Behavior management continues to be of tremendous importance to parents and professionals. Understanding the etiology of behavior in people with FXS is critical when creating proactive strategies to successfully manage that behavior. Knowing the triggers and manipulating the environment can often succeed in preventing the person with Fragile X syndrome (FXS) from engaging in problem behavior.
This became apparent recently when consulting with a family whose son engaged in self-injurious behavior (SIB), which included hitting his forehead with his fist when he was in noisy or crowded environments. The trigger was not obvious because he loved going to restaurants and looked forward to going until he got to the door. The obvious remedy was to avoid all crowded and noisy places, but how realistic is that? Not only is it unrealistic, but it is not a good way to increase independence.
Best practice would be to identify the antecedent and develop ways in which the person with FXS can be desensitized to the environment. We would call this a lesson in self-regulation. In other words, the person would learn that before he enters a noisy environment, he would put on his ear pods and play music on his iPod or wear headsets that would muffle the sound. This would teach replacement behaviors that could help him throughout his lifespan.
The other part of the discussion coming out of the behavior symposium was the emphasis on the consequence, especially when the consequence could in fact help maintain the behavior. Taking the example above, removing or avoiding loud environments could be construed as a consequence. When the person enters the noisy environment and engages in SIB by hitting his head, he is removed from the environment. This has the effect of rewarding him for hitting his head by removing him from a situation he considers aversive. I contend that it is generally preferable to teach him how to handle noisy environments via effective behavior shaping strategies rather than reacting by avoiding those environments.
This example provides a revealing contrast between proactive and reactive strategies. While both may be necessary at given times, putting more energy and emphasis on figuring out the antecedents makes more sense in the long run because it leads to a more adaptable individual who can better manage his responses to stimuli in a wider variety of settings.
The example above is not unique. After getting background information and observing a number of behaviors, there appears to be similar antecedents that relate directly to the behavioral etiology. In an attempt to make sense of the problem behaviors, I have comprised a list from 50 intake forms and clustered them into categories. The chart that follows lists a variety of behaviors most often presented during the intake. The chart clusters the behaviors and lists corresponding remedies. Although some of the behaviors occur mostly in boys, girls may also engage in variations of each behavior, though in a less direct manner (especially in the area of self-abuse).
