Alternative response training with contingent practice as intervention for pica in a school setting (pages 219-226)


Pica is a serious challenging behavior displayed by some persons with developmental disabilities. We report the near‐elimination of automatically reinforced pica in a 7‐year‐old boy diagnosed with autism by having him practice an alternative response (discarding objects) contingent on attempted or actual pica. Intervention was implemented 6 hours per day, under naturalistic conditions in a school setting, with outcome maintained through a 4 month follow‐up phase of evaluation.
