Applied behavior analysis

Applied behavior analysis (ABA) is a procedure concerned with analyzing the principles of learning theory and systematically applying this knowledge to change behavior of social significance.[1][2] It is the applied form of behavior analysis; the other two forms are radical behaviorism (or the philosophy of the science) and the experimental analysis of behavior (or experimental research).[1]

The name "applied behavior analysis" has replaced behavior modification because the latter approach suggested attempting to change behavior without clarifying the relevant behavior-environment interactions. In contrast, ABA tries to change behavior by first assessing the functional relationship between a targeted behavior and the environment.[3] This approach often seeks to develop replacement behaviors which serve the same function as the aberrant behaviors.[3][4][5]

Methods in behavior analysis range from early intensive behavioral interventions—for example, for children with an autism spectrum disorder (ASD)[6]—to basic research on the principles governing criminal behavior. However, ABA has also been brought to bear on a wide range of areas and behavioral problems, exemplified by the following: HIV prevention,[7] conservation of natural resources,[8] education,[9] gerontology,[10] health and exercise,[11] industrial safety,[12] language acquisition,[13] littering,[14] medical procedures,[15] parenting,[16] psychotherapy, seatbelt use,[17] severe mental disorders,[18] sports,[19] substance abuse, phobias, pediatric feeding disorders, and zoo management and care of animals.[20]

Definition

ABA is an applied science devoted to developing procedures which will produce measurable changes in behavior.[1] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research,[6] but it uses principles developed by such research, in particular operant conditioning, classical conditioning and social learning theory. Behavior analysis adopts the viewpoint of radical behaviorism, treating thoughts, emotions, and other covert cognitive activity as behavior that is subject to the same rules as observable responses. This represents a shift away from methodological behaviorism, which restricts behavior-change procedures to behaviors that are observable, and was the conceptual underpinning of behavior modification.

Behavior analysts also emphasize that the science of behavior must be a natural science as opposed to a social science.[21] As such, behavior analysts focus on the observable relationship of behavior to the environment, including antecedents and consequences, without resort to "hypothetical constructs".[22]

History

The beginnings of ABA can be traced to a group of faculty and researchers at the University of Washington including Don Baer, Sidney Bijou, Bill Hopkins, Jay Birnbrauer, Ivar Lovaas, Todd Risley, James Sherman, and Montrose Wolf.[23] In the 1960s, several of this group (Baer, Hopkins, Risley, Sherman, and Wolf) joined the Department of Human Development and Family Life at the University of Kansas,[24] where they and their colleagues began to apply the principles of behavior analysis to a wide variety of human problems. In 1968 they founded the Journal of Applied Behavior Analysis, which publishes research on the behavior analysis of socially-relevant behavior.

Notable in this early group was Ole Ivar Løvaas. He developed standardized teaching interventions based on behavioral principals, and devoted nearly a half a century to groundbreaking research and practice aimed at improving the lives of children with autism and their families, even co-founding what is today the Autism Society of America.[25] In 1965, Lovaas published a series of articles that outlined his system for coding observed behaviors, described a pioneering investigation of the antecedents and consequences that maintained a problem behavior,[25] built upon these methods to develop an effective way to teach nonverbal children to speak. He also described how to use social (secondary) reinforcers, how to teach children to imitate, and what interventions (including electric shocks) may be used to reduce life-threatening self-injury and aggression.[25] In 1973, Lovaas published a long-term follow-up of his interventions and was dismayed to find that most of the subjects had reverted to their pre-intervention behaviors. He and his colleagues proposed several ways to improve outcomes such as starting intervention during the children's preschool years instead of later in childhood or adolescence, involving parents in the intervention, and implementing the intervention in the family's home rather than an institutional setting.

Over the years, "behavior analysis" gradually superseded "behavior modification"; that is, from simply trying to alter problematic behavior, behavior analysts sought to understand the function of that behavior, what antecedents promote and maintain it, and how it can be replaced by successful behavior.[5] This analysis is based on careful initial assessment of a behavior's function and a testing of methods that produce measurable behavioral changes. Applied behavior analytic methods are used in a variety of fields, such as applied animal behavior, criminology, organizational behavior management, positive behavior support,[26][27][28] and clinical behavior analysis (including behavioral medicine and such cognitive-behavior therapies as: desensitization, contingency management, acceptance and commitment therapy, dialectical behavior therapy, and habit reversal training).

