Inflexible Adherence to Routines or Rituals
Inflexible adherence to routines or rituals refers to a need to strictly adhere to repetitive routines or patterns of behavior. This definition applies to both verbal and nonverbal types of behavior. Individuals with an inflexibility adhered to routines or rituals are usually not able to handle even minor changes in their routines, find it very difficult to transition between activities or tasks, and insist on taking the same route everyday, or even insisting on eating the same food everyday. It can also include difficulties with communication and social skills.
