Behavioral inhibition (BI) may be an early indicator of selective mutism, but research on children with selective mutism's early behavioral traits is limited.
A study analyzed children aged 3-18 with selective mutism, social phobia, internalizing behaviors, and healthy controls, revealing that those with selective mutism and social phobia displayed higher levels of inhibition in their early years compared to the other groups.
The findings suggest that increased behavioral inhibition, especially towards social situations, could be a critical temperament factor linked to selective mutism, indicating a need for early screening in at-risk children.
