Decreasing Food Stealing of Child with Prader-Willi Syndrome Through Function-Based Differential Reinforcement.

Challenging behaviors involving food are common for individuals with Prader-Willi syndrome (PWS) and often lead to obesity and other chronic health conditions. Efforts to decrease these behaviors, such as isolation during meals and strict monitoring of food consumption, can be stigmatizing. To decrease the food stealing of a 7 year-old girl with PWS, therapists conducted a latency-based functional analysis in a clinic setting before implementing a function-based intervention to facilitate her inclusion at the family dinner table.
