In 1994, Sue Newman, co-founder of the Selective Mutism Foundation, requested that the fourth edition of the DSM reflect the name change from elective mutism to selective mutism and describe the disorder as a "failure" to speak. The relation to anxiety disorders was emphasized, particularly in the revised version (DSM IV-TR). As part of the reorganization of the DSM categories, the DSM-5 moved selective mutism from the section "Disorders Usually First Diagnosed in Infancy, Childhood, or Adolescence" to the section for anxiety disorders.
