پايايي و روايي نسخه فارسي آزمون مقياس سنجش فعاليت‌ها (ASK) در كودكان فلج مغزي

Validity and reliability of activities scale for kids (ASK) in children with cerebral palsy

مقدمه: هدف از پژوهش حاضر فارسي‌سازي ابزار سنجش فعاليت‌هاي روزمره زندگي در كودكان از طريق ترجمه آزمون "مقياس سنجش فعاليت‌ها در كودكان" و بررسي روايي و پايايي نسخه فارسي شده در گروه هدف بود. مواد و روش‌ها: تحقيق حاضر يك مطالعه متدلوژيك است كه در آن طي 5 مرحله پرسش‌نامه Activities scale for kids (ASK) به زبان فارسي ترجمه و روايي و پايايي آن بررسي شد. كودكان فلج مغزي از جامعه در دسترس مراجعه كننده به كلينيك‌هاي كاردرماني دانشگاه علوم بهزيستي و توان‌بخشي و كودكان سالم به روش گلوله برفي نمونه‌گيري شدند. داده‌هاي به دست ‌آمده از اطلاعات 73 كودك فلج مغزي و 69 كودك سالم در محدوده سني 5 تا 15 سال با استفاده از نرم‌افزار 13SPSS مورد تجزيه و تحليل قرار گرفتند و پايايي (تكرار پذيري به فاصله 2 هفته و پايايي دروني) و روايي (محتوا بر اساس روش Lawasche، همزمان با آزمون Gross motor function classification system-expanded revised يا GMFCS-E and R و افتراقي) پرسش‌نامه ASK بررسي شد. يافته‌ها: شاخص روايي محتواي 79/0 براي اساتيد و 86/0 براي والدين، روايي محتواي نسخه ترجمه شده آزمون ASK را بالا نشان داد. ضريب همبستگي Spearman بين دو آزمونASK و GMFCS-E and R 901/0- است كه نشان‌ دهنده ارتباط قوي و منفي اين دو مي‌باشد. Cronbach’ alpha 997/0 نشان دهنده همبستگي درون خوشه‌اي بالاي نسخه فارسي آزمون ASK مي‌باشد. با استفاده از روش رگرسيون خطي اختلاف معني‌داري در نمرات آزمون ASK دو گروه كودكان سالم و فلج مغزي مشاهده شد كه روايي افتراقي مناسب و بالاي اين آزمون را نشان مي‌دهد. ضريب Pearson 988/0 نشان ‌دهنده همبستگي بالا بين نمرات آزمون ASK در دو بار اجراي آن و پايايي تكرار پذيري قابل قبول اين آزمون است. نتيجه‎گيري: نسخه فارسي آزمون ASK از پايايي و روايي قابل قبولي در انواع مورد بررسي برخوردار است و بنابراين مي‌تواند ابزار مناسب كلينيك‌ها و همين طور به عنوان يك ابزار تحقيقي به كار رود.

Introduction: The aim of this study was to translate "Activities Scale for Kids" (ASK) into Farsi and to determine its validity in children with cerebral palsy. Materials and Methods: In a methodological study, ASK was first translated into Farsi and then its validity and reliability was determined through a four-stage procedure. The first two phases of this four-stage procedure included cloudy translation into Farsi and back translation into English. In the third phase of this study, the validity of this test was determined through conducting a pilot study in which a group of professionals and also parents with children diagnosed as having CP rated the test. Finally, it was provided to two groups of parents (a group with children with CP and another group with children without any problems). Children with CP were recruited from the affiliated occupational therapy clinics of The University of Social Welfare and Rehabilitation Science and normal children were sampled from general population via a snowball procedure. 73 children with cerebral palsy and 69 normal children (5-15 years old) were participated in the study. Reliability (internal consistency and test-retest within a 2-week interval) and validity (content on basis of Lawascheʹs method, concurrent with GMFCS-E&R and discriminate) of ASK were analyzed using SPSS13 software. Results: Content validity index demonstrated a high content validity (0.79 for university professors and 0.86 for parents). ASK and GMFCS- E&R (-0.901) strongly negatively correlated as it was shown by Spearmanʹs correlation coefficiency. Internal consistency was assessed by Cronbakhʹs alpha and the result was 0.997. Line regression in CP and normal groups demonstrated significant statistic variation and this indicated a sophisticated discriminate validity of Farsi version of ASK. Test-retest reliability of ASK was 0.998. Conclusion: Farsi version of ASK has acceptable validity and reliability rates and it may be used for clinical as well as research purposes.