Characteristics

Baer, Wolf, and Risley's 1968 article[29] is still used as the standard description of ABA.[30] It lists the following the seven characteristics of ABA.

Other proposed characteristics

In 2005, Heward et al. suggested that the following five characteristics should be added:[32]

Concepts

Behavior

Main article: Behavior

Behavior refers to the movement of some part of an organism that changes some aspect of the environment.[36] Often, the term behavior refers to a class of responses that share physical dimensions or functions, and in that case a response is a single instance of that behavior.[37] If a group of responses have the same function, this group may be called a response class. "Repertoire" refers to the various responses available to an individual; the term may refer to responses that are relevant to a particular situation, or it may refer to everything a person can do.

Operant conditioning

Main article: Operant conditioning

Operant behavior is the so-called "voluntary" behavior that is sensitive to, or controlled by its consequences. Specifically, operant conditioning refers to the three-term contingency that uses stimulus control, in particular an antecedent contingency called the discriminative stimulus (SD) that influences the strengthening or weakening of behavior through such consequences as reinforcement or punishment.[38] The term is used quite generally, from reaching for a candy bar, to turning up the heat to escape an aversive chill, to studying for an exam to get good grades.

Respondent (classical) conditioning

Respondent (classical) conditioning is based on innate stimulus-response relationships called reflexes. In his famous experiments with dogs, Pavlov usually used the salivary reflex, namely salivation (unconditioned response) following the taste of food (unconditioned stimulus). Pairing a neutral stimulus, for example a bell (conditioned stimulus) with food caused the bell to elicit salivation (conditioned response). Thus, in classical conditioning, the conditioned stimulus becomes a signal for a biologically significant consequence. Note that in respondent conditioning, unlike operant conditioning, the response does not produce a reinforcer or punisher (e.g. the dog does not get food because it salivates).

Environment

The environment is the entire constellation of stimuli in which an organism exists.[39] This includes events both inside and outside of an organism, but only real physical events are included. A stimulus is an "energy change that affects an organism through its receptor cells."[39]

A stimulus can be described:

Reinforcement

Main article: Reinforcement

Reinforcement is the key element in operant conditioning[40] and in most behavior change programs.[41] It is the process by which behavior is strengthened. If a behavior is followed closely in time by a stimulus and this results in an increase in the future frequency of that behavior, then the stimulus is a positive reinforcer. If the removal of an event serves as a reinforcer, this is termed negative reinforcement.[42] There are multiple schedules of reinforcement that affect the future probability of behavior.

Punishment

Punishment is a process by which a consequence immediately follows a behavior which decreases the future frequency of that behavior. As with reinforcement, a stimulus can be added (positive punishment) or removed (negative punishment). Broadly, there are three types of punishment: presentation of aversive stimuli (e.g., pain), response cost (removal of desirable stimuli as in monetary fines), and restriction of freedom (as in a 'time out').[43] Punishment in practice can often result in unwanted side effects.[44] Some other potential unwanted effects include resentment over being punished, attempts to escape the punishment, expression of pain and negative emotions associated with it, and recognition by the punished individual between the punishment and the person delivering it.

Extinction

Extinction is the technical term to describe the procedure of withholding/discontinuing reinforcement of a previously reinforced behavior, resulting in the decrease of that behavior.[45] The behavior is then set to be extinguished (Cooper et al.). Extinction procedures are often preferred over punishment procedures, as many punishment procedures are deemed unethical and in many states prohibited. Nonetheless, extinction procedures must be implemented with utmost care by professionals, as they are generally associated with extinction bursts. An extinction burst is the temporary increase in the frequency, intensity, and/or duration of the behavior targeted for extinction.[46] Other characteristics of an extinction burst include an extinction-produced aggression—the occurrence of an emotional response to an extinction procedure often manifested as aggression; and b) extinction-induced response variability—the occurrence of novel behaviors that did not typically occur prior to the extinction procedure. These novel behaviors are a core component of shaping procedures.

