A two‐phase functional analysis of a profoundly retarded 19‐year‐old male's pica facilitated the design of an effective intervention containing no aversive components. In the first analysis, frequent staff‐client interaction resulted in 25% and 66% less pica than limited and no interaction, respectively. Paradoxical effects were obtained in the second analysis, where no protective helmet resulted in 38% and 26% less pica than the helmet with face shield and helmet without face shield, respectively. On the basis of these analyses, limited interaction and no helmet conditions were combined in an effective, staff‐implemented treatment at a medium‐sized institution.
