Assessment and Treatment of Challenging Behavior Maintained by a Nonvocal Mands Function.

Abstract

Standard functional analysis procedures may require modifications to assess idiosyncratic variables, such as adult compliance with mands. In the literature, the mands function is largely represented by individuals who vocally communicate idiosyncratic requests. Although effective treatment procedures have been published, schedule thinning has rarely been conducted. Using a reversal design, a mands functional analysis was completed with a 12-year-old nonvocal male. Results showed differentiated rates of challenging behavior. Treatment consisted of differential reinforcement via a chained schedule with signaled availability. During schedule thinning, low rates of challenging behavior were maintained.
