هدف از پژوهش حاضر، تعيين روايي و پايايي نسخة فارسي مقياس لذت فعاليت بدني در كودكان بود. بدين‌منظور 564 كودك از بازة سني 10 تا 12 سال به‌صورت تصادفي خوشهاي انتخاب شدند و نسخۀ فارسي مقياس لذت فعاليت بدني را تكميل كردند. روش اجرا بدين شكل بود كه ابتدا با استفاده از روش باز ترجمه، صحت ترجمة نسخة فارسي پرسش‌نامه تأييد شد و درادامه براي تعيين روايي سازة پرسش‌نامه از تحليل عامل تأييدي مبتني بر مدليابي معادلات ساختاري، براي تعيين همساني دروني از ضريب آلفاي كرونباخ و براي پايايي زماني سؤالات، از همبستگي درون طبقهاي در روش آزمون ـ آزمون مجدد استفاده شد. نتايج پژوهش نشان‌دهندة برازش مطلوب مدل نسخة فارسي مقياس لذت فعاليت بدني است. شاخصهاي برازندگي رمزي 05 /0، سي.اف.آي 92 /0 و ان.ان.اف.آي 9 /0 بود؛ همچنين، ضريب آلفاي كرونباخ با 83 /0 و ضريب همبستگي درون‌طبقه اي با 80 /0 از مقادير قابل‌قبولي برخوردار بودند. يافته ها همچنين از ساختار تك‌عاملي و 16 سؤالي مقياس اصلي حمايت ميكند. بنابراين، نسخه فارسي مقياس لذت فعاليت بدني از روايي سازه و پايايي دروني و زماني قابل‌قبولي در بين كودكان 10 تا 12 سال برخوردار است و ميتوان از آن به‌عنوان ابزاري روا و پايا براي ارزيابي لذت فعاليت بدني كودكان ايراني استفاده كرد.
