چکیده

یکی از جنبه‌های تاریک فعالیت بدنی، وابستگی به تمرین است. این تحقیق با هدف رواسازی مقیاس وابستگی به تمرین-تجدید نظرشده انجام شد. جامعة آماری را شرکت‌کنندگان در فعالیت بدنی منظم در شهر کرمانشاه با هدف قهرمانی و ورزش همگانی تشکیل دادند. نمونه 307 نفر و در دسترس انتخاب شد که 155 نفر (%5/50) مرد و 152 نفر (%5/49) زن بودند. داده‌ها با 1) پرسشنامة مشخصات فردی و 2)مقیاس وابستگی به تمرین- تجدید نظرشدة سیمون‌داونس و همکاران (2004) جمع‌آوری شد. برای تجزیه و تحلیل آماری از محاسبة میانگین و انحراف استاندارد و برای آزمودن روایی سازه (عاملی)، از روش تحلیل عاملی تأییدی مبتنی بر مدل معادلات ساختاری استفاده شد. ضریب همبستگی پیرسون و آلفای کرونباخ به ترتیب برای محاسبة پایایی آزمون مجدد و همسانی درونی استفاده شد.
نتایج شاخص ریشة میانگین مجذور برآورد تقریب (RMSEA) 039/0 بود که زیر شاخص 05/0 می‌باشد. شاخص برازش مقایسه‌ای بنتلر (CFI) و شاخص برازش تاکر لویس یا غیرهنجاری بنتلر - بونت (TLI/NNFI) به ترتیب 95/0 و 93/0 بود. براساس نتایج، اندازة شاخص‌های برازندگی مدل اندازه‌گیری مرتبة دوّم مقیاس وابستگی به تمرین تجدید نظرشده، قابل قبول بود و از پرسشنامة اصلی 7-عاملی و 21-گویه‌ای حمایت کرد. ضریب همبستگی پیرسون، پایایی کل مقیاس را تأیید کرد (94/0) و آلفای کرونباخ برای کل مقیاس نیز 86/0 به دست آمد که این نتایج، روایی و پایایی نسخة فارسی مقیاس وابستگی به تمرین –تجدید نظر شده را تأیید کرد. از این پرسشنامه می‌توان برای اهداف آموزشی و پژوهشی استفاده کرد.

چکیده [English]

One of the dark aspects of physical activity is exercise dependence. The study performed to validate the "Exercise Dependence Scale-Revised". Population was participants in physical activities in Kermanshah city that exercised with two purposes: athletic and sport for all. Samples were 307 participants selected availably that 155 participants (50.5%) were male and 152 participants (49.5%) were women. Data were collected by demographic questionnaire and Symons Downs, Hausenblas, & Nigg's "Exercise Dependence Scale-Revised". For data analysis mean and SD calculated and for construct validity (factorial) examination confirmatory factor analysis based on structural equations model were used. Pearson correlation coefficient and Cronbach's alpha used for test-retest reliability and internal consistency calculation, respectively.
Finding of RMSEA was .039 that was under .05. CFI and TLI/NNFI measures were .95 and .93, respectively. According the results, goodness of fit measures of second-order of "Exercise Dependence Scale-Revised" was acceptable and supported 7-factor and 21-item structure of original questionnaire. Pearson correlation coefficient confirmed test-retest reliability of the scale (.94) and Cronbach's alpha for Scale was .96 that confirmed validity and reliability of the "Exercise Dependence Scale-Revised". The scale can be used with clinical, educational and research purposes.
