Abstract

Purpose: This study aimed to translate the 20-item Jaw Functional Limitation Scale (JFLS-20) into Turkish (JFLS-20-TR) and investigate the psychometric properties of the JFLS-20-TR.

Methods: This study included 232 patients with temporomandibular disorder (TMD) and 130 individuals without TMD. Structural (with confirmatory factor analysis [CFA]), convergent (with pain intensity, Fonseca Anamnestic Index [FAI], and Oral Health Impact Profile [OHIP-14]), discriminant (with maximum mouth opening [MMO]) and known-group validity were investigated to assess the construct validity. Cronbach's alpha for internal consistency and the intraclass correlation coefficient (ICC_2,1) for test-retest reliability were calculated. Additionally, content and face validity, smallest detectable change (SDC₉₅), and floor/ceiling effects were evaluated.

Results: According to CFA, the model fit indices were acceptable for JFLS-20-TR, confirming structural validity. Strong correlations were found between the global and subdomain scores of the JFLS-20-TR and pain intensity (r ≥ 0.80), FAI (r ≥ 0.83), OHIP-14 (r ≥ 0.76), and MMO (r ≥ -0.79) scores, confirmed the convergent and discriminant validity of the JFLS-20-TR. In addition, JFLS-20-TR differentiated between patients with TMD and individuals without TMD (p < .05). Internal consistency (Cronbach's alpha values: 0.91-0.93) was excellent, and test-retest reliability (ICC_2,1 values: 0.91-0.95) was high. Content and face validity were satisfactory. The SDC₉₅ values ranged from 0.79 to 1.43. No floor or ceiling effects were observed.

Conclusion: The JFLS-20-TR is a valid, reliable, and useful tool for assessing jaw functional limitations in Turkish-speaking patients with TMD.

土耳其版 20 项颌骨功能限制量表的有效性和可靠性。

目的：本研究旨在将 20 个项目的颚功能限制量表（JFLS-20）翻译成土耳其语（JFLS-20-TR），并调查 JFLS-20-TR 的心理测量特性：本研究包括 232 名颞下颌关节紊乱症 (TMD) 患者和 130 名无 TMD 患者。通过结构效度（采用确认性因子分析[CFA]）、收敛效度（采用疼痛强度、丰塞卡内科指数[FAI]和口腔健康影响档案[OHIP-14]）、判别效度（采用最大张口度[MMO]）和已知群体效度进行了研究。计算了内部一致性的 Cronbach's alpha 和测试-再测可靠性的类内相关系数 (ICC2,1)。此外，还评估了内容效度和表面效度、最小可测变化（SDC95）以及上下限效应：根据 CFA，JFLS-20-TR 的模型拟合指数是可接受的，证实了结构效度。JFLS-20-TR的全域和分域得分与疼痛强度（r≥0.80）、FAI（r≥0.83）、OHIP-14（r≥0.76）和MMO（r≥-0.79）得分之间存在很强的相关性，证实了JFLS-20-TR的收敛性和鉴别性。此外，JFLS-20-TR 对 TMD 患者和非 TMD 患者的区分度很高（p 2,1 值：0.91-0.95）。内容效度和表面效度均令人满意。SDC95 值在 0.79 至 1.43 之间。没有观察到最低或最高效应：JFLS-20-TR是一种有效、可靠且实用的工具，可用于评估讲土耳其语的TMD患者的下颌功能限制。
