Development and Validation of an Assessment-Driven Behavioral Intervention for Primary Complex Motor Stereotypies in Young Children.

Complex motor stereotypies are rhythmic, repetitive, fixed, and non-goal directed movements (e.g., bilateral flapping/waving movements of the hands/arms). Movements typically begin in early childhood and can occur in otherwise normally developing ("primary") or autistic ("secondary") children. Stereotypies persist, occur multiple times a day, have prolonged durations, can be socially stigmatizing, and may lead to bullying and isolation. Prior behavioral treatment studies have focused on older children (ages 6-12) and report modest reductions in stereotypy (i.e., between 14% and 33%). The current study involves the functional assessment and treatment of five children with Primary Complex Motor Stereotypy using a modified awareness training procedure, differential reinforcement of other behavior, and schedule thinning in a nonconcurrent multiple baseline design. Results suggest a 99% reduction of motor stereotypy from baseline across all participants.

Resurgence of ethanol seeking following voluntary abstinence produced by nondrug differential reinforcement of other behavior.

Resurgence refers to the relapse of a target behavior following the worsening of a source of alternative reinforcement that was made available during response elimination. Most laboratory analyses of resurgence have used a combination of extinction and alternative reinforcement to reduce target behavior. In contingency-management treatments for alcohol use disorder, however, alcohol use is not placed on extinction. Instead, participants voluntarily abstain from alcohol use to access nondrug alternative reinforcers. Inasmuch, additional laboratory research on resurgence following voluntary abstinence is warranted. The present experiment evaluated resurgence of rats' ethanol seeking following voluntary abstinence produced by differential reinforcement of other behavior (DRO). Lever pressing produced ethanol reinforcers during baseline phases. During DRO phases, lever pressing continued to produce ethanol and food reinforcers were delivered according to resetting DRO schedules. Ethanol and food reinforcers were suspended during resurgence test phases to evaluate resurgence following voluntary abstinence. Lever pressing was elevated during baseline phases and occurred at near-zero rates during DRO phases. During the resurgence test phases, lever pressing increased, despite that it no longer produced ethanol. The procedure introduced here may help researchers better understand the variables that affect voluntary abstinence from ethanol seeking and resurgence following voluntary abstinence.

A comparison of fixed momentary differential reinforcement of other behavior to variable momentary differential reinforcement of other behavior to reduce challenging behavior

AbstractDifferential reinforcement of other behavior (DRO) is commonly used to reduce behavioral excesses. Momentary DRO schedules involve delivery of reinforcement contingent upon the absence of the target behavior at a given moment. Two variations of momentary DRO exist: fixed‐momentary (FM) DRO and variable‐momentary (VM) DRO. In the current study, we directly compared FM‐DRO and VM‐DRO schedules to reduce challenging behavior maintained by automatic reinforcement exhibited by four children with autism spectrum disorder. The results suggest that both the DRO schedules were equally effective to reduce challenging behavior. A social validity measure showed that most caregivers rated the VM‐DRO as a preferred schedule and noted the potential for FM‐DRO schedule to become more discriminable over time, which could reduce its effectiveness. However, most caregivers also commented that the FM‐DRO schedule was easier to implement.

Functional Analysis and Chained Schedule Treatment of Elopement in Teens with Autism Spectrum Disorder

ABSTRACT Elopement is one of the most common forms of problem behavior for individuals with autism spectrum disorder (ASD) and is associated with the greatest probability of a lethal outcome. This study evaluated the effects of a function-based treatment package on elopement for two teenage boys with ASD who eloped frequently from caregivers. Functional analyses (FA) identified the variables that evoked and maintained each teen’s elopement. Treatment involved a chained schedule comprised primarily of empirically derived differential reinforcement of other behavior (DRO), functional communication training (FCT), and extinction procedures. The treatment produced clinically significant decreases in elopement for both teens. Decreases in elopement maintained when the treatment evaluation was extended to additional contexts. The current study extends the literature on assessment and treatment of elopement and chained schedule treatments that involve both DRO and FCT.

