پژوهش حاضر با هدف بررسی ویژگی های روان‌سنجی نسخة فارسی پرسش‌نامة وابستگی به تمرین در ورزشکاران ایرانی انجام شد. تعداد ۲۳۰ ورزشکار نخبه از رشته‌های ورزشی انفرادی و تیمی به روش نمونه‌گیری دردسترس انتخاب شدند. ورزشکاران منتخب همگی از ورزشکاران حرفه‌ای بودند که پرسش‌نامة وابستگی به تمرین را تکمیل کردند. بر اساس نتایج حاصل از تحلیل عاملی اکتشافی، یک ساختار شش عاملی به دست آمد که 71/72 درصد از واریانس را تبیین می‌کند. نتایج تحلیل عاملی تأییدی نیز نشان داد ساختار شش عاملی وابستگی به تمرین (کناره‌گیری، تداوم، تحمل، عدم کنترل، زمان، اثر خواستن) از برازش خوبی برخوردار است. سنجش پایایی پرسش‌نامه با استفاده از روش‌های همسانی درونی (7/0) و روش دو نیم‌کردن گتمن (86/0) نشان داد این پرسش‌نامه از ضرایب پایایی مناسبی برخوردار است. بنابراین، این مطالعه نشان می‌دهد پرسش‌نامة وابستگی به تمرین بعد از حذف سه سؤال با داشتن ضرایب پایایی و روایی رضایت بخش، ابزاری مناسب برای سنجش وابستگی است که پژوهشگران قادر خواهند بود از پرسش‌نامة وابستگی به تمرین به عنوان ابزاری روا و پایا در سنجش وابستگی به تمرین استفاده کنند.
Psychometric Properties of Persian Version of Exercise Dependence Questionnaire in Athletes
چکیده [English]
This study investigated the psychometric properties of Persian version of exercise dependence scale in Iranian athletes. To do this, 230 athletes from group and individual sport were selected through accessible sampling method. Selected athletes were professional who accomplished exercise dependence scale. According to the result of experimental factor analysis, one structure with 6 factors components was found which encompass 72/71% of the total variability of the data. Result of Confirmatory factor analysis revealed six factor structures of exercise dependence (Withdrawal, Continuance, Tolerance, Lack of control, Time, Intention effect) has a good fit. The internal consistency (0/7) and (0/86) showed that exercise dependence questionnaire has suitable reliability coefficients. Therefore, the results of the present study showed that after deleting 3 items, the exercise dependence questionnaire has satisfactory reliability and validity which researchers are able to use exercise dependence questionnaire as a reliable and valid tool to measure exercise dependence.
