BackgroundThe 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.
ObjectivesThe 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.
MethodsTwo hundred and eighty-two TMD-free students, divided into 2 groups (Group A, n=139, mean ageSD=22.65.4years; Group B, n=143, 23.7 +/- 4.2years), 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 2weeks, both groups filled in the OBC-It again. However, Group B was further divided into 2 subgroups, B-1 and B-2. The first received the same instructions again, while B-2 did not.
ResultsThe test-retest reliability of the OBC-It (A: ICC=.87; B-1: ICC=.94; B-2: ICC=.95) and OBC-It 6 (A: ICC=.85; B-1: ICC=.89; B-2: ICC=.93) was excellent in all groups. Trait anxiety was weakly associated with OBC-It only in women (R-2=.043, P=.021).
ConclusionsThe OBC-It is a reliable tool but further subjects' instructions might be needed. Trait anxiety has a limited effect on oral behaviours in TMD-free subjects.