Effects of environmental distractions on teachers' procedural integrity with three function-based treatments.

Past research has demonstrated the effectiveness of teacher-implemented, function-based treatments for problem behavior, but no studies have evaluated the impact of distractions on teachers' procedural integrity. In this proof-of-concept study, the experimenters employed a laboratory analog to examine the impact of distractions on levels of integrity when 5 teachers implemented 3 different treatments. Although integrity was similar across treatments when the setting was free of distractions, integrity declined for all teachers in the presence of student-driven distractions. In general, distractions had a greater impact on the integrity of differential negative reinforcement of alternative behavior (DNRA) compared to differential negative reinforcement of other behavior (DNRO) and noncontingent escape (NCE), particularly for the delivery of reinforcement. However, teachers tended to have lower levels of integrity when responding to problem behavior during DNRO. These findings support the potential viability of this approach for studying factors that impede procedural integrity in the classroom.

Behavioral Assessment and Treatment of Aerophagia

Aerophagia is characterized by excessive air swallowing and can have serious negative effects on one’s health. We present the assessment and treatment of a 16-year-old girl, Khloe, with developmental disabilities and aerophagia. The initial assessment indicated that aerophagia occurred primarily to access attention in a divided attention context; however, our function-based treatment did not result in a clinically significant reduction in problem behavior. We then conducted a second assessment that indicated that Khloe’s aerophagia indeed occurred primarily in a divided attention context, but that it persisted independent of social consequences. We concluded that the divided attention context served as a motivating variable for aerophagia. Our second treatment consisted of differential reinforcement of other behavior, noncontingent access to competing stimuli, and graduated exposure to contextual variables (i.e., people and divided attention) that occasioned aerophagia. The treatment was successful in reducing rates of aerophagia. We discuss implications for assessment and treatment, as well as recommendations for clinicians and students.

Effectiveness of Differential Reinforcement of Other Behaviors in Reducing Non-suicidal Self-Injurious Behaviors in Adolescents

Objective: This study aimed to investigate the effectiveness of differential reinforcement of other behaviors in reducing non-suicidal self-injury behaviors in adolescents. Methods: A single-subject A-B-A-B design was used in this study. The statistical population included male adolescents with self-injurious behaviors, the families of whom were seeking treatment for these behaviors. In total, four adolescents were recruited from a psychology clinic in Tehran, Iran, using convenience sampling. Participants were observed at 6, 8, 10, and 12 sessions at baseline phases of A1 and A2, followed by 12 intervention sessions after each baseline phase. The intervention included differential reinforcement of other behaviors. If the participants showed no self-injury behavior within a specific time duration, a reward was provided. Non-suicidal self-injury behaviors included self-harm, hair pulling, severe itching, pinching, wound manipulation, and hand biting. The frequency of these behaviors was assessed during each session. Visual analysis of graphed data, percentage of non-overlapping data, and mean percentage improvement were used for data analysis. Results: The results showed a fairly reliable effect for the intervention on reducing the target behavior, as indicated by a frequency reduction from phase A1 to B1 and A2 to B2 and by a frequency elevation by the intervention withdrawal from B1 to A2. The average percentage reduction across participants was obtained at 56%. However, a low rate of self-injury remained consistent for the participants. Conclusion: The results provided further evidence on the effectiveness of differential reinforcement of other behaviors in reducing self-injury behaviors. Although the intervention could reduce self-injury substantially, it seemed that it could not eliminate the behavior.

Functional analysis and treatment of aggression exhibited by cats toward humans during petting

Human-directed aggression is a common problem that can often result in rehoming or relinquishing the cat as well as injuries and infections for the human. Functional analyses (FAs) have been used to determine the cause of problem behavior by human and nonhuman animals, and treatments developed based on FA results have been proven effective. This study applied this methodology to assess and treat human-directed aggression exhibited by 3 cats during petting. Results suggested that aggression during petting for all 3 cats was maintained by social-negative reinforcement (escape from petting), and differential reinforcement of other behavior plus within-session stimulus fading (escape contingent on the absence of aggression following a specified number of pets that systematically increased as aggression remained low) was effective in decreasing aggression for all 3 cats. All 3 cats were available for adoption through a rescue organization during the study, and all of the cats were adopted after completing treatment.

