AN ANALYSIS OF MAINTENANCE FOLLOWING FUNCTIONAL COMMUNICATION TRAINING

The multiple and long-term effects of functional communication training relative to a common reductive procedure (time-out from positive reinforcement) were evaluated. Twelve children participated in a functional analysis of their challenging behaviors (Study 1), which implicated adult attention as a maintaining variable. The children were then matched for chronological age, mental age, and language age and assigned to two groups. One group received functional communication training as an intervention for their challenging behavior, and the second group received time-out as a contrast. Both interventions were initially successful (Study 2), but durable results were achieved only with the group that received functional communication training across different stimulus conditions (Study 3). Students whose challenging behaviors were previously reduced with time-out resumed these behaviors in the presence of naive teachers unaware of the children's intervention history. The value of teaching communicative responses to promote maintenance is discussed as it relates to the concept of functional equivalence.     

AN EVALUATION OF RESURGENCE DURING TREATMENT WITH FUNCTIONAL COMMUNICATION TRAINING

Extinction‐induced resurgence is the recurrence of previously reinforced behavior when another behavior is placed on extinction (Lieving, Hagopian, Long, & O'Connor, 2004). This phenomenon may account for some instances of treatment relapse when problem behavior recovers during extinction‐based treatments. The current study sought to determine whether resurgence of problem behavior would reliably occur with 5 participants who received treatment with FCT. Results showed that problem behavior reemerged for all but 1 participant when the communicative response was exposed to extinction or thin schedules of reinforcement. These findings suggest that resurgence may account for some instances of response recovery during treatment, and that the described procedure may be useful for the further study of resurgence and eventual prevention of this phenomenon.     

A DEMONSTRATION OF INDIVIDUAL PREFERENCE FOR NOVEL MANDS DURING FUNCTIONAL COMMUNICATION TRAINING

Preference for mand topography was evaluated for 2 individuals with developmental disabilities who exhibited problem behavior. The results of a functional analysis showed that each participant's problem behavior was maintained by social reinforcement. Participants were taught two novel mand topographies for the same functional reinforcer, and each proved to be effective in reducing problem behavior. Finally, preference for mand topography was assessed within a concurrent‐schedules design. Results indicated that functional communication training was an effective treatment, regardless of the mand used, and that each participant demonstrated a preference for one mand topography relative to the other.     

FUNCTIONAL COMMUNICATION TRAINING WITH AND WITHOUT EXTINCTION AND PUNISHMENT

Functional communication training has been reported to be a promising treatment for severe behavior problems. In this study, functional communication training alone and combined with extinction and/or punishment was evaluated for 4 clients with severe retardation, behavior problems, and communication deficits. The participants were inpatients on a hospital unit for treatment of severe behavior disorders. They received individualized interventions based on functional assessment that included reinforcement of a communication response with the same function as their destructive behavior. Results showed that for some patients, functional communication training was not sufficient to produce clinically significant reductions in destructive behavior, and the combination of training plus punishment produced the largest and most consistent reductions.     

FUNCTIONAL COMMUNICATION TRAINING TO REDUCE CHALLENGING BEHAVIOR: MAINTENANCE AND APPLICATION IN NEW SETTINGS

We evaluated the initial effectiveness, maintenance, and transferability of the results of functional communication training as an intervention for the challenging behaviors exhibited by 3 students. Assessment indicated that escape from academic demands was involved in the maintenance of the challenging behaviors. Social attention was also implicated as controlling the behavior of 1 student. The intervention involved teaching alternative assistance-seeking and attention-getting phrases to the students in an effort to replace challenging behavior with these verbal equivalents. Multiple baseline data collected across the 3 students indicated that not only did the intervention substantially reduce challenging behavior but also that these results transferred across new tasks, environments, and teachers, and were generally maintained from 18 to 24 months following the introduction of functional communication training. These results are discussed in light of recent efforts to develop effective interventions for severe challenging behavior and to understand the processes underlying transfer and maintenance of intervention effects.     

A COMPONENT ANALYSIS OF FUNCTIONAL COMMUNICATION TRAINING ACROSS THREE TOPOGRAPHIES OF SEVERE BEHAVIOR PROBLEMS

We evaluated the separate treatment components of a functional communication training program for 3 severely handicapped persons who each displayed different topographies of aberrant behavior. Following a functional analysis of maintaining conditions for inappropriate behavior (self-injury, stereotypy, aggression), each participant was trained to emit a communicative response that functioned to solicit reinforcement. For 2 participants, consequences (time-out or graduated guidance) for inappropriate behavior were also included. Treatment continued until the participants emitted the communicative response independently and no occurrences of inappropriate behavior were observed for at least two sessions. Following treatment, the separate contributions of the treatment components for communicative responding and for inappropriate behavior were evaluated with a reversal design. The results indicated that both sets of treatment components were necessary for maximal control over aberrant behavior. These results are discussed in relation to the efficiency, history, and control over reinforcement of both appropriate and inappropriate responses.     

