Some kids with ASD [High-Functioning Autism] develop a resistance to (or fear of) change, that then involves being rigid in their approach to their environment. Insistence on sameness, routines and rituals begin. For example:
- Particular silverware and plates must be used or the ASD youngster refuses to eat or drink.
- Objects may be stacked or lined up in a repetitive manner.
- Certain routes must be followed to and from familiar places.
- Certain items must be placed in particular places and not moved.
Confusion about coping in a world that is overwhelming influences this behavior, so the youngster with ASD responds to this uncertainty by being in control of their immediate environment, the objects in that environment, and the people in it. Repetitive motor mannerisms may occur when some kids are excited, anxious, or worried. For others, sensory sensitivities and physical enjoyment may drive repetitive jumping, arm flapping, twiddling of fingers in front of their eyes and covering ears and eyes with their hands.
Repetitive behaviors and mannerisms in ASD children is a somewhat neglected area of research. In the past, these behaviors were associated with lower levels of functioning, because repetitive motor mannerisms are also seen in kids with intellectual disability who do not have autism. These behaviors were also thought to increase during the preschool years. There is now some evidence that repetitive motor mannerisms develop differently to insistence on sameness and these behaviors follow different paths over time.
Restricted and repetitive behaviors show different patterns of stability in autistic kids based partly on the ‘subtype’ they belong to. Young kids with low NVIQ (i.e., non verbal IQ) scores often have persistent motor mannerisms. However, these behaviors often improve in kids with higher nonverbal IQ scores. Many kids who do not have “insistence-on-sameness behaviors” at a young age acquire them as they got older, and some kids who had these behaviors sometimes loss them.
What should moms and dads do about routines, rituals and repetitive motor mannerisms?
First, ask yourself the questions: “How much of a problem is it?” and “”Who for?” The answer is often that these behaviors are a problem for the mother or father, educators and counselors rather than the youngster himself (who is quite happy to be preoccupied in these ways). Therefore, it is unlikely that the youngster will want to change his behavior. The rules of thumb when making decisions about whether or not to intervene or change routines, rituals and repetitive motor mannerisms are to ask yourself:
- Will the behavior be acceptable in 5 years time?
- Does the behavior interfere with or preclude participation in enjoyable activities and an education program?
- Does the behavior increase the likelihood of social rejection or isolation?
- Does the behavior endanger the youngster or others?
In preschoolers with ASD, adherence to non-functional routines and rituals and displaying repetitive motor mannerisms may be judged inappropriate because they fall into one or more of these categories, or may be tolerated by the family and others and are not seen as problematic.
The most successful treatments for ASD children with repetitive rituals are behavioral therapy and medication. Behavioral therapy, also known as cognitive-behavioral psychotherapy (CBT), helps children learn to change thoughts and feelings by first changing behavior. It involves gradually exposing children to their fears, with the agreement that they will not perform rituals, to help them recognize that their anxiety will eventually decrease and that no disastrous outcome will occur.
Some treatment plans involve having the youngster "bossing back" the repetitive rituals, giving it a nasty nickname, and visualizing it as something he can control. Over time, the anxiety provoked by certain unwanted stimuli in the environment and the urge to perform rituals gradually disappear. The youngster also gains confidence that he can "fight" repetitive rituals.
Repetitive rituals and routines can sometimes worsen if it's not treated in a consistent, logical, and supportive manner. So it's important to find a therapist who has training and experience in treating this issue. Just talking about the rituals and fears has not been shown to help repetitive rituals, and may actually make it worse by reinforcing the fears and prompting extra rituals. Family support and cooperation also go a long way toward helping a youngster cope with repetitive rituals.
Many children can do well with behavioral therapy alone while others will need a combination of behavioral therapy and medication. Therapy can help your youngster and family learn strategies to manage the ebb and flow of symptoms, while medication often can reduce the impulse to perform rituals.
