When delivering ABA therapy, it’s important to listen, reflect, and reconsider approaches to service delivery to ensure the most effective treatments for those within the autistic and neurodivergent communities and beyond.

In this study by Allen, Mellon, Syed, Johnson, and Bernal, they reflected on an ongoing trend in the field of ABA that focuses on how to best listen and collaborate with autistic clients and their stakeholders. In the report, the researchers provided an overview of this trend as well as suggestions for best practice. At Beacon, our goal is to respect neurodiversity while working with each child and their family to identify and teach new skills that increase independence and autonomy.

We’re passionate about delivering ABA services that are supported by evidence-based peer-review research to young children with autism.

A characteristic of autism is repetitive behavior, and this often manifests itself in children by them lining up and ordering items such as toy cars, blocks, animals, or any household items. For some children, if an arrangement of items is disrupted, this results in problem behavior.

In this study, Anderson and Kenaston-Manasseh identified if the function of the participants problem behavior was environmental restoration, such as fixing an item out of sequence. In identifying the function, this demonstrated that children with this profile could be taught to request the items to be restored to their original locations without exhibiting problem behavior.

We’re passionate about delivering ABA services that are supported by evidence-based peer-review research to young children with autism.

Teaching children with autism to request items that they want is a critically important skill. In this study by Chezan, Bauer, Drasgow, Garcia, and Warman, they researched if constant time delay prompting and the delivery of rewards could be used to teach children this skill.
This study included 3 children with autism, ranging in age from 3-6 years who had limited communication skills, either vocally or through gestures. Each child was given a preference assessment to identify a highly preferred object that the child was taught to request, such as bubbles, a laptop, and a tablet. The researchers then taught the children individualized requests which included pointing, reaching, or leading. Next, when the child showed interest in the highly preferred item, they were prompted to physically request the item and then were given the item as a reward for 30 seconds. Results found that all 3 children learned to request the preferred item after training. This training also highlighted the importance of determining the child’s interest prior to teaching. It’s important to ensure that the child is interested in the item before beginning instruction.

A study by Pálsdóttir, Magnússon, and Sveinbjörnsdóttir conducted an experimental analysis of academic task refusal for a child with a developmental disability. Task refusal was analyzed in two experimental analyses. The first experimental analysis was to see if the child’s behavior was maintained by negative reinforcement, and the second was to see if the behavior exhibited by the child was the result of transitioning between academic tasks differing in preference. They discovered that task refusal did not occur in the demand condition of the functional analysis, indicating that the behavior was not maintained by escape from demands. Furthermore, task refusal occurred solely in the second experimental analysis when transitioning from a task that was highly preferred to one that was not preferred. It was determined that it wasn’t the less preferred academic task itself that was aversive, but rather transitioning from a preferred academic task to one that was not.

Often, sessions with your child’s therapist involve a cycle of learning trials followed by a break with a reinforcer. When children display challenging behaviors when learning tasks are presented, we often conclude that this behavior functions to avoid or escape the task. This study suggests that this sequence has multiple components: ending a task, transitioning to a reinforcer, ending a reinforcer, and possibly transitioning to a new task that is less preferrable than the preceding task. This study highlights the importance of considering all the possible reasons for challenging behavior. A careful assessment of any task refusal helps your Beacon clinical team provide a learning environment that will be successful for your child. The goal is keeping your child happy, relaxed, and engaged throughout sessions!

Behavioral treatment involves teaching the child an adaptive behavior to replace their challenging behavior. The ABA approach to treatment starts with assessing why a child is engaging in challenging behavior. In other words, a Beacon therapist wants to identify what a child is achieving by using challenging behaviors.

For example, if a child cannot yet ask for juice, they may repeatedly hit the refrigerator and cry until someone notices and offers them juice. Behavioral treatment involves teaching the child an adaptive behavior that can replace the challenging behavior. In this example, the behavioral therapist might teach the child to give a caregiver a picture of juice instead of crying and hitting.
In this study by Nuhu, Muething, Gillespie, Mevers, and Scheithauer, therapists coached parents on how to implement functional analyses and individualized function-based treatment packages to help alleviate challenging behavior. Forty-one families of children and young adults with neurodevelopmental disorders participated. Most clients (75.6%) met all admission treatment goals and parents reported significant decreases in frequency and severity of challenging behaviors at discharge. The results of the study suggest this parent-mediated treatment model is a viable option to treating moderate challenging behavior in children and young adults with intellectual and developmental disorders. While behavioral treatment is often conducted by BCBAs and BTs, parent involvement can result in positive outcomes that will maintain over time.

