The case of a 9-year-old male with autism spectrum disorder (ASD) who presented with problem behavior in the form of high-frequency clothing removal is reported. Descriptive data indicated the behavior occurred when tasks were presented and commonly delayed task demands and resulted in staff attention. Two latency functional analyses with isolated and synthesized contingencies were completed to clarify the operant function of the behavior. Initial results of the synthesized analysis indicated clothing removal was sensitive to attention and escape. However, a subsequent functional analysis with isolated contingencies indicated that the behavior was maintained only by attention. A function-based intervention package consisting of attention extinction, response blocking, and differential reinforcement of other behavior (DRO) effectively reduced the frequency of clothing removal to near-zero levels. Results of the intervention were partially generalized to a new therapist. The use of latency functional analyses as a means to rapidly examine isolated and synthesized contingencies maintaining problem behavior is discussed as well as the effects of the treatment package on the behavior of clothing removal.
