Abstract/Summary

Children with neurodevelopmental conditions (NDC) often have sensory reactivity differences, such as being overwhelmed by sounds, which can elicit distress in their everyday life. Furthermore, children with an NDC often present with a greater frequency of mental health symptoms compared to their typically developing peers. However little research has examined the relationship of these sensory reactivity differences on broader mental health. This study set out to explore the relationship between sensory reactivity and mental health symptoms. Data from parent-reported measures of sensory reactivity and mental health symptoms were collected for 49 children presenting with a neurodevelopmental condition and 42 typically developing (TD) controls. Partial correlational analyses, controlling for IQ, were used to elucidate the relationship between sensory reactivity and mental health symptoms. Children with an NDC were significantly more likely to present with a sensory reactivity difference or mental health symptom. Sensory seeking was found to be the sensory subtype most related to mental health symptoms, especially in externalising conditions. There was evidence also found for a relationship between depression, sensory seeking and sensory hypo-reactivity, and GAD and hyper-reactivity. Findings suggest a relationship between sensory reactivity and mental health symptoms in children with a neurodevelopmental condition. There is also preliminary evidence of unique sensory-based profiles of mental health. Assessment of sensory difficulties as part of more rigorous mental health assessments within mental health services will support more accurate diagnoses and intervention.
