Sex-Related Specificities of Sensory Profiles in Autism Spectrum Disorder: Impact on Clinical Functioning

Background and Objectives: Sensory anomalies are a distinctive feature of Autism Spectrum Disorder (ASD) individuals and appear to differ in intensity, frequency, and subtype between male and female subjects. According to the diagnostic framework of the DSM-5-TR, these sensory patterns are key clinical indicators. The objectives of this study were to investigate sensoriality in ASD, to compare sensory profiles in ASD subjects of both sexes and evaluate potential correlations with clinical profiles. Materials and Methods: A total of 94 ASD participants were enrolled at the Children and Adolescents Neuropsychiatry Department of the University of Naples Federico II. The population was assessed through psychometric (cognitive and adaptive levels, and intensity of autism symptoms) and sensory characterization (using the Short Sensory Profile questionnaire). Subsequently, a Mann-Whitney U test was performed to evaluate differences in sensory profiles between males and females. Spearman's correlation was used to assess significant associations between the sensory profile and cognitive level, adaptive level, and ASD symptom intensity. Subsequently, for the correlations that emerged as significant, an analysis was performed using a General Linear Model (GLM), including age and Intelligence Quotient (IQ) as covariates in the model.
