چکیده
برای بررسی تحرک و تعادل حرکتی، ابزار روا و پایا و سازگار با فرهنگ لازم است. هدف پژوهش حاضر، اعتباریابی نسخۀ فارسی آزمون شاخص راه‌رفتن پویا (نسخۀ چهارموردی) در بیماران مولتیپل اسکلروزیس با و بدون سابقۀ افتادن بود. پژوهش حاضر ازنوع زمینه‌یابی بود. بدین‌منظور، 55 نفر از همة بیماران مبتلا به مولتیپل اسکلروزیس شهرستان یزد در سال 1395، انتخاب شدند و نسخۀ فارسی آزمون شاخص راه‌رفتن پویا را تکمیل کردند. با استفاده از روش بازترجمه درستی ترجمۀ ابزار تأیید شد. از تحلیل عاملی تأییدی، ضریب آلفای کرونباخ و ضریب همبستگی درونطبقهای، به‌ترتیب برای بررسی روایی سازۀ عاملی، همسانی درونی و ثبات زمانی استفاده شد.نتایج پژوهش نشان‌دهندۀ برازش مطلوب نسخۀ فارسی آزمون شاخص راه‌رفتن پویا (نسخۀ چهارموردی) در بیماران مولتیپل اسکلروزیس بود؛ بهطوریکه شاخص‌های برازندگی (رمزی برابر با 08/0، سی.اِف.آی. برابر با 99/0 و تی.اِل.آی. برابر با 97/0)، همسانی درونی برابر با 93/0 و پایایی زمانی برابر با 70/0، به‌ترتیب بیانگر روایی سازۀ عاملی و پایایی مطلوب (درونی و زمانی) نسخۀ فارسی آزمون شاخص راه‌رفتن پویا (نسخۀ چهارموردی) در بیماران مولتیپل اسکلروزیس بودند. نتایج پژوهش حاضر نشان داد که نسخۀ فارسی آزمون شاخص راه‌رفتن پویا (نسخۀ چهارموردی) در بیماران مولتیپل اسکلروزیس ابزاری روا و پایا است؛ بنابراین، میتوان از آن در محیط‌های بالینی، درمانی و پژوهشی برای بررسی وضعیت تعادلی بیماران مولتیپل اسکلروزیس که درمعرض خطر زمین‌خوردن هستند، استفاده کرد.

چکیده [English]
For measuring motor balance and mobility we need reliable & valid instrument witch adapted with culture. The present study aims to assess psychometric features of a Persian version of 4-Item dynamic gait index test for patients with multiple sclerosis (MS; with/without history of falling). By taking a survey-based approach, 55 MS patients in year 2016 from Yazd were randomly selected and complete Persian version of 4-Item dynamic gait index test. Face validity was confirmed through translation-retranslation. Construct validity was assessed through confirmatory factor analysis (CFA) while internal consistency and temporal reliability were evaluated using Cronbach’s alpha and intraclass correlation, respectively. Our findings indicate desirable fit of the Persian version of 4-Item dynamic gait index test for MS patients. Indices of fit (RMSEA=0.08, CFI=0.99, TLI= 0.97), internal consistency (0.93), and temporal reliability (P ≥ 0.70) suggest proper validity and reliability of the Persian version of 4-Item dynamic index for MS patients. The results showed that the Persian version of 4-Item dynamic gait index is a valid and reliable instrument for MS patients that can be used in clinical, treatment, and research settings to identify MS patients prone to the risk of falling.
