Case study: audio feedforward treatment of selective mutism.

Selective mutism is a relatively rare and difficult-to-treat disorder. Audio feedforward is a potential intervention that involves having the individual with selective mutism listen to audiotapes edited to depict him or her speaking in situations in which he or she is not currently speaking. The successful use of this intervention for three children with selective mutism is reported. The intervention was used in both school and community settings. This intervention has not always proved successful, sometimes because children refused to make the audiotapes.