Discriminated operant and three-term contingency

In addition to a relation being made between behavior and its consequences, operant conditioning also establishes relations between antecedent conditions and behaviors. This differs from the S–R formulations (If-A-then-B), and replaces it with an AB-because-of-C formulation. In other words, the relation between a behavior (B) and its context (A) is because of consequences (C), more specifically, this relationship between AB because of C indicates that the relationship is established by prior consequences that have occurred in similar contexts.[47] This antecedent–behavior–consequence contingency is termed the three-term contingency. A behavior which occurs more frequently in the presence of an antecedent condition than in its absence is called a discriminated operant. The antecedent stimulus is called a discriminative stimulus (SD). The fact that the discriminated operant occurs only in the presence of the discriminative stimulus is an illustration of stimulus control.[48] More recently behavior analysts have been focusing on conditions that occur prior to the circumstances for the current behavior of concern that increased the likelihood of the behavior occurring or not occurring. These conditions have been referred to variously as "Setting Event", "Establishing Operations", and "Motivating Operations" by various researchers in their publications.

Verbal behavior

Main article: Verbal Behavior

B.F. Skinner's classification system of behavior analysis has been applied to treatment of a host of communication disorders.[49] Skinner's system includes:

For assessment of verbal behavior from Skinner's system see Assessment of Basic Language and Learning Skills.

Measuring behavior

When measuring behavior, there are both dimensions of behavior and quantifiable measures of behavior. In applied behavior analysis, the quantifiable measures are a derivative of the dimensions. These dimensions are repeatability, temporal extent, and temporal locus.[50]

Repeatability

Response classes occur repeatedly throughout time—i.e., how many times the behavior occurs.

Temporal extent

This dimension indicates that each instance of behavior occupies some amount of time—i.e., how long the behavior occurs.

Temporal locus

Each instance of behavior occurs at a specific point in time—i.e., when the behavior occurs.

Derivative measures

Derivative measures are unrelated to specific dimensions:

Analyzing behavior change

Experimental control

In applied behavior analysis, all experiments should include the following:[51]

Functional analysis (psychology)

History of functional analysis

Prior to the seminal article on functional analytic methodology for aberrant behaviors, behaviorists used the behavioral technology available to them at the time. Instead of treating the function of the disruptive behavior, behavioral psychologists would instead superimpose consequences to alter disruptive behaviors. For example, in the past to decrease self-injurious behavior in an individual, behaviorists may have delivered an aversive stimulus contingent on the response, or assume a reinforcer without identifying the reinforcer that would be most motivating to the client (Iwata, 1988). This type of intervention was successful to the individual, but it was not uncommon to see other variations of aberrant behavior begin to appear. When applied behavior analysts let clients choose from a wide array of reinforcers (often determined through data collection and reinforcement assessments) in the mid-1980s, reinforcement was shown to be more effective than punishment contingencies. In general, applied behavior analysis as a field favors reinforcement based interventions over aversive contingencies, but at the time the behavioral technology was not advanced enough and the individuals needing intervention had a right to an effective treatment (Van Houten et al., 1988). Nevertheless, not all behavioral therapies involved the use of aversives from the 1960s to early 1980s. Some behaviorists (for instance, B.F. Skinner) always preferred reinforcement and extinction contingencies over punishment—even when behavior modification was the dominant of practice.

In 1977, Edward Carr published a paper on potential hypotheses for the occurrence and maintenance of self-injurious behaviors. This paper laid out the initial groundwork for a functional analysis of aberrant behaviors. In the paper, Carr described five potential causes for self-injurious behaviors that included (1) positive social reinforcement contingent on the response, (2) negative reinforcement in the form of removal of an aversive stimulus contingent on the response, (3) the response produced stimuli possessed reinforcing qualities (automatic reinforcement), (4) the behavior was a byproduct of an underlying psychological condition, and (5) psychodynamic hypothesis in which the behavior was an attempt to reduce guilt. Throughout the paper, Carr cited recent research to support the first three hypotheses, and disprove the latter two hypotheses, but no formal experiment was conducted to determine the controlling variables of the problem behavior.