As a provider of services to young children with Autism, we’re passionate about delivering developmental, behavioral, and treatment services that are supported by evidence-based peer-reviewed research.
Identifying how someone feels and why they feel that way is an important social skill. These skills are considered “Theory of Mind” or “Perspective Taking” skills. Many children with autism have difficulties answering these questions. In this study by Persicke, Najdowski, and Tarbox, children with autism were taught how to predict emotions and infer why they felt this way. Every child who participated in the study was able to communicate in full sentences prior to the training.
As an example, the children in the study were given the following scenario: “Sara loves Halloween and loves to eat Skittles. After trick-or-treating at two houses, Sara did not get any Skittles.” The children were then asked the following: “If she doesn’t get Skittles, how will Sara feel” and ”Why does she feel this way?” (answer: Sad, because she wanted Skittles and didn’t get any). Training included providing multiple examples of correct answers, modeling, prompting and reinforcement. All the participants learned how to predict emotions as well as their causes and were able to utilize these skills in new situations.

Many parents and caregivers would like their children to be better “listeners” and follow requests without protest and refusals. In this study by Baida, Azizi, and Jessel, they investigated if an evidence-based strategy could increase the likelihood of instruction following.

Five children, ranging in age from 2-8 years old, participated in the research, with each child in the study having developmental disabilities, such as Autism and ADHD. The researchers opted to use a high-probability request sequence, which is also referred to as behavioral momentum. Low probability and high probability requests were identified for each participant. Low probability requests were those that the child was less likely to do, such as giving up something they were enjoying (“give me the iPad”) or something that was challenging, such as identifying an object’s color or reading a word. High probability requests were those that the child did without refusals, such as, “give me a high five” or “stand up.” The children who followed each instruction without protest or refusal received a reward. The study found that when a high probability request was immediately followed with a low probability request (“give me a high five, give me the iPad”), the participants were far more likely to do them compared to if they were just asked to do the low probability request. The study also assessed which method the participants and caregivers preferred, and it was discovered that the high probability request sequence was the favorite.

It’s possible that if you do something easy and get a reward, it increases the likelihood that you’ll follow the next instruction, even if it’s more challenging. It’s similar for us as adults when we do easier tasks first before tackling the bigger or more complex tasks. So, if you find yourself needing to ask your child to do something challenging, consider having them do 1-3 easy tasks first.

A major barrier that families and caregivers face is the potential to misunderstand the technical terminology that behavior analysis professionals use when trying to effectively communicate their valuable expertise.

In this study by Marshall, Weiss, and Critchfield, they evaluated the effect that technical terms have during parent training. Seventeen parents of individuals with disabilities were taught to implement discrete trial teaching via individualized instructions that contained high or low percentages of jargon. The jargon that was utilized was individually determined for each participant based on a pre-evaluation. It was discovered that parents who encountered more jargon benefitted significantly less from the training, and the jargon damaged the professional-stakeholder relationship in several ways. These findings support the idea that technical terminology has a negative impact on the effective sharing of evidence-based practices. Professionals should limit jargon whenever possible and discuss with parents and caregivers which technical terms (such as “reinforcer” or “stimulus”) are understood at the outset of services.

At Beacon, we recognize the importance of having constructive and collaborative discussions with families and stakeholders to provide the best services for children with Autism. Skills instruction and coaching must be easy to understand and implement. Be sure to ask your BCBA or behavior therapist to explain any terminology that is unfamiliar to you.

As a provider of services to young children with Autism, Beacon uses compassionate interventions and state-of-the-art services to improve and support the development of children.

Many children with Autism Spectrum Disorder (ASD) have restrictive eating patterns, which is why it’s important that we teach them to eat a variety of healthy foods. Identifying successful methods that don’t involve restrictive procedures, such as not removing a new food, is a demonstration of using compassionate interventions.

In this study by Gover, Hanley, Ruppel, Landa, and Marcus, it was discovered that rewarding a child for eating small bites of food could be successful when using an individualized approach and providing frequent choice making opportunities. Standard feeding programs can be unpleasant for the child (and caregivers), so this type of intervention can be more reinforcing, enhancing effectiveness.

