چکیده

مقدمه: اتخاذ یک رژیم غذایی متعادل بر ارتقای سلامت انسان تأثیرگذار است. بااین‌حال، تمرکز مفرط روی سلامتِ خوردن ممکن است منجر به وسواس غذایی شود که به‌عنوان ارتورکسیای عصبی توصیف می‌گردد. پژوهش حاضر با هدف تعیین ویژگی­های روان­سنجی نسخه­ی فارسی مقیاس ارتورکسیای عصبی (ONS) انجام شد. روش: جامعه­ی آماری این پژوهش را کلیه­ی دانشجویان کارشناسی دانشگاه آزاد اسلامی واحد علوم و تحقیقات تهران در سال تحصیلی 99-98 تشکیل دادند که از بین آن‌ها تعداد 322 دانشجو (201 زن، 121 مرد) به روش نمونه‌گیری چندمرحله‌ای انتخاب شدند و به پرسشنامه­های ارتورکسیای عصبی (ONS)، نگرش خوردن (EAT-26)، وسواس فکری - عملی (OCI-R)، کمال­گرایی (MPS)، انعطاف­پذیری ذهنی تصویر بدن (BI-AAQ) و پنج عاملی شخصیت (NEO-FFI) پاسخ دادند. داده‌های جمع­آوری شده با استفاده از روش تحلیل عاملی اکتشافی، تحلیل عاملی تأییدی، آلفای کرونباخ و ضریب همبستگی پیرسون در نرم­افزارهای SPSS و AMOS تحلیل شد. یافته‌ها: ﻧﺘﺎﯾﺞ ﺗﺤﻠﯿﻞ ﻋﺎﻣلی اﮐﺘﺸﺎﻓﯽ، 2 ﻋﺎﻣﻞ ﺑﺎ ﻣﻘﺎدﯾﺮ وﯾﮋه­ی ﺑﯿﺸﺘﺮ از ﯾﮏ را آﺷﮑﺎر ﮐﺮد که 92/41 درصد از واریانس را تبیین کردند. شاخص­های تحلیل عاملی تأییدی نیز دلالت بر برازش مطلوب مدل 2 عاملی این مقیاس داشت. پایایی کُل مقیاس با استفاده از ضریب آلفای کرونباخ و دو نیمه کردن به ترتیب 78/0 و 81/0 بدست آمد. روایی همگرا و واگرا نیز از طریق محاسبه‌ی همبستگی مقیاس با پرسشنامه­های مذکور تأیید شد (05/0>p). همچنین، این مقیاس همبستگی مثبت و معناداری با روان‌رنجورخویی داشت (01/0>p). نتیجه‌گیری: مقیاس ارتورکسیای عصبی از روایی و پایایی نسبتاً خوبی جهت استفاده در نمونه­های ایرانی برخوردار است و می­تواند ابزاری مناسب جهت استفاده در پژوهش­های این حوزه باشد.

چکیده [English]

Objective: Adopting a balanced diet promotes human health. However, excessive focus on healthy eating can lead to food obsession, which is termed orthorexia nervosa (ON). The aim of this study was to determine the psychometric properties of the Persian version of the Orthorexia Nervosa Scale (ONS). Method: The statistical population of this study consisted of all undergraduate students of the Islamic Azad University, Tehran Science and Research Branch in the academic year 98-99, among whom 322 students (201 females, 121 males) were selected by multistage sampling, and they responded to the Orthorexia Nervosa Scale (ONS), the Eating Attitude Test (EAT-26), the Obsessive-Compulsive Inventory (OCI-R), the Multidimensional Perfectionism Scale (MPS), the Body    Image-Acceptance and Action Questionnaire (BI-AAQ), and the NEO Five Factor Inventory (NEO-FFI). The data were analyzed by exploratory factor analysis, confirmatory factor analysis, Cronbach’s alpha and Pearson correlation using SPSS and AMOS. Findings: Results of the exploratory factor analysis showed 2 factors with eigenvalues higher than 1 which explained 41/92% of the total variance. Also, confirmatory factor analysis indicators implied the optimal fitness of  two-factor model of this scale. The total reliability of the scale was estimated to be respectively 0.78 and 0.81 using Cronbach’s alpha and split half. Convergent validity and divergent validity were also confirmed by calculating scale correlation through the aforementioned scales (p<0.05). Also, this scale had a positive and significant correlation with neuroticism (p<0.01). Conclusion: The Orthorexia Nervosa Scale has a relatively proper validity and reliability for being used in Iranian samples and can be a suitable tool for researches of this field.
