Emerging adults with autism spectrum disorder (ASD) experiencing problem behaviors often have heightened sensory responses and anxiety. These interconnected issues suggest shared underlying mechanisms, impacting individuals with ASD.
Area of Science:
- Neurodevelopmental disorders
- Clinical psychology
- Sensory processing
Background:
- Autism spectrum disorder (ASD) is frequently associated with sensory over-responsivity, problem behaviors, and anxiety in emerging adults.
- The interplay between these conditions in this demographic remains underexplored, necessitating further investigation.
Purpose of the Study:
- To investigate the relationships between sensory over-responsivity, problem behaviors, and anxiety in emerging adults with ASD.
- To clarify the potential mediating role of anxiety in the association between sensory processing differences and behavioral challenges.
Main Methods:
- A cohort of 57 emerging adults diagnosed with ASD participated in the study.
- Standardized assessments were employed, including the Adult Sensory Profile, Problem Behavior Scale, and Generalized Anxiety Disorder-7 (GAD-7).
Main Results:
- Significant correlations were found between sensory sensitivity/avoiding and problem behaviors.
- Anxiety emerged as a significant mediator, explaining the link between sensory over-responsivity and problem behaviors.
- High prevalence rates of sensory over-responsivity (sensation sensitivity and avoiding) and various problem behaviors (internalizing, externalizing, asocial) were observed.
Conclusions:
- Emerging adults with ASD exhibiting problem behaviors may concurrently experience heightened sensory reactivity and anxiety symptoms.
- The findings suggest common underlying mechanisms linking sensory over-responsivity, problem behaviors, and anxiety in this population.
- Understanding these connections is crucial for developing targeted interventions for emerging adults with ASD.

Autism Spectrum Disorder
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Social Anxiety Disorder
Anxiety: Overview
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
