Abstract Children with autism and other neurodevelopmental concerns (NDC) frequently exhibit an array of sensory processing dysfunction phenotypes, posing a significant challenge their adaptive development. Additionally, these children often encounter difficulties with self-regulation, including emotion dysregulation, anxiety, and symptoms associated with attention and hyperactivity. However, further research is required to comprehend how patterns of sensory processing differences across neurodevelopmental conditions may contribute to regulatory control problems. Adopting a transdiagnostic perspective within the Research Domain Criteria (RDoC) framework, this study examined the relationship between clusters of sensory processing phenotypes and differential patterns of self-regulation behaviors. We recruited a sample of 117 participants (8–12 years) with a diverse range of neurodevelopmental concerns including autism, ADHD, anxiety, and sensory processing differences. This study aimed to (1) establish the prevalence of self-regulation problems in a community-recruited cohort of children with diverse NDCs; (2) construct data-driven sensory processing latent subtypes; (3) investigate group differences in emotion dysregulation, anxiety, and ADHD symptoms. Results showed that 39% of NDC children met clinically concerning thresholds for emotion dysregulation, 19% for anxiety, and 62% for ADHD. Second, latent profile analysis identified five sensory processing subtypes categorized by modality: Typical Processing, Intermediate/Mixed, Sensory Over-Responsive, Sensory Seeking, and Sensory Under-Responsive. Notably, the Sensory Over-Responsive group exhibited distinctively elevated anxiety scores, while the Sensory Seeking and Sensory Under-Responsive groups showed heightened ADHD scores. Intriguingly, the Sensory Over-Responsive, Sensory Under-Responsive, and Sensory Seeking subgroups all demonstrated elevated emotion dysregulation scores, suggesting a potential shared mechanism of emotion dysregulation that might elucidate the connection between sensory processing differences and increased anxiety and ADHD behaviors in children with autism and other NDCs. |
