RESUMEN

Individuals with developmental disabilities sometimes display avoidance responses such as a lack of cooperation, aggression, and vocal refusal when completing health-care routines such as dental cleanings, physicals, and haircuts. This study evaluated the effects of both graduated exposure and a differential reinforcement procedure on the acquisition, maintenance, and generalization of cooperation with dental routines. In addition, autonomic responses were used as an ancillary measure of distress or comfort and were included in the decision tree of practitioner actions. Procedures were completed in a simulated context of a dental examination. The results of this study may lead to more comprehensive treatment plans that include the use of physiological responses in addition to cooperation with procedures as an indicator that an avoidance response has been extinguished. Assessing autonomic arousal may be a useful addition to the procedures of exposing participants to dental visit routines, to improve adaptation, cooperation, and generalization.