When your child is expressing challenging behavior, the goal is to replace that behavior with communication skills that meet the same purpose. For example, a child who wants their parent’s attention may scream or hit because that “works” to get their attention. By teaching the child to ask for attention vocally or by handing over a picture, screaming and hitting should decrease.

As a part of this process, parents may be asked to ignore challenging behavior and only react to appropriate attempts to communicate. This article by Lloveras and McKeown caution that we should be careful in how we interpret “ignoring.” Ignoring challenging behavior shouldn’t mean not providing care to the child or standing by when unsafe behavior is occurring. When ignoring challenging behavior is recommended, it is important to ask your Beacon BCBA, “what specifically should I do?”. It might be that just limiting highly emotional responses to your child such as “WHAT DID YOU DO?” is what is necessary while continuing to provide calm care and attention. During parent training, work with your Beacon BCBA to determine how best to limit attention while being responsive to all attempts to communicate.

For parents and caregivers of children with autism, pica, the ingestion of non-food items, can be an especially dangerous behavior. Sources (CDC, 2019) report that while pica only occurs in about 4% of preschool children without disabilities, it occurs in 14% of autistic preschool aged children without intellectual disabilities and in 28% of those with autism and intellectual disabilities. While there are many different treatments for pica, prevention is the most important. This article by Thomas and O’Connor demonstrates the successful use of a safety checklist as a tool to remind caregivers to remove unsafe items that could be ingested.

If your child engages in pica, it’s important to speak to your Beacon BCBA to identify what items are most likely to be ingested, as well as the settings and activities that may trigger the behavior. Identifying the function or the “why” of the behavior is important, as some children ingest items because of the way they taste while others may do so to get your attention. Different functions require different strategies to treat the behavior. In this study, it’s suggested that if you and your BCBA develop a safety checklist, you’ll be less likely to leave unsafe items accessible to your child.

For some children with Autism Spectrum Disorder (ASD), it can be a struggle to know when they are feeling happy or sad. Communication challenges lead to children that can’t verbally report their feelings, which can add to parents’ frustration. In this study done by Ramey, Healy and McEnaney, they found that for children with ASD, happiness and unhappiness could be best identified by unique behaviors that they engaged in during enjoyable and unenjoyable conditions. For example, if the child flaps their hands and jumps when playing with bubbles, those behaviors may be their indicators of happiness. In these conditions, they also found that the children were not able to accurately self-report their feelings.

It’s important to understand what contributes to a child’s happiness. This study shows that for children with ASD, we may need to look for unique things that they do as signs of happiness. For Beacon parents and caregivers, this requires working closely with your BCBA to identify and measure these behaviors. While many preschools use emojis, emotional thermometers, or other visuals to identify emotions; children with autism may need explicit instruction to learn how to express these feelings and answer these questions.

Providing clients with a choice of behavioral intervention is an important component of administering compassionate, trauma-informed care. In this study by Huntington and Schwartz, it was found that participants with Autism/ADHD all had clear preferences for a specific intervention package, and that the intervention package was successful in reducing target behaviors and in increasing on-task behavior.

There may be more than one treatment option for a particular behavior. If that is the case, your BCBA could ask you to choose the intervention that is preferred. When working with younger clients, choice can be inferred from assent, defined as willing participation, or the absence of challenging behavior when an intervention is applied.

Beacon’s Clinical Services department is constantly reviewing current publications to identify state-of-the-art services. This month focused on Mckeown, Vollmer, Cameron, Kinsella, and Shaibani’s (2022) research report that detailed the impact of considering the needs of the whole client – including the input of the client’s family as well as other professionals.

In their report, they recognized the importance of when working with clients, especially those that are children, always considering the possibility that they are experiencing pain, which may factor into their clinical profile.

Best practice involves collaborating with medical personnel and the client’s family to investigate if pain plays a role in the causes of challenging behavior. As a compassionate caregiver, Beacon’s BCBAs will consider the impact of your child’s communication challenges, especially regarding the possibility of your child experiencing pain. By defining and measuring behaviors, your BCBA plays an essential role in identifying signs of pain that your child may be unable to communicate vocally.

An early and comprehensive response to pain by caregivers enhances your child’s health and happiness. If you’d like more information, ask your BCBA.
