چکیده

مقدمه و اهداف
خطاهای گفتاری کودکان با سندرم داون معمولاً بی­ثبات هستند، به­طوری­که کودک در هر بار تولید یک گزینه واژگانی آن را به­صورت­های مختلف تولید می­کند. مداخله واژگان پایه برای افزایش ثبات تولیدی در کودکان دارای اختلال بی­ثباتی گفتار طراحی شده است. هدف مطالعه حاضر، بررسی اثربخشی مداخله واژگان پایه بر وضوح گفتار کودکان با سندرم داون آموزش­پذیر 11-7 فارسی زبان بود.
مواد و روش­ها
مطالعه حاضر در قالب یک طرح پیش­آزمون-پس­آزمون انجام شد. 4 کودک با سندرم داون 11-7 ساله در پژوهش حاضر شرکت داشتند. برای هر آزمودنی 12 تا 14 جلسه درمانی برگزار شد. درمان از طریق 70 واژه هدف صورت گرفت. تعمیم ثبات تولیدی از طریق واژه­های کنترل ارزیابی شد. ابزارهای مورد استفاده عبارتند از: آزمون بی­ثباتی نسخه فارسی مجموعه آزمون ارزیابی تشخیصی آوایی و واجی و آزمون وضوح تک کلمات. 7 نقطه ارزیابی در مطالعه حاضر وجود داشت: 2هفته قبل از مداخله، 1هفته قبل از مداخله، درست قبل از مداخله، درست بعد از مداخله، 1هفته بعد از مداخله، 2 هفته بعد از مداخله و 6 ماه بعد از مداخله. علاوه بر این 10 شنونده ناآشنا وضوح گفتار کودکان را از طریق صدای ضبط شده آن­ها قبل و بعد از اجرای مداخله قضاوت کردند.
یافته­ها
ثبات تولیدی در تولید تک کلمات بعد از اجرای مداخله واژگان پایه افزایش پیدا کرد. همچنین ثبات تولیدی به­دست آمده به واژه­های کنترل نیز تعمیم یافت. علاوه بر این وضوح گفتار کودکان نیز بعد از اجرای مداخله افزایش یافت (05/0P<).
بحث و نتیجه­ گیری
نتایج به­دست آمده در راستای نتایج سایر مطالعات، مبنی بر موثر بودن مداخله واژگان پایه در افزایش ثبات تولیدی است. مطالعات بیشتری جهت اطمینان از اثربخشی و اندازه اثر مداخله واژگان پایه در افزایش ثبات و صحت تولیدی و افزایش وضوح گفتار در زبان­های دیگر لازم است.

چکیده [English]

Background and Aim: Speech errors in children with Down Syndrome (DS) are inconsistent, such that in articulating the same lexical item, the children produce it in different ways. The Core Vocabulary Treatment (CVT) has been designed to increase the consistency of articulation in children with inconsistent disorder. The current study was carried out to investigate the efficacy of CVT on the speech intelligibility of 7-11-year-old educable Farsi-speaking DS children.
Materials and Methods: The study was performed in the form of a pre-posttest design. Four DS children participated in the study. For each case, 12 to 14 treatment sessions were performed. Treatment was accomplished by 70 goal words. The instruments used were Inconsistent subtest of Persian Diagnostic Evaluation of Articulation and Phonology (P-DEAP) and the test of single word intelligibility. There were 7 assessment points in the study: two weeks, one week, and immediately before intervention as well as immediately, one week, two weeks, and six months after the intervention. Subsequently, 10 unfamiliar listeners judged the speech intelligibility in children by recording their speech prior to and after intervention.
Results: The consistency of articulation increased after intervention and generalized to control words. Furthermore, intelligibility of speech also increased after the intervention (P<0.05).
Conclusion: The obtained results, similar to those of other studies, showed that CVT is effective in enhancing the consistency of articulation. Further studies are necessary to ensure confidence in the effectiveness of this intervention to increase the consistency and intelligibility of speech in other languages.
