چکیده
وابستگی به تمرین فرایندی است که معمولأ بین ورزشکاران پرورش اندام بعد از رهاکردن تمرین، شخص را به تحمل علائم جسمانی و روانی وادار می‌کند.هدف پژوهش حاضر، تعیین روایی و پایایی نسخة فارسی مقیاس وابستگی به پرورش اندام بود. بدین‌منظور، 196 ورزشکار پرورش اندام زن و مرد به‌طور تصادفی خوشهای انتخاب شدند و نسخۀ فارسی مقیاس وابستگی به پرورش انداماسمیت و هال (2004) را تکمیل کردند. با استفاده از روش ترجمه- بازترجمه، درستی ترجمة نسخة فارسی مقیاس تأیید شد. سپس، برای تعیین روایی سازة پرسشنامه از تحلیل عاملتأییدی مبتنی بر مدل معادلات ساختاری و برای تعیین همسانی درونی از ضریب آلفای کرونباخ استفاده شد. نتایج تحلیل عامل تأییدی نشان داد که مدل اول (نُه سؤالی) برازش مطلوبی ندارد؛ اما بعد از حذف یک سؤال، مدل دوم با هشت سؤال از شاخصهای برازندگی (06/0 = شاخص ریشة میانگین مجذور برآورد تقریب، 91/0= شاخص برازش مقایسهای بنتلر؛ 86/0=شاخص برازش تاکر- لویس) و همسانی درونی قابل‌قبولی (همسانی درونی برای کل مقیاس 74/0 و برای خردهمقیاسهای وابستگی خبرگی، وابستگی تمرینی و وابستگی اجتماعیبه‌ترتیب 80/0، 70/0 و 73/0) برخوردار است؛ بنابراین، میتوان از نسخة فارسی تعدیل‌یافتة مقیاس وابستگی به پرورش اندام بهعنوان ابزاری روا و پایا برای ارزیابی و مطالعة وابستگی به پرورش اندام در ورزشکاران ایرانی بهره گرفت.

چکیده [English]
Exercise dependence, a process in which a person feels compelled to exercise and suffers physical and psychological symptoms when exercise is withdrawn, appears to be commonplace among bodybuilders. The purpose of this study was determining the validity and reliability of the Persian version of the bodybuilding dependence. In this regard 196 male and female bodybuilders selected by random cluster sampling and then completed the questionnaire. This scale at the first, with use of translation-back translation methods, face validity and translate accuracy of the Persian version of the questionnaire was confirmed. Then Confirmatory factor analysis (CFA) based on structural equations was used for validation of structure of the questionnaire, Cronbach alpha coefficient was used for validation of internal consistency of the questionnaire. The results for Confirmatory factor analysis showed that the first model bodybuilding dependence scale was not supported the favorable fit. But after eliminating the one question, the second model with 8 questions, had an acceptable fit index (Root Mean Square Error of Approximation=0.06, Comparative fit index=0.91, Tucker Lewis index=0.86) and internal consistency (Internal consistency for whole of scale 0.74 and subscales mastery dependence, training dependence and social dependence were equal to, 0.80, 0.70 and 0.73 respectively). Therefore, The Persian version of the modified bodybuilding dependence scale can be characterized as a valid and reliable tool to evaluate and study the bodybuilding dependence of Iranian athletes will benefit.
