Abstract
To assess the agreement between child- and parent-reported orofacial symptoms in the Danish version of the patient questionnaire Assessment of Orofacial Symptoms in Juvenile Idiopathic Arthritis. This cross-sectional study was conducted at Aarhus University in March 2023. Eligible candidates were consecutive subjects with juvenile idiopathic arthritis (JIA) and temporomandibular joint involvement accompanied by a parental proxy for examination in the Craniofacial Clinic. After obtaining written informed consent, the questionnaire was completed individually and separately by the child and the parent without any communication between them. The level of agreement was analysed using Cohen's (weighted) kappa for nominal and ordinal outcome variables (orofacial pain frequency, pain location, jaw function, orofacial symptoms, and changes since last visit) and the intraclass correlation coefficient for linear outcome variables (orofacial pain intensity and functional disability of the jaw). The 34 included dyads had an overall 'poor' to 'moderate' child-proxy reporting agreement on the questionnaire for the assessment of JIA-related orofacial symptoms. After dividing the children into two age groups, < 13 and ≥ 13 years old, we found substantial agreement on pain frequency and moderate to excellent agreement on pain intensity for the older group. The child-proxy agreement for children aged < 13 years was slight on pain frequency and poor to moderate on pain intensity. The child-proxy reporting agreement on JIA-related orofacial symptoms is inconsistent. We suggest collecting information from both children and parents, especially when assessing orofacial pain and symptoms in children < 13 years of age.
