Cross‐cultural adaptation, validity, and reliability of the Turkish version of the Oral Behaviours Checklist

Abstract

AimDetermining the occurrence of oral parafunctional behaviors is essential for the clinical management of temporomandibular disorders (TMDs). For this reason, the evaluation of parafunctional behaviors in patients with TMDs is highly important.MethodsThe purpose of the present study was to investigate the validity and reliability of the Turkish version of the Oral Behaviours Checklist (OBC‐T) in patients with TMDs. To determine the reliability of the questionnaire, it was applied in 142 patients with TMDs twice at a 2‐week interval. For concurrent validity of the OBC, Spearman correlation analysis was performed with Fonseca Anamnestic Index (FAI), Patient Health Questionnaire‐9 (PHQ‐9), Jaw Function Limitation Scale‐20 (JFLS‐20), and Tampa Scale for Kinesiophobia for TMDs (TSK‐TMDs).ResultsItems had good to excellent test–retest reliability. The OBC‐T score was correlated with FAI, JFLS‐20, PHQ‐9, and TSK‐TMDs scores.ConclusionThese results provided important evidence that the OBC‐T can be used to evaluate parafunctional behaviors in individuals with TMDs in Turkish‐speaking populations.
