Selective Mutism
Selective mutism is predominantly a childhood anxiety disorder that is diagnosed when a child consistently does not speak in some situations, but speaks comfortably in other situations.
These children are unable to speak in certain social situations where there is a demand to speak, such as at school, at dance class, at soccer practice, or at the corner store. In other situations, these same children may speak openly with others and may even be considered a “chatterbox”.
Selective mutism causes significant impairment in children’s lives and can interfere with performance at school and with friends. It can often prevent them from having fun and engaging in regular childhood experiences. It also can keep them from having their personal or school needs met, as they are unable to ask for help.
How do I know if my child has selective mutism?
Your child may have selective mutism if s/he…
- Speaks in certain settings but stops talking, either completely or almost completely, when other people are around.
- Looks frozen or paralyzed (like a “deer in the headlights”) or even angry when asked questions by strangers or when s/he feels uncomfortable.
- Uses gestures like pointing, nodding, or funny facial expressions to get his or her needs met despite knowing how to talk.
And the difficulties speaking…
- Have occurred for more than one month, not including the first month of school, and are interfering with your child’s life.
- Are not better explained by another disorder.
Facts
- Most affected children and adolescents function normally in other areas of their lives and are able to learn age appropriate skills despite not speaking in some important situations.
- Less than 1 % of the population has selective mutism.
- Girls and boys are both likely to develop this disorder.
- Symptoms usually appear before the age of five but may become discernable at the beginning of school.
- Children with selective mutism often have another anxiety disorder, most often a social anxiety disorder.
What causes selective mutism?
There is no single known cause of selective mutism, but there are factors that make it more likely to develop. For example, being slow to warm up to new situations, the tendency to withdraw from new or unfamiliar situations early in life, a family history of an anxiety disorder including selective mutism, speech or language problems, and genetic factors. These factors can all play a role in the development of selective mutism.
What maintains selective mutism?
Imagine a scene where a mother and her daughter, Suzy, are at the grocery store. The mother runs into a friend that she has not seen in a long time. The friend asks, “Wow! Who is this little cutie? What’s your name?” Suzy freezes, looks scared, tearful, and clings to her mother’s arm. She is unable to respond to this seemingly easy question and a few seconds of silence occur. The friend feels horrible. She never meant to scare Suzy. The mother becomes irritated and embarrassed that Suzy is not answering the question and quickly jumps in to rescue her by saying, “Her name is Suzy.” The friend says, “Hi Suzy, so nice to meet you. You’re so cute and shy.” Suzy didn’t have to answer and everyone feels better. This scenario is common for a child with selective mutism and illustrates how not speaking due to anxiety is often reinforced by people in the child’s environment (parents, teachers, peers). The child learns that if s/he keeps quiet that others will talk for her. For children with selective mutism, this scenario happens multiple times per day. It can happen at school, in extra curricular activities, when running errands, and when relatives come over. With each “rescue” the child temporarily feels better because s/he is relieved from the anxious feelings. However, very quickly a cycle of anxious avoidance takes hold.
Within a few short months this cycle becomes an ingrained habit for the child, and for the close adults in his or her life, the cycle becomes harder and harder to break with each passing day.
How is selective mutism diagnosed and treated?
If you think that your child might have selective mutism talk to your family doctor or pediatrician to make sure that there are no developmental issues (e.g., hearing or speech delays). The next step is to ask your doctor to refer you to a psychologist or psychiatrist who will help confirm a diagnosis of selective mutism by specifically looking at where your child is verbal and non-verbal as well as evaluating for any other mental health diagnoses that may be present (e.g., other anxiety disorders.)
The main treatment for selective mutism is behaviour therapy. Behaviour therapy involves gradually exposing a child to increasingly difficult speaking tasks in the context of a supportive relationship. Practice begins with easier steps, and gets progressively harder – like climbing a ladder. Children are asked to complete tasks that they will meet with success. Success is rewarded with praise and small prizes. In time, children learn that the anxiety they feel when they are asked to speak decreases without having to avoid the situation in order to feel better.
Selective mutism in adolescence
As children get older, selective mutism becomes harder to treat because they become better practiced at anxiously avoiding situations that involve talking. The longer children miss out on important academic and social learning opportunities, the more likely they are to be impacted. Specifically, older children and teens may have difficulties with peer relationships, additional anxiety disorders such as social or generalized anxiety disorder, or depression. Older teens may also start to self-medicate with alcohol or drugs in order to ease anxious feelings. Despite the fact that it is harder and more complicated to address, excellent help can still be available. Older children and teens may need:
- Intensive and robust behavior therapy.
- Some evidence suggests that cognitive behavior therapy can be helpful with older kids with selective mutism.
- Specific interventions aimed at social skill development.
- Interventions to address other disorders, such as generalized anxiety disorder and depression, which are unlikely to go away on their own.
- Prescribed medication to help them participate in therapy.
