``PWS Traffic Light System'' is a helpful instrument for improving self-control abilities in the area of weight regulation for people with Prader-Willi syndrome. The method assumes that the aim of assisting and caring for people with PWS is to promote each person's self-control skills in order to help them achieve the highest possible degree of independence and a personal sense of well-being. The implementation of this method is not only limited to promoting self-responsibility in the area of weight loss. It can also be transferred in a modified form to other areas of support for people with PWS that aim to increase independence and quality of life.weiterlesen
