The Functional Analytic Approach to Behavior Modification for Kids on the Autism Spectrum

A “functional analytic approach” to developing effective behavioral modification in children and teens with ASD utilizes a process known as “functional behavioral assessment.”

Functional behavioral assessment involves employing a variety of strategies (e.g., child-centered planning, treatment team meetings, systematic interviews, direct observations, etc.) to formulate hypotheses about why a child behaves the way she does.

In order to accomplish a functional behavioral assessment, several assumptions about behavior must be regarded as valid:

• Behavior has communicative value. Though it is generally accepted that all behavior has communicative value, it is important to remember that children with ASD generally do not have a behavioral intent to disrupt classroom settings, but instead problematic behaviors may arise from other needs (e.g., self-protection in stressful situations). Although children with the disorder typically have excellent language skills, their ability to use communication effectively in a social context may be limited. Inappropriate behavior may be the only available communicative response to difficult situations until other options are learned.

• Behavior is context related. All children demonstrate some level of variability in behavior across different settings. This is just as true for children on the autism spectrum. In fact, understanding how the environment impacts a child is one of the chief outcomes of a functional behavioral assessment. This information has particular value for preventive methods or to set the stage for teaching alternative skills. Effective behavioral support is contingent on understanding the child, the context in which he operates, and the reason(s) for behavior.

• Behavior is functional. Behavior serves a specific purpose(s). For children with the disorder, these functions may be expressed in highly idiosyncratic and often complex verbal ways.

Though there is some disagreement about the best way to conduct a comprehensive functional behavioral assessment, most clinicians are in agreement about the key outcomes of such an assessment. They are:

identification of the consequences that maintain behavior (i.e., once a behavior starts, what keeps it going over time?)
description of situations most commonly associated with the occurrence of problematic behavior
clear and unambiguous description of the problematic behavior(s)

A functional behavioral assessment should provide information that:

guides the development of supports that are logically connected
increases understanding of the child
describes the physical and social setting(s) in which the behavior occurs
describes the problem behavior itself

Once an understanding of problem behaviors is achieved, it is helpful to come up with a behavioral modification plan. A good behavioral modification plan includes focus on:

expanding beyond consequence strategies (e.g., time outs)
preventing the occurrence of problem behavior
teaching socially acceptable alternatives to problem behavior (especially alternatives that serve the same purpose as the problem behavior and therefore are more likely to be adopted by the child)

Next, the clinician should use a comprehensive format for outlining multi-component supports that addresses the following:

Antecedent/setting event strategies
Alternative skills training
Consequence strategies
Long-term prevention

Let’s look at each of these areas:

1. Antecedent/setting event strategy: The primary goals of this strategy are to prevent or reduce the likelihood of problem behavior and to set the stage for learning more adaptive skills over time. For example, many children on the spectrum have difficulty with noisy, crowded environments. Therefore, the newly arrived middle school student who becomes physically aggressive in the hallway during passing periods may need an accommodation of leaving class a minute or two early to avoid the congestion which provokes this behavior. Over time, the student may learn to negotiate the hallways simply by being more accustomed to the situation, or by being given specific instruction or support.

Key issues to address when discussing this strategy are:

What can be done to eliminate the problem (i.e., the antecedent condition)?
What can be done to modify the situation if it can’t be eliminated entirely?
Will the antecedent strategy need to be permanent, or is it a temporary "fix" which allows the student to increase skills needed to manage the situation in the future?

The importance of using antecedent strategies should not be underestimated. Kids on the spectrum often have to manage a great amount of personal stress. Striking a balance of short and long term accommodations through manipulating antecedents to problem behavior is often critical in setting the stage for later skill development.

2. Alternative Skills Training: The primary purpose of this strategy is to teach skills that replace problem behavior by serving the same purpose as the challenging behavior. For example, a student with the disorder may have trouble "entering" into a kickball game by asking to play and instead simply inserts himself into the game, thereby offending the other players and risking exclusion. Instead, the youngster can be coached on how and when to ask to enter into the game.

Here is a particularly useful framework for guiding efforts towards teaching alternative skills by examining the following three categories:

A. Equivalence training

B. General skills training

C. Self-regulation training

A. Equivalence training requires support persons to ask the following sequential questions:

How will alternative skills be taught?
What alternative skill(s) will be taught which serves the same function as the problem behavior?
What is the function of the problem behavior?

B. General “skills training” requires asking the following sequential questions:

How will alternative skills be taught?
What other academic, social, or communication skills will be taught that will prevent the problem behavior from occurring?
What skill deficits are contributing to the problem behavior?

C. Self-regulation training requires asking the following sequential questions:

How will skills be taught?
What events appear to be contributing to the child's anger or frustration in reference to the problem behavior?
What self-control skills will be taught to help the child deal with difficult/frustrating situations?

One particularly relevant means to teach alternative skills is through the use of self-management strategies. Self-management is a procedure in which autistic children are taught to discriminate their own target behavior and record the occurrence or absence of that target behavior. Self-management is a particularly useful technique to assist children to achieve greater levels of independent or even inter-dependent functioning across many settings and situations.

By learning self-management techniques, children can become more self-directed and less dependent on continuous supervision and control. Instead of teaching situation specific behaviors, self-management teaches a more general skill that can be applied in an unlimited number of settings.

Self-management strategies have particular relevance and immediate utility for children on the autism spectrum. The basic steps for teaching self-management are:

clearly define the target behavior
identify child reinforcers
design or choose a self-management method or recording device
teach the child to use the self-management device
teach self-management independence

It is also important for teachers to monitor their own behavior when working with "special needs" students. Each time a teacher reprimands a child for misbehavior, an opportunity to reframe the moment in terms of the child's need to develop alternative skills through a means such as self-management training may be lost.

3. Consequence strategies: Though consequences have traditionally been framed in terms of how they reduce problem behavior as a form of discipline, reframing consequences in terms of “reinforcement for achieving alternative behaviors” should be the focus for ASD kids. One way to reframe the use of consequences is to develop them as “planned responses to instructional situations.” This shifting of the use of consequences does not mean that negative consequences should be eliminated (especially in moments of crisis), but that multiple negative consequences are likely to heighten anxiety levels for the child and compete with teaching alternative skills.

4. Long-term prevention: In the presence of immediate behavioral concerns, it may be difficult to come up with a long-term approach to a child's educational program. However, it is critical that plans for supporting a child over the long-term be outlined from the beginning. Many supports with the most relevance for kids on the spectrum (e.g., specific accommodations, peer supports, social skills, self-management strategies, etc.) must be viewed as procedures that are developed progressively as the youngster moves through school. These are not “crisis management” techniques, but the very strategies that can decrease crisis situations from developing.

Those involved with the child will need to collaborate on a behavioral modification plan that is clear and easily implemented. Once developed, the plan will need to be monitored across settings. Inconsistencies in expectations and behaviors will only serve to heighten the challenges demonstrated by the child.
