Sensory processing differences are widely reported in autism. However, our understanding of sensory profiles in this population has been complicated due to the heterogeneous presentation of sensory symptoms. We addressed this by using latent profile analysis, allowing for the identification of more homogeneous sensory classes in a large cohort (n = 211 (52 females), 2-4 years) of autistic children using subscale scores from the Short Sensory Profile. Based on the patterns of both severity and sensory modality, four classes emerged: "Moderate/Mixed" (35.5%), "Severe/Mixed" (8.5%), "Moderate/Broad" (14.6%), and "Low/Mixed" (41.1%). While a subset of children displayed normative sensory-related behaviors, the majority showed a combination of both hypo- and hyper-reactivity across various sensory modalities. Subsequent analyses showed that the class characterized by "Severe/Mixed" sensory differences exhibited greater problems in a variety of areas such as social and adaptive skills and attention-deficit/hyperactivity disorder symptoms, whereas the "Low/Mixed" class showed overall fewer problems. Identification of homogeneous classes may be useful for neurophysiological/imaging studies focusing on studying underlying mechanisms linked with specific sensory patterns. These findings may help clinicians identify children with particular sensory profiles that might relate to other social, adaptive, or behavioral domains with potential implications for intervention.
