Self and caregiver report measurement of sensory features in autism spectrum disorder: a systematic review of psychometric properties

Background Unusual responses to sensory stimuli are considered a diagnostic symptom of autism spectrum disorder with mounting research efforts put towards understanding, characterizing, and treating such symptoms. Methods This paper examines self and caregiver report tools used to measure sensory features in ASD through a systematic review of the psychometric evidence for their use. A total of 31 empirical papers were reviewed across 20 assessment tools. Substantial differences were identified in the specific sensory features defined across assessment tools. Sensory assessment questionnaires were evaluated against quality psychometric evidence criteria to provide a use recommendation. Results Five assessments were identified to be “appropriate with conditions,” while no sensory assessment tools were identified to have sufficient quality psychometric evidence to provide a recommendation of “Appropriate” for measuring sensory features in ASD. Conclusion Evidence from this review highlights potentially significant shortcomings among the current methods used to measure sensory features in ASD and suggests the need for more efforts in developing psychometrically sound sensory assessment tools for use in ASD populations.