In 1982, Iwata and colleagues conducted the first experimental analysis of the maintaining variables for self-injurious behavior. In the paper, the researchers alternated between specific conditions to examine whether or not the behavior occurred under specific environmental conditions. Through direct manipulation of the environment, the researchers could accurately identify the controlling variables of the aberrant behavior, and provide interventions that targeted the functional relationship between the behavior and the environment. Since this seminal article was published, a wide range of research has been published in the area of functional analyses of aberrant behaviors. The methodology has since become the gold standard in assessment and treatment of aberrant behaviors.

Functional behavior assessment (FBA)

Functional assessment of behavior provides hypotheses about the relationships between specific environmental events and behaviors. Decades of research have established that both desirable and undesirable behaviors are learned and maintained through interactions with the social and physical environment. Functional behavior assessments are used to identify controlling variables for challenging behaviors as the basis for intervention efforts designed to decrease the occurrence of these behaviors.

Functions of behavior

Behavior serves two major functions for an individual: (1) to obtain desired events, or (2) to escape/avoid undesired events. Put another way, individuals engage in behavior to get something or to get out of something. When trying to identify the function of a behavior, it is often helpful to think, “What purpose is this behavior serving the individual?” Described below are the common functions of behavior.

Obtain desired events (positive reinforcement)

Obtain socially mediated events

Access to attention (positive reinforcement: social): The individual engages in the behavior to obtain attention from another person. For example, a child throws a toy because it characteristically results in mom's attention. (If this behavior results in mom looking at child and giving him lots of attention—even if she's saying "NO"—he will be more likely to engage in the same behavior in the future to get mom's attention.) Common forms of attention include, but are not limited to, hugs, kisses, reprimands, frowns, smiles, etc.

Access to tangibles (positive reinforcement: tangible/activity): The individual engages in the behavior to obtain a specific item or engage in a specific activity from another person. For example, a child hits mom because s/he wants the toy mom is holding. (If this behavior results in mom giving the child the toy, s/he will be more likely to engage in the same behavior in the future to get mom's attention.) Common forms of tangible items include, but are not limited to, food, toys, movies, video games, etc.

Obtain perceptual stimulation

Automatic positive reinforcement: The individual engages in the behavior because the response-produced stimulation possesses reinforcing characteristics. In other words, engaging in the behavior produces reinforcing stimulation unique to the specific context. For example, a child hits his/her eyes because it produces the specific stimulation of various colors and effects. Another example includes a child spinning a bowl on a table to produce the specific auditory stimulation unique to that object. Common forms of automatic stimulation include, but are not limited to, auditory stimulation, visual stimulation, endorphin release, etc.

Escape/avoid undesirable events (negative reinforcement)

Escape/avoid socially mediated events

Escape/removal of attention: The individual engages in the behavior to escape aversive socially mediated attention. Put another way, social situations that are aversive to the child are removed contingent on the behavior occurring. For example, a child hits the teacher to avoid talking in front of the class. Common forms of aversive social situations include, but are not limited to, smiles, hugs, frowns, corrections, group settings, etc.

Escape/removal of tasks or activities: The individual engages in the behavior to escape aversive tasks or demands. For example, when a child is told to take a bath he begins to cry, and his mother tells him he no longer has to take a bath. Another example includes a teacher telling a student to complete a series of math problems, to which the student flips the desk and is sent to the principal’s office. Being sent to the principals office reinforced the behavior of flipping the desk because it allowed the child to escape the aversive activity of completing math problems. Common forms of aversive demands/activities include, but are not limited to, difficult tasks, changes in routines, unpredictability, novel tasks, etc.

Escape/avoid specific stimulation

Automatic negative reinforcement: The individual engages in the behavior because it produces a decrease in aversive stimulation. Put another way, something aversive is occurring in some location on the organism's body, and engaging in the behavior decreases the level of discomfort. For example, a child bangs his head against the wall to decrease the pain experienced from a toothache. Another example includes a child scratching his arm to decrease the level of itchiness experienced from a bug bite. Common forms of aversive stimulation abated by engaging in specific behaviors include sinus pain, itching, hunger, etc.

