Background: The Oral Behaviours Checklist (OBC) is a valid 21-item instrument quantifying the self-reported frequency of oral behaviours. An Italian version (OBC-It) has been released recently. Anxiety and oral behaviours are known to be associated in individuals with oro-facial pain due to temporomandibular disorders (TMD). However, information about this relationship in pain-free individuals is still limited. Objectives: The aim of this study was to test the reliability of the OBC-It and its reduced version (OBC-It 6), focusing on tooth clenching-related wake-time oral behaviours, and the effect of patient instructions on reliability. A second aim was to test the association between trait anxiety and oral behaviours in pain-free individuals. Methods: Two hundred and eighty-two TMD-free students, divided into 2 groups (Group A, nÂ =Â 139, mean ageÂ Â±Â SDÂ =Â 22.6Â Â±Â 5.4Â years; Group B, nÂ =Â 143, 23.7Â Â±Â 4.2Â years), filled in the State-Trait Anxiety Inventory and the OBC-It. Group B received instructions about the OBC-It, while Group A did not. After 2Â weeks, both groups filled in the OBC-It again. However, Group B was further divided into 2 subgroups, B1and B2. The first received the same instructions again, while B2did not. Results: The test-retest reliability of the OBC-It (A: ICCÂ =.87; B1: ICCÂ =.94; B2: ICCÂ =.95) and OBC-It 6 (A: ICCÂ =.85; B1: ICCÂ =.89; B2: ICCÂ =.93) was excellent in all groups. Trait anxiety was weakly associated with OBC-It only in women (R2Â =.043, PÂ =.021). Conclusions: The OBC-It is a reliable tool but further subjectsâ instructions might be needed. Trait anxiety has a limited effect on oral behaviours in TMD-free subjects.