The Effects of Signaled Delays on the Effectiveness of Differential Reinforcement of Other Behavior (DRO) Reinforcement Systems

Differential reinforcement of other behavior (DRO) is a commonly used reinforcement-based system for reducing problem behavior. DRO systems are particularly useful in that they are effective for the treatment of maladaptive behavior and can be individualized based on the needs of the learner. One possible way to enhance the effectiveness of DRO systems is the use of signaled delays. In the present study, the effectiveness of signaled and unsignaled DRO systems was compared for the treatment of stereotypical behavior in three adolescents and adults diagnosed with autism spectrum disorder (ASD). Results from this study suggested that while the unsignaled DRO condition was effective at reducing stereotypical behavior for one of three participants, the signaled DRO condition was effective for all three participants.

Increasing passive compliance to wearing a facemask in children with autism spectrum disorder.

The current study taught 6 children with autism spectrum disorder (ASD) to increase passive compliance of wearing a facemask across sequentially increasing durations of time. A changing‐criterion design embedded within a nonconcurrent multiple baseline design was used to evaluate the effectiveness of a resetting differential reinforcement of other behavior (DRO) without escape extinction procedure on passive compliance. Terminal probe sessions determined DRO fading intervals. Results showed that 2 participants acquired mastery level passive compliance (30 min) without fading during the initial baseline sessions. The remaining 4 participants acquired mastery level passive compliance following fading intervals within the DRO intervention. Participants' passive compliance generalized across 2 novel settings. This study replicates previous studies and extends empirical support for the use of DRO without escape extinction interventions for increasing passive compliance with medical devices in children with ASD.

Clinical applications of a brief experimental analysis for problem behavior: Analysis of treatment effects and durability

AbstractThe brief experimental analysis (BEA) is an empirical method for comparing multiple academic interventions in a short amount of time and predicting intervention effects in subsequent extended evaluations. This study extended the BEA literature by evaluating its utility for identifying effective interventions for decreasing problem behavior and increasing compliance for two individuals diagnosed with autism spectrum disorder and intellectual disability who engaged in escape‐maintained problem behavior. Across individuals, four treatment arrangements were compared to a baseline‐control condition: noncontingent reinforcement (NCR) with food, NCR with toys, differential reinforcement of other behaviors (DRO) with food, and DRO with toys. Using an alternating treatment embedded within a withdrawal design, conditions from the BEA associated with the lowest rates of problem behavior and the highest rates of adaptive behavior (i.e., compliance) were further evaluated during schedule thinning. For both individuals, the two most effective interventions from the BEA maintained effects during extended application and schedule thinning. These findings extend the utility of the BEA to identify durable interventions for decreasing problem behavior and increasing adaptive behavior.

The Use of Isolated and Synthesized Latency Functional Analyses in the Assessment and Treatment of Clothing Removal Exhibited by a Child with Autism

The case of a 9-year-old male with autism spectrum disorder (ASD) who presented with problem behavior in the form of high-frequency clothing removal is reported. Descriptive data indicated the behavior occurred when tasks were presented and commonly delayed task demands and resulted in staff attention. Two latency functional analyses with isolated and synthesized contingencies were completed to clarify the operant function of the behavior. Initial results of the synthesized analysis indicated clothing removal was sensitive to attention and escape. However, a subsequent functional analysis with isolated contingencies indicated that the behavior was maintained only by attention. A function-based intervention package consisting of attention extinction, response blocking, and differential reinforcement of other behavior (DRO) effectively reduced the frequency of clothing removal to near-zero levels. Results of the intervention were partially generalized to a new therapist. The use of latency functional analyses as a means to rapidly examine isolated and synthesized contingencies maintaining problem behavior is discussed as well as the effects of the treatment package on the behavior of clothing removal.

