The successful treatment of long-term selective mutism: a case study

This study describes the successful treatment of a seventh grade boy who had selective mutism in school since kindergarten. Treatment consisted of systematic desensitization, consultation with school personnel, and training in social speaking skills. The student made significant gains with respect to frequency of verbalizations to teachers and peers, number of individuals spoken to, anxiety related to speaking, school attendance, and involvement in school-based extracurricular activities. At one year follow-up, the student's rate of speech was indistinguishable from his classmates'. Special issues concerning the treatment of long-term selective mutism are discussed.
