Effective ABA Strategies to Reduce Challenging Behaviors

Event
September 12, 2025

Challenging behaviors in individuals with autism spectrum disorder (ASD) can significantly impact their ability to learn, socialize, and participate in daily activities. Applied Behavior Analysis (ABA) therapists have developed a comprehensive arsenal of evidence-based strategies to address these behaviors effectively. With more than 20 studies establishing that intensive and long-term therapy using ABA principles improves outcomes for many children with autism, understanding these strategies is crucial for families, educators, and healthcare professionals.

Understanding the Foundation: Why Challenging Behaviors Occur

Before implementing any intervention strategy, ABA therapists recognize that all behavior serves a purpose. Applied Behavioral Analysis (ABA) is based on the idea that all behavior happens for a reason, with four basic functions that cause all behaviors. These functions include seeking attention, escaping or avoiding demands, accessing tangible items, and obtaining sensory stimulation.

Challenging behaviors are actions that interfere with a person’s ability to navigate their environment independently or safely, including behaviors such as aggression, self-injury, elopement, noncompliance, or property destruction. Understanding these underlying functions is the cornerstone of effective intervention.

The Power of Data: Success Rates in ABA Interventions

The effectiveness of ABA strategies for reducing challenging behaviors is well-documented through extensive research. Results from longitudinal studies indicate an 86% decrease in target behavior, sustaining across all topographies as dosage of treatment reduced by almost 20%. Even more encouraging, the greatest reductions occurred during the first year of treatment.

Research consistently demonstrates impressive outcomes: ABA therapy boasts an impressive success rate of over 89% in improving key developmental areas such as IQ scores, communication skills, and language abilities. Furthermore, a landmark study conducted by O. Ivar Lovass Ph.D in 1987 reported that 90% of children showed substantial improvements following intensive ABA therapy, with 47% of the treated children progressing to the point of being indistinguishable from their peers.

Core Strategy 1: Behavior Intervention Plans (BIPs)

One of the most comprehensive approaches ABA therapists use is the development of Behavior Intervention Plans (BIPs). A Behavior Intervention Plan (BIP) in Applied Behavior Analysis (ABA) is a personalized strategy designed to understand and address specific behaviors exhibited by individuals, particularly those with autism or disabilities, outlining why a behavior occurs and incorporating tailored strategies, tools, and support systems to teach alternative, more appropriate behaviors.

The development of effective BIPs follows a systematic process:

Functional Behavior Assessment (FBA)

Learning how to address challenging behaviors involves examining 3 parts of behavior: the antecedent, the behavior itself, and the consequence. This three-part model helps ABA professionals design effective behavior support strategies that are tailored to the individual.

Implementation and Monitoring

The first step in addressing challenging behaviors is to reduce their occurrence through a well-developed Behavior Intervention Plan. ABA teams gather data through observations and interviews to understand the specific needs of the individual. Once the data is analyzed, the team creates a personalized BIP with evidence-based strategies, and the plan is followed consistently by therapists, educators, and caregivers to ensure long-term success.

Core Strategy 2: Functional Communication Training (FCT)

Functional Communication Training stands out as one of the most powerful interventions in the ABA toolkit. Functional communication training (FCT) is one of the most common and effective interventions for severe behavior problems, with an extensive body of research supporting the use of Functional Communication Training (FCT) across a wide population, settings and behaviors.

How FCT Works

Functional communication training (FCT) is a differential reinforcement (DR) procedure in which an individual is taught an alternative response that results in the same class of reinforcement identified as maintaining problem behavior. Problem behavior is typically placed on extinction.

Success Factors in FCT

Due to the relative simplicity and effectiveness of FCT, parents and teachers often find this intervention highly acceptable and willingly implement it. With minimal training, parents and teachers often implement the intervention with high fidelity.

The key to successful FCT implementation lies in several critical factors:

Accurate Function Identification: A fundamental aspect, and the most important first step, of implementing FCT successfully is accurately identifying the function of the challenging behavior. By understanding the underlying purpose or function of the behavior, practitioners develop targeted interventions that teach learners to communicate effectively.
Teaching Replacement Behaviors: One of the most proactive ways to reduce challenging behaviors is to teach replacement behaviors—functional skills that serve the same purpose as the behavior being addressed. ABA teams work with individuals to teach functional communication methods, and teaching these skills empowers the individual to meet their needs in appropriate and effective ways.

Core Strategy 3: Differential Reinforcement Techniques

Differential reinforcement represents a cornerstone of behavior reduction strategies in ABA. Research in applied behavior analysis (ABA) consistently demonstrates that differential reinforcement (DR) methods are highly effective in decreasing problematic behaviors across various settings and populations. Studies have shown that techniques such as Differential Reinforcement of Alternative Behavior (DRA), Differential Reinforcement of Incompatible Behavior (DRI), and Differential Reinforcement of Other Behavior (DRO) can lead to significant reductions in challenging actions like aggression, self-injury, tantrums, and stereotyped movements.

Types of Differential Reinforcement

Differential Reinforcement of Alternative Behavior (DRA):
This strategy involves reinforcing positive, adaptive behaviors to encourage them while decreasing maladaptive behaviors. For instance, if a child typically throws a tantrum to get a toy, teaching them to ask for the toy using words or gestures can effectively replace the tantrum with more appropriate communication.

Differential Reinforcement of Incompatible Behavior (DRI):
This technique involves reinforcing behaviors that cannot occur simultaneously with the problem behavior.

Differential Reinforcement of Other Behavior (DRO):
Differential Reinforcement of Other Behavior (DRO) procedures reinforce the absence of the target behavior.