"Other" behavior and the DRO: The roles of extinction and reinforcement.

Jessel et al. (2015) provided some evidence to suggest that "other" behavior is strengthened in the differential reinforcement of other behavior (DRO). The present study is a systematic replication of the Jessel et al. procedures. The effects of DRO and extinction on target responding, target-other responding (a response with an established history of reinforcement), and nontarget-other responding emitted by children with intellectual and developmental disabilities and children with no known diagnoses were compared. Other behavior increased in at least one DRO condition for each participant, suggesting that other behavior increases when using DRO, at least initially. Under extinction, target responding and target-other responding decreased to low rates for three of the five participants; however, rates of nontarget-other responding were elevated compared to the DRO condition. These results suggest that increased rates of target-other responding and nontarget-other responding during the DRO condition may be a result of extinction-induced variability.

Adventitious reinforcement during long-duration DRO exposure.

Differential reinforcement of other behavior (DRO) is a procedure often used to decrease problem behavior, but the processes responsible for behavior reduction are not well understood. This study assessed whether adventitious reinforcement of other behavior contributes to DRO effectiveness when, relative to previous research, DRO exposure is prolonged. Two response options were presented on a computer and target responding was reinforced on a variable-ratio schedule. Response rates were then compared during DRO versus yoked variable-time or extinction probes. Across 2 experiments, DRO decreased target responding and increased other responding more than control conditions. However, increases in other responding did not usually maintain despite target responding remaining at low levels. DRO might adventitiously reinforce other responses transiently but the decreases in target behavior could not be entirely explained by adventitious reinforcement of the other response. Instead, reductions in target responding likely depend on the discriminability of the DRO contingency.

Examining the Effectiveness of a Variable Momentary Differential Reinforcement of Other Behavior Procedure on Reduction and Maintenance of Problem Behavior

To evaluate the effectiveness of variable-momentary differential reinforcement of other behavior (VM DRO) schedules in the reduction and maintenance of problem behavior. Specifically, will VM DRO be effective in reducing severe problem behavior for two children diagnosed with developmental disorders (DD)? Differential reinforcement of other behavior (DRO) has been demonstrated to be effective in reducing severe problem behavior for decades. However, recent manipulations to the schedule of delivery have led to advancements in DRO. Indicatively, VM DRO has been an effective intervention for automatically reinforced as well as social-positive maintained behavior for individuals with developmental disabilities. There is a dearth of research on variable- and fixed-momentary DRO schedules for individuals with DD; therefore, more examinations may be necessary. Two case studies of individuals who had been diagnosed with developmental disabilities were reviewed. Functional analyses were conducted and indicated that problem behavior for both participants was maintained by social-positive reinforcement. VM DRO was effective at reducing one participant’s problem behavior. Fixed interval differential reinforcement of other behavior (FI DRO) was effective at reducing the other participant’s problem behavior. Findings suggest that VM DRO may not be effective at reducing problem behavior for all individuals and that outcomes may be idiosyncratic.

The role of adventitious reinforcement during differential reinforcement of other behavior: A systematic replication

Differential reinforcement of other behavior (DRO) is commonly used to decrease problem behavior by presenting reinforcers contingent upon the absence of a target response. Although it is well demonstrated that DROs decrease response rates, the processes producing these decreases are not well understood. The present study systematically replicated previous research assessing whether adventitious reinforcement of alternative behavior contributes to the effectiveness of DRO. We presented university students with two options on a computer and reinforced target responding on a variable-ratio schedule. Next, we compared decreases in target-response rates and any increases in alternative responding during DRO schedules versus yoked variable-time schedules or extinction probes. DRO schedules resulted in the lowest target-response rate and highest alternative-response rate. These findings generally provide some support for the adventitious reinforcement of "other" behavior.
