Anxiety in Individuals with Autism and Intellectual Disabilities

When Maria walked up the stairs it was awful to see. She trembled, sweated, turned red and could hardly walk at all. If staff prompted her to move quickly she became visibly upset and sometimes struck out at staff. AS someone who did not talk, Maria could not tell us what the problem was, but it certainly looked like she was terrified of going up the stairs.

Anxiety is a common experience for all of us: We should all be scared of some things. Clearly anxiety and fear are highly adaptive in some situations, although sometimes anxiety becomes non-adaptive as when is it pervasive or related to non-threatening stimuli. Behavior analysis has addressed this topic many years ago. Estes and Skinner (1941) showed that stimuli that in the past have predicted aversive stimuli some to suppress on going adaptive behavior in a similar way that we freeze or slow down as we approach a scary situation.

Most of us know how to deal with anxiety independently. We behave bravely in the face of threats. We “screw up our courage” to tell the boss the bad news or make ourselves be brave and walk along the scary cliff path. For others anxiety is more severe and disabling and people often seek help through psychiatry typically using anxiolytic medication or through various mental health professions, usually through a package of cognitive behavior therapy. More severe forms of anxiety are associated with problematic behavior such as avoidance and abuse of alcohol and other anxiolytic substances. There is a very extensive research literature on treatment of anxiety with adolescents and adults in the general population.

For individuals with autism and / intellectual disabilities anxiety disorders are also common. Behavior analysis has much to offer. Dating back to the work of Wolpe, various forms of exposure therapy are often powerfully effective for many fears, phobias and trauma-related anxiety disorders. People have extended this work to individuals with autism and intellectual disabilities with considerable success. Example include exposure therapy for individuals scared of needles, dental procedures etc. Some important differences include challenging behavior that occur in the presence of stimuli that predict fear and are probably reinforced by removal of the fear-eliciting stimuli. Recent work on disruption of rituals has been an interesting development in this area. Outside of behavior analysis, researcher have been active in evaluating cognitive behavior therapy, especially with adolescents with Asperger syndrome, but such packages almost always involve some element of exposure therapy.

Behavior analysts should know about the functional assessment and analysis of anxiety and fear disorders in individuals with autism / intellectual disabilities because such problems are highly disruptive in the lives of some individuals and their family members and staff. We also have effective therapies to offer which can make a unique contribution to the lives of the people we work with.

After observing Maria’s behavior carefully we could not figure out any triggers that made the problem better or worse. We did work out a simple exposure program. We reassigned her to a downstairs room on a temporary basis.  We learned that we she calmed down with her favorite music and certain staff. After practicing this for a few weeks we gradually re-exposed her to the stairs – literally one step at a time – only progressing on to the next step when she appeared comfortable at the current step. It took a few weeks, but Maria had conquered her fear with the help of behavior analysis.
