Selective Mutism in Adults

Specialist Assessment, Diagnosis Support & Therapy Across the UK

Many people assume selective mutism only affects children. In reality, selective mutism can continue into adulthood, often remaining misunderstood, misdiagnosed or masked for years.

At Independent Speech & Language Therapy Services Ltd (ISLTS), we provide specialist support for adults experiencing selective mutism, including assessment, diagnosis support and therapy tailored to real-life situations such as work, education, relationships and everyday communication.

We work with adults nationwide through online and in-person appointments. 

What is Selective Mutism?

Selective mutism is an anxiety disorder where a person is physically unable to speak in certain situations, despite being able to speak comfortably in others. It is not a choice, refusal or behavioural issue. 

Many adults with selective mutism describe:

  • Feeling “frozen” when expected to speak
  • Being able to talk freely with trusted people but not in work, social or public situations
  • Avoiding phone calls, meetings or appointments
  • Anxiety around introductions, ordering food or speaking in groups
  • Being misunderstood as shy, rude or disengaged

Selective mutism is increasingly recognised as an anxiety condition that can persist into adulthood if unsupported. 

Selective Mutism in Adults Can Often Go Unrecognised

Many adults seeking support tell us they:

  • Were labelled “extremely shy” as children
  • Learned coping strategies to avoid speaking situations
  • Experience significant anxiety around communication
  • Have never previously received assessment or support
  • Feel exhausted by masking or avoidance behaviours

Because adults with selective mutism often develop sophisticated coping strategies, the condition can sometimes be overlooked or mistaken for social anxiety alone.

Frequently Asked Questions

Selective Mutism (sometimes called Situational Mutism) is an anxiety based condition where a person is unable to speak in certain situations, such as sin meetings, despite being able to speak comfortably in others, like at home.

  • Anxiety disorders, especially social anxiety
  • Highly inhibited or shy temperament

Common signs include not speaking in specific settings, relying on gestures or whispering, freezing when expected to talk, and appearing anxious or withdrawn in social situations.

Diagnosis involves assessment by professionals who look at speech patterns, anxiety levels, and whether difficulties occur only in certain settings.



Treatment focuses on reducing anxiety, building confidence, and gradually increasing speaking in situations that feel safe. Collaborating with home and educational placements to reduce pressure and build confidence using positive reinforcement and removing any punishment for not speaking, with support from speech and language therapists or psychologists.
