participants in this study achieved long term results, highlighting the need for a collaborative team approach to treatment across several disciplines to include PCP, dermatology, psychology and psychiatry as needed. Developmentally disabled Several different behavioral interventions have been tested to treat excoriation disorder in those with developmental disabilities. One method is to have individuals wear a form of protective clothing that limits the ability of the patient to pick at their body, e.g., gloves or face mask. Other behavioral treatments attempt to change behavior by providing different incentives. Under Differential Reinforcement of Other Behavior (DRO), a patient is rewarded if able to abstain from the picking behavior for a certain amount of time. In contrast to DRO, Differential Reinforcement of Incompatible Behavior (DRI) rewards an individual for engaging in an alternative behavior that cannot physically occur at the same time as the problem behavior (e.g. sitting on your hands instead of picking at your skin). Lastly, differential reinforcement of alternative behavior rewards behavior that is not necessarily incompatible with the target behavior but serves the same function as the target behavior (e.g., providing people with a competing behavior to occupy their time instead of skin picking). All of these techniques have been reported to have some success in small studies, but none has been tested in large enough populations to provide definitive evidence of their effectiveness. Biofeedback Tentative evidence suggests that devices that provide feedback when the activity occurs can be useful. Prognosis Typically, individuals with excoriation disorder find that the disorder interferes with daily life. Hindered by shame, embarrassment, and humiliation, they may take measures to hide their disorder by not leaving home, wearing long sleeves and pants even in the heat, or covering visible damage to the skin with cosmetics and/or bandages. When untreated, excoriation disorder can last anywhere from 5 to 21 years. However, many doctors consider this disorder to be a permanent diagnosis. Excoriation has been documented as showing active from an onset in childhood and remaining active through adulthood. Epidemiology The prevalence of excoriation disorder is not well understood. Estimates of the prevalence of the condition range from 1.4 to 5.4% in the general population. One U.S. telephone survey found that 16.6% of respondents "picked their skin to the point of noticeable tissue damage" and that 1.4% would qualify as meeting the requirements of excoriation disorder. Another community survey found a rate of 5.4% had
