Augmented self-modeling as a treatment for children with selective mutism

Three children with selective mutism were treated with a packaged procedure that incorporated self-modeling, mystery motivators, self-reinforcement, stimulus fading, spacing, and, in one case, antidepressant medication. All three children evidenced a complete cessation of selective mutism and maintained their treatment gains at follow-up. An argument was presented for the use of a series of single-case, baseline-intervention (AB) designs appropriate for this type of school-related, lour incidence behavior. Specific conditions were met that allowed for inferences to be drawn that approached the quality of those typically obtained from experimental designs.
