تعیین روایی و پایایی ابزار ارزیابی توانایی های دهانی- صورتی در کودکان دارای لکنت و بدون لکنت

Background and purpose: Some studies suggest motor and sensory differences between stuttering and normal subjects. One of these differences could be the difference in oral and facial sensory-motor abilities. Researches have shown that the assessment and treatment of motor and sensory disabilities can play a major role in helping stuttering children. This study aimed to investigate the validity and reliability of the Persian version of Orofacial Abilities Assessment procedure (MAMS) in children who stutter and non-stuttering children. Materials and methods: At first, the Orofacial Assessment Procedure (The Movement, Articulation, Mandibular and Sensory awareness (MAMS)) was translated into Persian and the content and face validity of MAMS was determined. Then 20 children (10 stuttering and 10 non-stuttering) were included in the study. To evaluate the reliability, the test-retest and Cronbach's alpha coefficient methods was used Results: All questions in MAMS had easy translation, and 93% were in ideal level. The ideal quality and content and face validity was achieved thoroughly by making slight changes. Significant correlation was seen in ICC for total score (P<0.002) and in test-retest scores for each parts (P<0.02). In addition, Cronbach's alpha coefficients were calculated for each section and showed the internal reliability was 71.7 to 1. Cronbach's alpha coefficient of 71.4 for the total parts was achieved. Conclusion: The results of this study showed that the Persian version of MAMS has an acceptable level of reliability and validity in assessing Children speaking in Persian language.
