Development and application of a questionnaire to evaluate signs of temporomandibular disorder observed by caregivers of children with autism spectrum disorder

Objective: This study aimed to develop and validate a questionnaire to detect signs of temporomandibular disorders (TMD), verifying whether the perception of signs observed by caregivers of non-verbal autistic children are the same as those observed by caregivers of verbal ones.

Methods: This is a cross-sectional, exploratory and analytical study. The sample consisted of forty individuals with Autism Spectrum Disorders (ASD), thirty non-verbal and ten verbal, besides their respective caregivers. For this, an experimental questionnaire was applied and compared to the European Academy of Orofacial Pain (EAOP) questionnaire, which is already validated and widely used throughout the world. All responses were compared using the chi-square test and the questionnaires were compared with the McNemar test, considering p < .05.

Results: When comparing the number of coincident responses to the questionnaire between caregivers and children, the mean was 8.2 ± 1.61 responses. After performing the binomial test, no statistically significant discrepancy was found between the results of the two tests adopted when the questionnaires were compared (Mc Nemar test, p > .05) CONCLUSION: The development of this questionnaire and its validation serve as a support for health professionals in the TMD area, for the detection of TMD in non-verbal autistic children, providing them and their caregivers, who are faced with several difficulties in their day-by-day, a facilitating instrument.