Function versus topography

As previously stated function refers to the effect the behavior produces on the environment. The actual form of the behavior is referred to the topography. Different behaviors may serve the same function, thus describing one limitation of treating behaviors based on form alone. For example, a child may scream, hit, and cry to obtain attention from his mother. What the behavior looks like often reveals little useful information about the conditions that account for it. However, identifying the conditions that account for a behavior, suggests what conditions need to be altered to change the behavior. Therefore, assessment of function of a behavior can yield useful information with respect to intervention strategies that are likely to be effective.

Method of identifying functions of behavior

FBA methods can be classified into three types:

Indirect FBA

This method uses structured interviews, checklists, rating scales, or questionnaires to obtain information from persons who are familiar with the person exhibiting the behavior to identify possible conditions or events in the natural environment that correlate with the problem behavior. They are referred to as "indirect" because they do not involve direct observation of the behavior, but rather they solicit information based on others' recollections of the behavior. This form of assessment typically yields the least reliable information about the function of behavior, but can provide insight as to possible functions of the behavior to be tested in the future, the form of the behaviors (e.g. screaming, hitting, etc.), and environments in which the behavior typically occurs (e.g. school, home, etc.). This type of assessment should be performed as the initial step of any functional behavior assessment to gather relevant information to complete more direct assessments.

Descriptive FBA

Unlike the indirect methods of FBAs, descriptive functional behavior assessment employs direct observation of behavior. These observations occur in the environment in which the behavior naturally occurs (e.g. school, home, etc.) therefore there is no direct manipulation of the environment. The most common form of descriptive assessment involves recording the antecedents and consequences that naturally occur when the individual emits the behavior. This is referred to as ABC data collection, in which (A) represents the common antecedent, (B) represents the behavior of interest, and (C) represents the immediate consequences that occur following the behavior. ABC data collection is used to identify the naturally occurring consequences delivered in the environment in which the behavior occurs. ABC data collection can be conducted by a wide array of individuals who have received appropriate training on how to record the data. Another form of descriptive FBA is called a scatterplot. In this assessment, staff record the time and setting in which the behavior of interest occurs over a series of days. The data are plotted on a visual scale to indicate whether there are any patterns in the behavior (for example, if the behavior occurs more frequently during math instruction than it does during lunchtime). Although this assessment does not indicate the consequences maintaining the behavior, it can be used to identify some of the antecedent conditions that typically precede the behavior of interest.

Functional (experimental) analysis

A functional analysis is the most direct form of functional behavior assessment, in which specific antecedents and consequences are systematically manipulated to test their separate effects on the behavior of interest. Each manipulation of the antecedent and consequence in a particular situation is referred to a condition. In a functional analysis, conditions are typically alternated between quite rapidly independent of responding to test the different functions of behavior. When data paths are elevated above the control condition (described below) it can be said that there is a functional relation between that condition and the behavior of interest. Below, common examples of experimental conditions are described. A standard functional analysis normally has four conditions (three test conditions and one control):

Attention

In this condition, the experimenter gives the individual moderately preferred items and instructs them to go play. After that initial instruction, the experimenter pretends to act busy and ignores all bids for attention from the individual. If the individual engages in the behavior of interest, the experimenter provides the individual with attention (commonly in the form of a reprimand). Behaviors that occur more frequently in this condition can be said to be attention maintained.

Escape

In this condition, the experimenter instructs the individual that it is time to work. After the initial instruction, the experimenter delivers a series of demands that the individual is typically required to complete (e.g. math problems, cleaning up, etc.). If the individual engages in the behavior of interest, the demand is removed and the child is allowed to take a break. Behaviors that occur more frequently in this condition can be said to be escape maintained.

Alone

Normally referred to as tangible condition. In this condition, the child is left alone with a variety of items to engage with. If the child engages in the behavior of interest, no programmed consequences are delivered. Behaviors that occur more frequently in this condition can be said to be automatically maintained.

