Why do people with PWS skin pick? FAMCare project report by IPSWO
The behavior is thought to start in response to boredom, stress and anxiety or as a form of self-stimulation. It is also known that people with PWS have a high pain threshold and do not feel pain so intensely. Once commenced it is difficult for the person with PWS to cease the behavior without some form of external intervention, as they become “stuck” in the behavior.
If the underlying cause of the skin picking can be identified, especially where stress or anxiety is thought to be a contributing factor, the ideal would be to investigate and discuss what is causing the stress for the person with PWS. If the stress can be removed or decreased, the skin picking should also reduce. Remember, however, that the picking may continue as it may have built up to a repetitive behavior which will take longer to stop.
