Evaluation of children with selective mutism and social phobia: a comparison of psychological and psychophysiological arousal.
Sensory avoiding is the bridge that turns selective mutism plus autism into heavy social anxiety.
01Research in Context
What this study did
The team compared kids with selective mutism only to kids with both selective mutism and autism.
They asked each child questions about social fear and strapped on sensors to check heart rate and sweat.
The goal was to see if sensory avoiding habits explain why some kids feel more social anxiety.
What they found
Children who had both selective mutism and autism reported the highest social anxiety.
Their sensory avoiding scores stood out and statistically carried the extra anxiety.
In plain words, refusing loud lights, food textures, or busy halls partly explains their bigger fear of people.
How this fits with other research
Leung et al. (2014) saw the same link in kids with autism plus migraines: more sensory hyper-reactivity went hand in hand with more anxiety.
Chezan et al. (2019) added that high sensory avoiding in autism predicts lower social and school skills a year later, so the pattern has real-life fallout.
Kalinyak et al. (2025) warns that questionnaires alone can misread social anxiety in autism; adding live conversation coding gives a fuller picture.
Together these papers say: check sensory patterns first, then double-check with multi-method data before you call it pure social anxiety.
Why it matters
If a quiet child hides behind selective mutism, run a quick sensory checklist. High avoiding scores flag possible undiagnosed autism and explain the extra anxiety you see. Pair the checklist with live observation and parent chat to be sure. This one extra step stops you from treating "shyness" when the real issue is sensory overload that needs autism-informed supports.

03Original abstract
The present study addressed the different contributors to social anxiety in children with Selective Mutism (SM), with and without co-occurring Autism Spectrum Disorder (ASD) (SM + ASD). Seventy-five parents completed an online composite questionnaire consisting of the symptoms of SM and ASD, anxiety and sensory measures. The results found the SM + ASD group showed significantly higher levels of social anxiety and sensory avoidance compared to the SM only group. However, a simple mediation model revealed sensory avoidance to be a mediator of this relationship between the diagnosis and social anxiety.. Therefore, higher levels of sensory avoidance may help to differentiate social anxiety between the groups and may also be a sign of ASD in children with SM who have and/or are yet to receive an ASD diagnosis.