Control (play)

In this condition, the child is allowed to engage with a variety of items during the session. No demands are placed on the child throughout the duration of the session. The experimenter provides attention to the individual throughout the session on any behavior that is not the target behavior. If the target behavior occurs, the experimenter removes attention until the behavior has subsided. This session is meant to act as a control condition, meaning that the environment is enriched for the purpose of the behavior not occurring. Said another way, by meeting environmental needs for all possible functions, the individual is not likely to engage in the behavior of interest. This condition is used as a comparison to the other conditions. Any condition that is elevated to a large degree form the control condition, shows a higher degree experimental control indicating the functional relationship between the specific environmental conditions and the behavior of interest.

Conducting a functional behavior assessment

Functional behavior assessments are rarely limited to only one of the methods described above. The most common, and most preferred, method for identifying the function of behavior can be seen as a four part processes.

  1. The gathering of information via indirect and descriptive assessment.
  2. Interpretation of information from indirect and descriptive assessment and formulation of a hypothesis about the purpose of problem behavior.
  3. Testing of a hypothesis using a functional analysis.
  4. Developing intervention options based on the function of problem behavior.

Technologies discovered through ABA research

Task analysis

Task analysis is a process in which a task is analyzed into its component parts so that those parts can be taught through the use of chaining: forward chaining, backward chaining and total task presentation. Task analysis has been used in organizational behavior management, a behavior analytic approach to changing the behaviors of members of an organization (e.g., factories, offices, or hospitals).[53] Behavioral scripts often emerge from a task analysis.[54][55] Bergan conducted a task analysis of the behavioral consultation relationship[56] and Thomas Kratochwill developed a training program based on teaching Bergan's skills.[57] A similar approach was used for the development of microskills training for counselors.[58][59][60] Ivey would later call this "behaviorist" phase a very productive one[61] and the skills-based approach came to dominate counselor training during 1970–90.[62] Task analysis was also used in determining the skills needed to access a career.[63] In education, Englemann (1968) used task analysis as part of the methods to design the Direct Instruction curriculum.[64]

Chaining

Main article: Chaining

The skill to be learned is broken down into small units for easy learning. For example, a person learning to brush teeth independently may start with learning to unscrew the toothpaste cap. Once they have learned this, the next step may be squeezing the tube, etc.[65][66]

For problem behavior, chains can also be analyzed and the chain can be disrupted to prevent the problem behavior.[67] Some behavior therapies, such as dialectical behavior therapy, make extensive use of behavior chain analysis.[68]

Prompting

A prompt is a cue or assistance to encourage the desired response from an individual.[69] Prompts are often categorized into a prompt hierarchy from most intrusive to least intrusive. There is some controversy about what is considered most intrusive: physically intrusive versus hardest prompt to fade (i.e., verbal).[70] In a faultless learning approach, prompts are given in a most-to-least sequence and faded systematically to ensure the individual experiences a high level of success.[71] There may be instances in which a least-to-most prompt method is preferred. Prompts are faded systematically and as quickly as possible to avoid prompt dependency. The goal of teaching using prompts would be to fade prompts towards independence, so that no prompts are needed for the individual to perform the desired behavior.[72][73]

Types of prompts:

This is not an exhaustive list of all possible prompts. When using prompts to systematically teach a skill, not all prompts need to be used in the hierarchy; prompts are chosen based on which ones are most effective for a particular individual.

Fading

The overall goal is for an individual to eventually not need prompts. As an individual gains mastery of a skill at a particular prompt level, the prompt is faded to a less intrusive prompt. This ensures that the individual does not become overly dependent on a particular prompt when learning a new behavior or skill.

