Abstract
AbstractObjectiveThe aim of this study was to investigate the validity and reliability of the Turkish version of the Oral Behavior Checklist (OBC‐TR).Materials and MethodsThe study included 223 patients with temporomandibular disorders (TMDs) and 94 individuals without TMD. Face and content validity were analyzed. Structural (with confirmatory factor analysis [CFA]), convergent (with pain intensity, Fonseca Anamnestic Index [FAI], Hospital Anxiety and Depression Scale [HADS], and Oral Health Impact Profile [OHIP‐14]), divergent (with active pain‐free maximum mouth opening [MMO]), and discriminant validity were investigated to evaluate the construct validity. Cronbach's alpha for internal consistency and the intraclass correlation coefficient (ICC) for test–retest reliability were computed.ResultsFace and content validity were satisfactory. The CFA has verified the structural validity of the OBC‐TR. Strong associations between the OBC‐TR score and pain intensity (r = 0.88), FAI (r = 0.90), HADS (r = 0.82–0.86), and OHIP‐14 (r = 0.83) scores, and MMO (r = −0.85) verified the convergent and divergent validity of the OBC‐TR. Concerning discriminant validity, the OBC‐TR discriminated between patients with TMD and individuals without TMD (p < 0.05). Internal consistency (Cronbach's alpha = 0.89) and test–retest reliability (ICC = 0.91) were satisfactory.ConclusionThe OBC‐TR is a valid and reliable instrument to measure the frequency of oral parafunctional behaviors in Turkish‐speaking patients with TMD.
