چکیده

پژوهش حاضر با هدف بررسی اثربخشی تحریک الکتریکی فراجمجمه‌ای با جریان مستقیم بر حافظه کاری و بازداری پاسخ در کودکان مبتلا به اوتیسم شهر زاهدان انجام شد. این پژوهش، از لحاظ هدف کاربردی و از نظر روش از نوع شبه آزمایشی با طرح پیش‌آزمون-پس‌آزمون با گروه کنترل بود. جامعه آماری این پژوهش شامل تمامی کودکان 10 تا 12 ساله دارای اختلال طیف اوتیسم بودند که به مراکز درمانی شهر زاهدان در سال 1402-1401 مراجعه کردند و تعداد 30 نفر از این کودکان با عملکرد بالا (کسب نمره بالای 85 در آزمون گیلیام و ضریب هوشی بالای 85 بر اساس پرونده کودک در مرکز درمانی)، به عنوان نمونه آماری به روش هدفمند انتخاب و در دو گروه 15 نفر (یک گروه آزمایش و یک گروه گواه) به صورت تصادفی جایگزین شدند. افراد موردنظر از طریق مقیاس تشخیص اوتیسم گیلیام (GARS)، آزمون استروپ (ST)، مقیاس هوش وکسلر کودکان ویرایش پنجم (WISC-5) و پروتکل تحریک الکتریکی فراجمجمه‌ای با جریان مستقیم (tDCS) مورد سنجش قرار گرفتند. بررسی روابط متغیرها به وسیله‌ی آزمون کوواریانس تک متغیره انجام شد. نتایج نشان داد بین پس آزمون نمرات حافظه کاری و بازداری پاسخ گروه آزمایش با نمرات حافظه کاری و بازداری پاسخ در گروه گواه تفاوت معناداری وجود دارد و تحریک الکتریکی فراجمجمه‌ای با جریان مستقیم بر حافظه کاری و بازداری پاسخ به طور قابل توجهی اثربخشی دارد. بنابراین تحریک الکتریکی فراجمجمه‌ای، مکمل سودمندی جهت بهبود و تقویت حافظه کاری و بازداری پاسخ در کودکان مبتلا به اوتیسم می‌باشد.

چکیده [English]

The present study was conducted with the aim of investigating the effectiveness of direct current transcranial electrical stimulation on working memory and response inhibition in children with autism in Zahedan. This research was practical in terms of purpose and quasi-experimental in terms of method with a pre-test-post-test design with a control group. The statistical population of this research included all children aged 10 to 12 with autism spectrum disorder who referred to the treatment centers of Zahedan city in 1402-1401 and 30 of these children with high performance (achieving a score above 85 in the Gilliam test and an IQ above 85 based on the child's file in the treatment center), were selected as a statistical sample using a targeted method and divided into two groups of 15 people (an experimental group and a control group) were randomly replaced. Subjects were evaluated through Gilliam Autism Diagnostic Scale (GARS), Stroop Test (ST), Wechsler Intelligence Scale for Children 5th Edition (WISC-5) and Transcranial Direct Current Electrical Stimulation protocol. Investigating the relationships between variables was done by univariate covariance test. The results showed that there is a significant difference between the post-test scores of working memory and response inhibition of the experimental group with the scores of working memory and response inhibition in the control group, and transcranial electrical stimulation with direct current is significantly effective on working memory and response inhibition. Therefore, transcranial electrical stimulation is a useful supplement to improve and strengthen working memory and response inhibition in children with autism.
