چکیده
هدف از انجام مطالعة حاضر، ارزیابی ویژگیهای روان‌سنجی آزمون هماهنگی بدن در کودکان پنج تا 14 سالة شهر تهران بود. راهبرد پژوهش، توصیفی و طرح پژوهش، مقطعی بود. تعداد 306 کودک پنج تا 14 ساله به‌صورت نمونه‌گیری تصادفی خوشه‌ای از پنج منطقة شهر تهران انتخاب شدند. ابزار پژوهش، مجموعه آزمون هماهنگی درشت بدن برای کودکان (KTK) بود. برای تحلیل دادهها از روش‌های آماری تحلیل عاملی، آلفای کرونباخ، ضریب همبستگی درون‌طبقه‌ای، همبستگی پیرسون، تی مستقل و تحلیل واریانس یک‌راهه استفاده شد. پایایی همسانی درونی برای خرده‌مقیاس‌های آزمون KTK، درمجموع چهار آیتم به‌صورت 0.84 = α بود و دامنة تغییرات ضرایب آلفای کرونباخ در چهار خرده‌مقیاس آزمون KTK، 61/0 تا 97/0 به‌دست آمد (برای خرده‌مقیاس حفظ تعادل در گام‌برداشتن به عقب به‌صورت 0.81= α، پرش از روی موانع با لی‌کردن به‌صورت 0.93= α، پرش به دو طرف با هر دو پا کنار هم به‌صورت 0.96= α و جابه‌جایی سکوها یا صفحه‌های چوبی در یک جهت به‌صورت 0.92 = α. پایایی آزمون-آزمون مجدد برای هرکدام از خردهآزمونها، به‌ترتیب 0.97 = r، 0.95 = r، 0.95 = r، 0.96 = r و برای مجموع نمره‌ها، 0.95 = r به‌دست آمد. ضرایب پایایی درون‌ارزیاب و بین‌ارزیاب‌ها برای مجموع مهارت‌های هماهنگی حرکتی، به‌ترتیب برابر با 98/0 و 97/0 به‌دست آمدند. شاخص روایی محتوا برابر با 91/0 بود و روایی صوری ضرایب همبستگی پیرسون خردهآزمونها با سن، مثبت و معنادار بود. ضرایب مربوط به پایایی سازهای و روایی همگرایی مجموع خرده‌آزمونهای هماهنگی حرکتی، به‌ترتیب برابر با 87/0 و 63/0 بودند. با توجه با تأیید روایی و پایایی آزمون KTK، می‌توان با اطمینان از این ابزار برای ارزیابی هماهنگی حرکتی درشت کودکان پنج تا 14 سالة تهران استفاده کرد.

چکیده [English]
The aim of the current research was to evaluate the psychometric properties aspects (validity and reliability) of the Body Coordination Test for Children (KTK) among children of Tehran city. The strategy and design of the research were descriptive and cross-sectional, respectively. Three hundred and eight children aged 5-14 years old (0/61 male) chosen from five main districts of the city using cluster sampling. Our research tool was the Body Coordination Test for Children (KTK). The confirmatory Factor analysis by using structural equation modeling (SEM), content, face and divergent validity, internal consistency, intra- inter-class and Pearson correlation coefficients and construct reliability statistical methods were used. Content Validity Index with final value of (0.91) was obtained. The internal consistency for the total KTK was) α=0.84) and shows in a range of (0.61 to 0.97) for four subscales with 10 age bands. In addition, the reliability of test-retest for the total KTK was (r= 0.95). The intra and inter-rater reliability coefficient the sum of subscales was 0.98, 0.97 respectively. In order to evaluate the construct validity, Kiphard’s one-factor design was confirmed using Confirmatory factor analysis. Correlation coefficients of the subtests were significant and positive with age. Finally, the values of construct reliability and divergent validity were (0.87) and (0.63), respectively. Considering the confirmation of the validity and reliability of the KTK, it can be used to evaluate the body coordination of children aged (5-14) in Tehran.
