Social Stories were devised as a tool to help individuals with ASD (autistic spectrum disorder) better understand the nuances of interpersonal communication so that they could "interact in an effective and appropriate manner". Although the prescribed format was meant for high functioning people with basic communication skills, the format was adapted substantially to suit individuals with poor communication skills and low level functioning (e.g. children who are struggling with understanding social situations or when coping with change). The evidence shows that there has been minimal improvement in social interaction skills. However, it is difficult to assess whether the concept would have been successful if it had been carried out as designed.