Effectiveness of Differential Reinforcement

A meta review of existing research by Wong et. al (2015) included DRI and DRA as evidenced-based interventions, providing strong support for their use in clinical practice.

Core Strategy 4: Positive Reinforcement Systems

Positive reinforcement is one of the main strategies used in ABA. When a behavior is followed by something that is valued (a reward), a person is more likely to repeat that behavior. Over time, this encourages positive behavior change.

Implementing Effective Reinforcement

Reinforcement is a cornerstone of how to address challenging behaviors effectively. ABA professionals identify what motivates the individual—whether it’s praise, preferred activities, or sensory input—and create a reinforcement system that increases desired behaviors. The reinforcement schedule is customized to the learner’s needs and evolves over time to support ongoing progress.

Core Strategy 5: Environmental Modifications and Antecedent Strategies

Prevention is often more effective than intervention after challenging behaviors occur. The key is to utilize proactive strategies that address problematic behaviors before they happen. Proactive strategies are ABA therapy techniques used to shape and change the social environment, or how your child interacts with the environment. The strategies aim to reduce the frequency of a challenging behavior or prevent it from occurring at all.

Practical Proactive Strategies

Environmental Support:
Creating Supportive Environments by changing the environment can significantly impact behavior. Calmer settings help children focus better and feel more secure. Keeping distractions to a minimum and providing a comfortable space for activities can facilitate better engagement.

Routine Establishment:
Establishing Consistent Routines through predictable daily schedules can reduce anxiety for children by clarifying what is expected of them in various situations. Consistency helps children feel secure and understand transitions better, minimizing the chances of challenging behaviors.

Priming and Preparation:
In the world of ABA, priming is setting the stage for success. Think of it as a preview or a warning. When you prime your child, you’re letting them know what to expect. The goal is to help your child become more prepared and know what to expect.

Treatment Intensity and Duration: What the Research Shows

The research clearly demonstrates that treatment intensity matters significantly. Intensive and long-term refer to programs that provide 25 to 40 hours a week of therapy for 1 to 3 years. Furthermore, some studies have shown that when ABA therapy was used for more than 20 hours a week during the first few years of life (before age 4), it produced large gains in development and even reduced the need for special services later in life.

However, research on service continuation reveals important insights: Data shows that approximately 66% of children referred for Applied Behavior Analysis (ABA) stay in services for 12 months, while less than 50% continue for 24 months. Only 28% of the children received a full dose of ABA. However, those with the lowest baseline functioning still achieved clinically significant gains after 24 months of therapy.

Addressing Specific Challenging Behaviors

Self-Injurious Behavior

Research has shown remarkable success in addressing self-injurious behaviors. Following the implementation of the DRO procedure and access to reinforcing stimuli that were believed to provide similar sensory feedback to that of the self-injurious nail biting, the results indicate that the nail biting was successfully reduced and maintained at near zero levels.

Aggression and Property Destruction

Frequency of episodes of challenging behavior, including aggression, elopement, property destruction and self-injury, were collected during studies, with all 20 participants engaging in aggression, elopement, property destruction and/or self-injury within the first three months of treatment.

The Role of Team Collaboration

Success in reducing challenging behaviors requires coordinated effort across all environments. Collaboration is a critical component of developing successful BIPs. ABAs work together with educators and parents to gather comprehensive information about the child’s behavior in various settings such as home and school. This collective effort enriches the understanding of the child’s needs and promotes a consistent approach across environments.

Individualized Treatment Approaches

A qualified and trained behavior analyst (BCBA) designs and directly oversees the program. They customize the ABA program to each learner’s skills, needs, interests, preferences and family situation. The BCBA will start by doing a detailed assessment of each person’s skills and preferences and use this to write specific treatment goals.

Data-Driven Decision Making

The BCBA and therapists measure progress by collecting data in each therapy session. Data helps them to monitor the person’s progress toward goals on an ongoing basis. This continuous monitoring ensures that interventions remain effective and can be adjusted as needed.

Long-Term Outcomes and Social Significance

The ultimate goal of these strategies extends beyond immediate behavior reduction. The findings of studies demonstrate that the applied behavior analysis program significantly improves the social, communicative, and daily life skills of institutionalized children with autism spectrum disorder. ABA interventions, delivered through structured sessions, effectively enhance emotional and social development, confirming its value as a therapeutic approach.

Research indicates broader social benefits: 50% of children graduating from treatment transitioned to a general education instructional environment, demonstrating the lasting impact of these interventions.

Evidence-Based Recognition

ABA is considered an evidence-based best practice treatment by the US Surgeon General and by the American Psychological Association. Evidence based means that ABA has passed scientific tests of its usefulness, quality, and effectiveness.

Conclusion

The strategies employed by ABA therapists to reduce challenging behaviors represent a sophisticated, evidence-based approach that has demonstrated remarkable success across decades of research. From comprehensive Behavior Intervention Plans to targeted Functional Communication Training, from differential reinforcement techniques to environmental modifications, these approaches work synergistically to create meaningful, lasting change.

The impressive statistics—86% reduction in challenging behaviors, 90% of children showing substantial improvements, and success rates exceeding 89% in key developmental areas—underscore the effectiveness of these approaches when implemented consistently and with proper professional oversight.

For families and professionals working with individuals who display challenging behaviors, these ABA strategies offer hope and concrete pathways to improvement. The key lies in individualized assessment, function-based intervention, consistent implementation across environments, and ongoing data collection to ensure continued progress.

As the field continues to evolve, these foundational strategies remain at the heart of effective behavioral intervention, providing individuals with autism and other developmental disabilities the tools they need to communicate effectively, engage appropriately with their environment, and achieve their fullest potential.
