简要总结
The purpose of this study is to test if the translated Arabic version of the (jaw functional limitation scale -8) JFLS_8 , valid (face, content, feasibility) ,reliable (internal consistency, test retest) and culturally adapted enough to quantify the impact of temporomandibular joint (TMJ) disorders on jow function in arabic people or not?
详细描述
Temporomandibular disorders (TMD) are relatively prevalent among adults, representing a considerable health concern. These disorders negatively affect psychological well-being and overall quality of life, highlighting the importance of accurate assessment and appropriate management strategies. Consequently, there is a growing need for reliable and efficient tools to assess functional limitations associated with TMD.
The Jaw Functional Limitation Scale with 8 items (JFLS-8) is a concise, valid, and reliable instrument used for the assessment of functional limitations related to the masticatory system. It was developed as a shorter version of the JFLS-20 and has been shown to be more practical for use in busy clinical settings while maintaining strong psychometric properties. The JFLS-8 has demonstrated excellent validity and reliability and has been successfully translated and culturally adapted into several languages, confirming its effectiveness as a clinical assessment tool.
Therefore, there is a clear need to translate the JFLS-8 into an Arabic version, perform cultural adaptation, and evaluate its validity and reliability among patients with temporomandibular disorders in Arabic-speaking populations.

结局指标
主要结局
Face Validity of the Arabic Version of the 8-item Jaw Functional Limitation Scale (JFLS-8)
时间窗: 30 minutes
It will be assessed using the Clarity Index and Expert Proportion of Clearance, judged by two expert panels (5 experts each) to evaluate whether the scale appears clear and relevant.
Content Validity of the Arabic Version of the 8-item Jaw Functional Limitation Scale (JFLS-8)
时间窗: 30 minutes
It will be assessed using the Content Validity Index (CVI) and Expert Proportion of Relevance, to confirm that the 8 items adequately cover the construct of jaw functional limitation.
Feasibility of the Arabic Version of the 8-item Jaw Functional Limitation Scale (JFLS-8)
时间窗: 30 minutes
It will be evaluated by two factors: time needed to complete the questionnaire and the missed item index (ratio of unanswered items).
Internal Consistency Reliability of the Arabic Version of the 8-item Jaw Functional Limitation Scale (JFLS-8)
时间窗: 30 minutes
It will be measured using Cronbach's alpha to confirm that all 8 items are measuring the same underlying construct.
Test-Retest Reliability of the Arabic Version of the 8-item Jaw Functional Limitation Scale (JFLS-8)
时间窗: 2 days
It will be assessed using Spearman's rank correlation coefficient, with a subset of patients completing the JFLS-8 again after 2 days under the same conditions.
次要结局
- Visual Analogue Scale (VAS)(30 minutes)
- Fonseca Anamnestic Index (FAI)(30 minutes)