Thinning a reinforcement schedule

Thinning is often confused with fading. Fading refers to a prompt being removed, where thinning refers to the spacing of a reinforcement schedule getting larger.[74] Some support exists that a 30% decrease in reinforcement can be an efficient way to thin.[75] Schedule thinning is often an important and neglected issue in contingency management and token economy systems, especially when developed by unqualified practitioners (see professional practice of behavior analysis).[76]

Generalization

Generalization is the expansion of a student's performance ability beyond the initial conditions set for acquisition of a skill.[77] Generalization can occur across people, places, and materials used for teaching. For example, once a skill is learned in one setting, with a particular instructor, and with specific materials, the skill is taught in more general settings with more variation from the initial acquisition phase. For example, if a student has successfully mastered learning colors at the table, the teacher may take the student around the house or his school and then generalize the skill in these more natural environments with other materials. Behavior analysts have spent considerable amount of time studying factors that lead to generalization.[78]

Shaping

Main article: Shaping (psychology)

Shaping involves gradually modifying the existing behavior into the desired behavior. If the student engages with a dog by hitting it, then he or she could have their behavior shaped by reinforcing interactions in which he or she touches the dog more gently. Over many interactions, successful shaping would replace the hitting behavior with patting or other gentler behavior. Shaping is based on a behavior analyst's thorough knowledge of operant conditioning principles and extinction. Recent efforts to teach shaping have used simulated computer tasks.[79]

One teaching technique found to be effective with some students, particularly children, is the use of video modeling (the use of taped sequences as exemplars of behavior). It can be used by therapists to assist in the acquisition of both verbal and motor responses, in some cases for long chains of behavior.[80][81]

Interventions based on an FBA

Critical to behavior analytic interventions is the concept of a systematic behavioral case formulation with a functional behavioral assessment or analysis at the core.[82][83] This approach should apply a behavior analytic theory of change (see Behavioral change theories). This formulation should include a thorough functional assessment, a skills assessment, a sequential analysis (behavior chain analysis), an ecological assessment, a look at existing evidenced-based behavioral models for the problem behavior (such as Fordyce's model of chronic pain)[84] and then a treatment plan based on how environmental factors influence behavior. Some argue that behavior analytic case formulation can be improved with an assessment of rules and rule-governed behavior.[85][86][87] Some of the interventions that result from this type of conceptualization involve training specific communication skills to replace the problem behaviors as well as specific setting, antecedent, behavior, and consequence strategies.[88]

Efficacy in autism

ABA-based techniques are often used to change behaviors associated with autism, so much so that ABA itself is often mistakenly considered to be synonymous with therapy for autism.[6] ABA for autism may be limited by diagnostic severity and IQ.[89][90] The most influential and widely cited review of the literature regarding efficacy of treatments for Autism is the National Research Council's book Educating Children with Autism (2001) which concluded that ABA was the best research supported and most effective treatment for the main characteristics of Autism. Some critics{who} claimed that the NRC's report was an inside job by behavior analysts but there were no board certified behavior analysts on the panel (which did include physicians, speech pathologists, educators, psychologists, and others). Medications have not been proven to correct the core deficits of ASDs and are not the primary treatment. ABA is the primary treatment according to the American Academy of Pediatrics.[91] Recent reviews of the efficacy of ABA-based techniques in autism include:

A 2009 systematic review and meta-analysis by Spreckley and Boyd of four 2000–2007 studies (involving a total of 76 children) came to different conclusions than the aforementioned reviews.[99] Spreckley and Boyd reported that applied behavior intervention (ABI), another name for EIBI, did not significantly improve outcomes compared with standard care of preschool children with ASD in the areas of cognitive outcome, expressive language, receptive language, and adaptive behavior.[99] In a letter to the editor, however, authors of the four studies meta-analyzed claimed that Spreckley and Boyd had misinterpreted one study comparing two forms of ABI with each other as a comparison of ABI with standard care, which erroneously decreased the observed efficacy of ABI.[100] Furthermore, the four studies' authors raised the possibility that Spreckley and Boyd had excluded some other studies unnecessarily, and that including such studies could have led to a more favorable evaluation of ABI.[100] Spreckley, Boyd, and the four studies' authors did agree that large multi-site randomized trials are needed to improve the understanding of ABA's efficacy in autism.[100]

A United States District Court Judge ruled withholding ABA from children (0-21) with autism causes irreparable harm, finding Elizabeth Dudek of Florida's Agency for Healthcare Administration's position suggesting ABA was experimental was arbitrary and capricious, ordering AHCA enjoined from withholding ABA. Thereafter, CMS ordered its guidance that all states to cover ABA via Head Start and Early Head Start EPSDT programs.
