RESUMO
OBJECTIVE: Hyperacusis is reported to occur in 3.2-17.1% of the general paediatric population with higher rates in clinical populations such as autism spectrum disorders (ASD). Although hyperacusis is a relatively common form of decreased sound tolerance (DST), no valid paediatric hyperacusis measures are currently available. The purpose of the present study was to develop and validate a paediatric version of the Khalfa Hyperacusis Questionnaire (HQ) as a first step towards filling this measurement gap. DESIGN: A cross-sectional design was used to evaluate therapist opinions of the paediatric version (P-HQ) and to field test the P-HQ in parents of children with and without ASD. Total scores were compared between ASD and non-ASD groups. STUDY SAMPLE: Eleven paediatric occupational and speech therapists with expertise in ASD, 64 parents of children with ASD and 37 parents of children without ASD completed online questionnaires. Psychometric analyses were conducted. RESULTS: A unidimensional construct was found underlying P-HQ and all items displayed sufficient theoretical relevance to hyperacusis and adequate psychometric properties. CONCLUSIONS: The P-HQ demonstrates good internal consistency and shows promise as a potential screening tool for identifying DST in ASD. Further research is warranted to establish normative data and validate cut-off scores.
