چکیده
Objective: The present study was conducted to investigate the potential role of food craving and emotional processing in explaining and predicting the relationship between impulsivity and food addiction. Method: This study was descriptive and correlational research. The statistical population included all people with obesity who were referred to the health centers and nutrition clinics in Tehran in the spring and summer of 2023. In this research, 357 participants were selected through the convenience sampling method. Body mass index, the Barratt Impulsiveness Scale (Fossati et al., 2001), the Yale food addiction scale (Gerhard et al., 2009), the food craving questionnaire - trait (Sepda Benito et al., 2000), and the Emotional processing scale (Baker et al., 2007) were used to collect data. Data were analyzed using structural equation modeling through Amos24 software. Results: The results showed that the model fits appropriately with the observed data. The coefficient of the direct path of impulsivity and food addiction was positive and significant. The indirect relationship between impulsivity and food addiction through food craving and emotional processing was also positive and significant. This finding indicates that both emotional processing and food craving mediate the relationship between impulsivity and food addiction positively and meaningfully. Conclusion: It seems that emotional processing problems and impulsivity play a significant role in the etiology and continuation of pathological eating, and focusing on the interaction of these factors can be beneficial in the prevention and treatment of eating problems in overweight and obese people.

چکیده [English]
هدف: پژوهش حاضر با هدف بررسی نقش بالقوه ولع به غذا و پردازش هیجانی در تبیین و پیش‌بینی رابطه بین تکانشگری و اعتیاد به غذا انجام شد. روش: پژوهش حاضر بنیادی از نوع توصیفی و به روش همبستگی بود. جامعه آماری شامل کلیه افراد مبتلا به چاقی بود که در بهار و تابستان 1402 به مراکز بهداشتی درمانی و کلینیک‌های تغذیه تهران به مراجعه کردند. 148 نفر نمونه به‌روش نمونه‌گیری در دسترس انتخاب شدند. داده‌ها با استفاده از محاسبه شاخص توده بدنی شرکت‌کنندگان و مقیاس تکانشگری بارت (فوساتی و همکاران، 2001)، مقیاس اعتیاد به غذای یل (گرهارد و همکاران، 2009)، پرسشنامه ولع به غذا-صفت (سپدا بنیتو و همکاران، ۲۰۰۰) و مقیاس پردازش هیجانی (باکر و همکاران،2007) جمع‌آوری و با استفاد از مدل‌یابی معادلات ساختاری در نرم‌افزار Amos24 تحلیل شدند. یافته‌ها: نتایج نشان داد که مدل با داده‌های مشاهده‌شده برازش مطلوب دارد. ضریب مسیر مستقیم تکانشگری و اعتیاد به غذا مثبت و معنادار بود. رابطه غیرمستقیم بین تکانشگری و اعتیاد به غذا از طریق ولع به غذا و پردازش هیجانی نیز مثبت و معنادار بود. این یافته بیانگر آن است که هم پردازش هیجانی و هم ولع به غذا رابطه بین تکانشگری و اعتیاد به غذا را به صورت مثبت و معنادار میانجیگری می‌کند. نتیجه‌گیری: به نظر می‌رسد مشکلات پردازش هیجان و تکانشگری نقش معناداری در سبب‌شناسی و تداوم خوردن بیمارگون ایفا می‌کنند، و تمرکز بر تعامل این عوامل می‌تواند در پیشگیری و درمان مشکلات خوردن افراد دارای اضافه‌وزن و چاقی سودمند باشد.
