پايايي مجموعه آزمون سنجش حركت كودكان-ويرايش دوم (MABC-2) در كودكان 7 تا 10 ساله شهر تهران

Reliability of the Movement Assessment Battery for Children - Second Edition (MABC-2) in Children Aged 7-10 Years in Tehran

مقدمه و اهداف براي تشخيص اختلال هماهنگي رشدي به يك ابزار استاندارد و دقيق براي سنجش مهارت­ هاي حركتي نياز است. مجموعه سنجش حركت كودكان-ويرايش دوم، يكي از ابزارهايي است كه بدين منظور ساخته شده و در كشورهاي انگليسي ­زبان (بريتانيا و امريكا) مورد استفاده قرار مي­ گيرد. پس براي استفاده از آن در جامعه تهران نياز است كه پايايي اين آزمون بررسي شود. هدف از تحقيق حاضر، تعيين پايايي اين مجموعه آزمون براي كودكان رده دوم سني (10-7 سال) شهر تهران بود. مواد و روش ­ها جامعه آماري پژوهش حاضر را كليه كودكان 7 تا 10 ساله شهر تهران تشكيل دادند. نمونه اين پژوهش شامل 800 نفر از كودكان عادي با رشد طبيعي با دامنه سني 0/7 تا 10/8 ساله (ميانگين 8/8 و انحراف معيار 1/2) شد كه به روش نمونه­ گيري تصادفي چندمرحله­ اي انتخاب شدند. ابزار استفاده ­شده در اين پژوهش، مجموعه آزمون سنجش حركت كودكان-ويرايش دوم بود. در اين مطالعه، پايايي بين آزمون گرها و آزمون-آزمون مجدد و همساني دروني براي نمونه ايراني بررسي گرديد. پايايي بين آزمون گرها با دو آزمون گر روي 50 كودك، پايايي آزمون-آزمون مجدد با فاصله دو هفته بين دو آزمون و روي 75 كودك و پايايي همساني دروني روي 800 كودك به دست آمد. كليه مراحل تجزيه و تحليل داده ­ها با استفاده از نرم ­افزار SPSS نسخه 23 انجام شد و سطح معناداري تمام آزمون­ها 0/05

Background and Aim: To diagnose developmental coordination disorder, a standard and accurate instrument for assessment of motor skills is required. The Movement Assessment Battery for Children - Second Edition is one of the tools developed for this purpose and is used in English-speaking countries (Britain and America). Therefore, it is necessary to examine the reliability of this test for use in Iranain society. The purpose of the present study was to determine the reliability of this test for age band two (7 to 10 years) children in Tehran. Materials and Methods: The statistical population of the study consisted of all 7-10 year-old children in Tehran. The sample consisted of 800 typical children with normal growth with a range of 0/7 to 10/8 years (mean 8.8 and 1.2 standard deviation) selected using multistage random sampling. The instrument used in the study was the Movement Assessment Battery For Children - Second Edition. We analyzed the inter-tester reliability and the test-retest and internal consistency for the Iranian sample. Inter-tester reliability was performed with two testers on 50 children, Test-retest reliability with two weeks interval between two tests and on 75 children, and internal consistency reliability was evaluated on 800 children. All steps of data analyses were performed using SPSS, version 23, and the significance level was set at p <0.05. Results: Inter-tester reliability was calculated by calculating the intraclass correlation coefficient for manual dexterity to be 0/923, aiming and catching 0/999, balance 0/988, and the total score of test was calculated to be 0/985. Test-retest reliability was calculated by calculating the inter-class correlation coefficient for manual dexterity to be 0/926, aiming and catching 0/888, balance 0/967, and the total score of test was calculated to be 0/967. The Cronbach's alpha coefficient for the internal consistency of the test was 0/713 for manual dexterity, aiming and catching0/765, balance 0/603, and the total score was calculated to be 0/843. Conclusion: Based on the findings of the present study, it is concluded that The Movement Assessment Battery for Children - Second Edition is a reliable tool for diagnosing the developmental coordination disorder in children aged 7-10 years in Tehran.