FUNCTIONAL COMMUNICATION TRAINING USING ASSISTIVE DEVICES: RECRUITING NATURAL COMMUNITIES OF REINFORCEMENT

We evaluated the effectiveness of functional communication training (FCT) as an intervention for the problem behavior exhibited by 5 students with severe disabilities both in school and in the community. Following an assessment of the function of their problem behavior, the students were taught to use assistive communication devices in school to request the objects and activities that presumably were maintaining their behavior. Multiple baseline data collected across the students indicated that not only did the students use their devices successfully, but the intervention also reduced their problem behavior. In addition, data from community settings showed generalization to untrained community members. These results replicate other successful efforts to use FCT with individuals having limited communication skills, and demonstrate the value of teaching skills to recruit natural communities of reinforcement in order to generalize intervention effects to meaningful nontraining environments.     

EVALUATION OF THE “CONTROL OVER REINFORCEMENT” COMPONENT IN FUNCTIONAL COMMUNICATION TRAINING

The effectiveness of functional communication training (FCT) as a treatment for behavior disorders has been attributed to a number of variables, one of which is the individual's ability to exert control over the delivery of reinforcement. We evaluated this component of FCT by exposing individuals to conditions in which their behavior either did or did not affect the delivery of reinforcement. Three adults with mental retardation who engaged in self-injurious behavior (SIB) participated. Following a functional analysis of their SIB, the effects of FCT were compared to those of noncontingent reinforcement (NCR) in a multielement design. The amount of reinforcement during both conditions was equated by yoking the schedule of reinforcement during NCR sessions to that in effect during FCT sessions. Results indicated that FCT and NCR were equally effective in reducing the SIB of all participants and suggest that control over reinforcement delivery may not affect the degree to which FCT produces behavioral suppression. However, a different benefit of FCT was evident in the results: More consistent increases in the alternative response were observed during the FCT condition than during the NCR condition.     

A BRIEF FUNCTIONAL ANALYSIS OF AGGRESSIVE AND ALTERNATIVE BEHAVIOR IN AN OUTCLINIC SETTING

We conducted a brief functional analysis to identify maintaining variables for aggressive behavior and an alternative replacement response during a 90-min outpatient evaluation of 3 individuals with severe handicaps. During the initial analogue assessment, which focused on identifying maintaining contingencies for aggressive behavior, each participant displayed a substantially greater frequency of aggressive behavior during one condition than during any other. The contingency that produced the highest percentage of aggressive behavior was then presented for the occurrence of a specific alternative behavior (a mand). During this contingency reversal phase, each participant displayed a substantial reduction in aggressive behavior and a substantial increase in alternative behavior, thus providing a direct analysis of the equivalency of the contingency for maintaining either behavior.     

ESTABLISHING DISCRIMINATIVE CONTROL OF RESPONDING USING FUNCTIONAL AND ALTERNATIVE REINFORCERS DURING FUNCTIONAL COMMUNICATION TRAINING

Functional communication training (FCT) is a popular treatment for problem behaviors, but its effectiveness may be compromised when the client emits the target communication response and reinforcement is either delayed or denied. In the current investigation, we trained 2 individuals to emit different communication responses to request (a) the reinforcer for destructive behavior in a given situation (e.g., contingent attention in the attention condition of a functional analysis) and (b) an alternative reinforcer (e.g., toys in the attention condition of a functional analysis). Next, we taught the participants to request each reinforcer in the presence of a different discriminative stimulus (S^D). Then, we evaluated the effects of differential reinforcement of communication (DRC) using the functional and alternative reinforcers and correlated S^Ds, with and without extinction of destructive behavior. During all applications, DRC (in combination with S^Ds that signaled available reinforcers) rapidly reduced destructive behavior to low levels regardless of whether the functional reinforcer or an alternative reinforcer was available or whether reinforcement for destructive behavior was discontinued (i.e., extinction).     

REDUCING ESCAPE BEHAVIOR AND INCREASING TASK COMPLETION WITH FUNCTIONAL COMMUNICATION TRAINING,EXTINCTION AND RESPONSE CHAINING

The effects of functional communication training, extinction, and response chaining on 3 subjects' escape-maintained aberrant behavior were evaluated using a multielement design. Functional communication training consisted of teaching subjects a verbal response that was functionally equivalent to their aberrant behavior. Subjects initially were allowed to escape from a task contingent on the trained verbal response. In subsequent treatment phases, escape was contingent on the trained verbal response plus the completion of the specified number of steps in the task (response chaining). The number of steps was increased until a subject completed the task to obtain a break. Results showed that the treatment reduced rates of aberrant behavior and that the chaining procedure was effective in decreasing the availability of escape.     

