفهومی، حافظه واقعی، توجه، سرعت پردازش، سازماندهی بصری، پردازش متوالی، حافظه فعال، حل مسئله جدید، ریاضی، خواندن، بیان مکتوب) دارای بار عاملی یا همبستگی بالایی با ابعاد اصلی خود بود (p≤0.001). پایایی‌ همسانی درونی با استفاده از آلفای کرونباخ در همه ابعاد بالاتر از 7/0 و مطلوب به‌دست آمد. همبستگی بین نمرات ابعاد و حیطه‌های مقیاس بین 33/0 تا 89/0 بود و روایی همگرای مناسبی را نشان داد. نتایج تحلیل تمایزات جهت بررسی روایی تشخیصی نشان داد نمره چهار به‌عنوان نقطه برش پرسشنامه مناسب می‌باشد. تحلیل واریانس چند متغیره نشان داد که ورزشکارن بر اساس سطح رقابت در کارکردهای اجرایی دارای تفاوت هستند که با افزایش سطح رقابت، وضعیت این کارکردها در ورزشکاران بهبود می‌یابد. با توجه به این که پرسشنامه LEAF روایی و پایایی مطلوبی را برای ورزشکاران بزرگسال ایرانی نشان داد، لذا پیشنهاد می‌گردد از این مقیاس در پژوهش‌های آتی در حیطه ورزشی استفاده گردد.

چکیده English

The aim of study was the psychometric of the Persian version of the Learning, Executive, and Attention Functioning (LEAF) scale in athletes. The statistical sample consisted of 252 (female=152) Iranian athletes older than 17 years who were selected using the snowball sampling method via sending an online questionnaire. The research tools, including the LEAF scale for adults (Castellanos et al., 2018) and the Barkley Functional Impairment Scale (2011), were used to examine the concurrent validity. The second order confirmatory factor analysis of the scale was used to examine the construct validity of the model. The obtained results showed that, the model has a good fit such that all domains (i.e., comprehension of conceptual learning, factual memory, attention, processing speed, visual organization, sequential processing, working memory, solving a novel problem, mathematics, reading, written expression) showed a high factor loading or correlation with their main dimensions (p≤0.001). Using Cronbach's alpha, the internal consistency reliability was obtained to be over 0.7 and desirable. The correlation between the scores of dimensions and the scale domains was 0.33-0.89, indicating an appropriate validity. The results of the differences analysis to examine the diagnostic validity showed the score of 4 as the cutoff point. MANOVA showed that athletes are significantly different in executive functions based on the level of competition and these functions improve in athletes by increasing the competition level. As the LEAF has appropriate reliability and validity coefficient among adult Iranian athletes, it is suggested that this scale be used in the future sport researches.
