Development and Validation of a Japanese Version of the Sensory Experience Questionnaire (SEQ) 3.0: Structural Differences of Sensory Features Across Autistic Children.
TL;DR
The psychometric validity of the Japanese version of the SEQ-J for measuring sensory response patterns specific to children with ASD is supported and the structural configuration of SEQ subscores may be useful for investigating sensory features across diagnostic conditions, including ASD.
Abstract
People with autism spectrum disorder (ASD) often have unique sensory experiences. For both research and clinical purposes, tools that measure sensory features in autism are valuable; however, a gold-standard tool does not yet exist. The Sensory Experience Questionnaire (SEQ) 3.0 is a well-established caregiver-/parent-report questionnaire for autistic children and other neurodivergent individuals. This study aimed to develop and psychometrically validate the Japanese version of the SEQ 3.0 (SEQ-J). After validation, we examined the differences in sensory response patterns among children with ASD, those with other neurodevelopmental conditions, and typically developing (TD) children to determine whether the SEQ assesses ASD-specific sensory features. We recruited 154 children with ASD (44 with attention-deficit hyperactivity disorder [ADHD] and 66 with other conditions) and 156 TD children, aged 6-12 years. Confirmatory factor analyses revealed an acceptable model fit for four content factors (sensory hyper- and hyporesponsiveness, sensory interests, repetitive and seeking behaviors, and enhanced perception) and six method factors (five sensory modalities and social context) in both children with and without ASD. We performed representational similarity analyses (RSAs) on all 10 SEQ factors, comparing both between- and within-group data. The RSAs revealed no difference in within-group similarities between the ASD group with no other developmental conditions and ASD + ADHD groups, but a significant difference in the overall configuration of scores between diagnostic groups compared to other group combinations. These findings support the psychometric validity of the SEQ-J for measuring sensory response patterns specific to children with ASD. Additionally, the structural configuration of SEQ subscores may be useful for investigating sensory features across diagnostic conditions, including ASD.