EFFECTIVENESS OF FUNCTIONAL COMMUNICATION TRAINING WITH AND WITHOUT EXTINCTION AND PUNISHMENT: A SUMMARY OF 21 INPATIENT CASES

Functional communication training (FCT) is a frequently used treatment for reducing problem behavior exhibited by individuals with developmental disabilities. Once the operant function of problem behavior is identified by a functional analysis, the client is taught to emit an appropriate communicative response to obtain the reinforcer that is responsible for behavioral maintenance. Studies on FCT have typically used small numbers of participants, have reported primarily on clients for whom FCT was successful, and have varied with respect to their use of other treatment components. The main purposes of the present study were to evaluate the efficacy of FCT for treating severe problem behavior in a relatively large sample of individuals with mental retardation (N = 21) and to determine the contribution of extinction and punishment components to FCT treatment packages. FCT with extinction was effective in reducing problem behavior for the majority of clients and resulted in at least a 90% reduction in problem behavior in nearly half the applications. However, when demand or delay-to-reinforcement fading was added to FCT with extinction, treatment efficacy was reduced in about one half of the applications. FCT with punishment (both with and without fading) resulted in at least a 90% reduction in problem behavior for every case in which it was applied.     

EFFECTS OF EXTINCTION ALONE AND EXTINCTION PLUS FUNCTIONAL COMMUNICATION TRAINING ON COVARIATION OF PROBLEM BEHAVIORS

In this investigation, extinction (EXT) was applied alone or in combination with functional communication training (FCT) to less severe topographies of problem behavior while more severe topographies continued to be reinforced. EXT alone decreased less severe and increased more severe topographies of problem behavior (i.e., response covariation), whereas EXT with FCT reduced all topographies of problem behavior to near-zero levels.     

REDUCING BEHAVIOR PROBLEMS THROUGH FUNCTIONAL COMMUNICATION TRAINING

It is generally agreed that serious misbehavior in children should be replaced with socially appropriate behaviors, but few guidelines exist with respect to choosing replacement behaviors. We address this issue in two experiments. In Experiment 1, we developed an assessment method for identifying situations in which behavior problems, including aggression, tantrums, and self-injury, were most likely to occur. Results demonstrated that both low level of adult attention and high level of task difficulty were discriminative for misbehavior. In Experiment 2, the assessment data were used to select replacements for misbehavior. Specifically, children were taught to solicit attention or assistance or both verbally from adults. This treatment, which involvedthe differential reinforcement of functional communication, produced replicable suppression of behavior problems across four developmentally disabled children. The results were consistent with an hypothesis stating that some child behavior problems may be viewed as a nonverbal means of communication. According to this hypothesis, behavior problems and verbal communicative acts, though differing in form, may be equivalent in function. Therefore, strengtheningthe latter should weakenthe former.     

FUNCTIONAL ANALYSIS AND TREATMENT OF SELF‐INJURY IN A CAPTIVE OLIVE BABOON

Self‐injurious behavior (SIB), such as self‐biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences delivered by handlers and keepers in the maintenance of SIB in this population. The current study investigated the effects of social contact as a potentially reinforcing consequence for the SIB displayed by an olive baboon (Papio hamadryas anubis). Results indicated that the behavior was maintained by attention from humans. As treatment, reinforcement was arranged for an appropriate alternative response, resulting in increases in the appropriate alternative behavior and decreases in SIB.     

FUNCTIONAL ANALYSIS AND TREATMENT OF ELOPEMENT ACROSS TWO SCHOOL SETTINGS

The elopement of a child with Asperger syndrome was assessed using functional analyses and was treated in two school settings (classroom and resource room). Functional analyses indicated that elopement was maintained by access to attention in the resource room and obtaining a preferred activity in the classroom. Attention- and tangible-based interventions were compared in an alternating treatments design in both settings. Results validated the findings of the functional analyses. Implications for the assessment and treatment of elopement are discussed.     

COMMUNICATION SKILLS TRAINING FOR PARENTS: EXPERIMENTAL AND SOCIAL VALIDATION

Coordination of professional services on behalf of children often hinges on the involvement of informed parents. The purposes of this study were to identify and experimentally and socially validate skills required of parents for effective communication with professionals. Target skills were identified on the basis of judges' social validation ratings of (a) sample interactions between parents and professionals and (b) the behaviors comprising a resultant task analysis. Eight parents were then trained in these skills via an instructional package. Results of a multiple baseline design across subjects and grouped skill domains showed that each parent acquired the targeted skills during simulated conferences and that correct responding usually generalized to actual conferences. Independent judges validated training outcomes, and participating parents indicated satisfaction with the curriculum.
