Understanding ABA: Evidence-Based, Compassionate Support

What Is Applied Behaviour Analysis (ABA)?

Applied Behaviour Analysis (ABA) is a scientific discipline concerned with understanding behaviour and the environmental factors that influence it. In autism services, ABA principles are used to teach skills and address barriers to participation in everyday life. Services may focus on communication, independence, learning, or other goals that are meaningful to the individual and their family.

ABA is one of the most widely recognised approaches to supporting autistic individuals, but it is also a subject of considerable debate. While research supports its use for developing certain skills, some autistic adults have described negative experiences with services they received as children. Those experiences deserve to be heard and taken seriously.

At TriPoint Autism & Literacy Education Services (TALES), we endorse evidence-based practices informed by ABA, particularly contemporary approaches that emphasise compassionate, trauma-informed care. However, ABA is not a single curriculum or teaching method. Providers can take very different approaches under the same label.

Endorsing ABA does not mean endorsing every practice associated with it. Interventions should have a clear purpose and provide meaningful benefit to the person receiving them. Families should understand what a provider actually does, rather than relying on the label alone.

Why Is ABA Controversial?

Some of the criticism directed at ABA reflects legitimate concerns about the field’s history and the experiences of people who have received services.

Historically, certain programmes placed a heavy emphasis on compliance and reducing behaviours considered undesirable. In some cases, the priority was helping autistic individuals appear more typical, rather than teaching skills that would improve their quality of life. Autistic adults have described experiences in which their preferences were disregarded or they were expected to comply with demands regardless of how they felt.

There are also concerns about interventions that target harmless autistic characteristics. Stimming, differences in eye contact, and other forms of self-expression should not automatically be treated as problems requiring intervention.

These criticisms should not be dismissed as misunderstandings of ABA. Research examining autistic adults’ recollections of childhood ABA has documented reports of harmful experiences and highlighted the need to better incorporate autistic perspectives into the delivery of services (McGill & Robinson, 2021).

At the same time, ABA is not a static discipline. Its practices and ethical expectations continue to be examined, including through growing discussion of neurodiversity-affirming approaches (Mathur et al., 2024). There is an important difference between acknowledging harmful practices and assuming that every application of ABA is harmful.

The field has a responsibility to learn from its history. That includes being willing to reconsider established practices when they do not serve the needs or interests of the individuals receiving support.

What Should Contemporary ABA Look Like?

The purpose of ABA should be to improve an individual’s quality of life

1. Goals Should Be Meaningful

Intervention goals should address skills that have practical value to the individual. Communication, self-advocacy, independence, and participation in everyday activities are examples of areas where support may be beneficial.

A behaviour should not become a treatment target simply because it looks different from what is typically expected. For example, there is no inherent reason to discourage harmless stimming or require eye contact during conversations. The important question is whether a particular skill will make a meaningful difference in that person’s life. If a goal is primarily intended just to make someone appear less autistic, it deserves serious scrutiny.

2. Autonomy and Assent Must Be Respected

Autistic individuals must have opportunities to make choices and communicate their preferences about the services they receive. This includes the ability to indicate when they do not want to participate in an activity. Continuing to place demands on someone who is communicating distress or withdrawal raises serious ethical concerns. Compliance should never be mistaken for meaningful participation.

These considerations are particularly important when working with individuals who communicate without spoken language. The absence of speech does not mean the absence of preferences, opinions, or the ability to express refusal.

3. Care Must Be Compassionate and Trauma-Informed

Distress is information. 

When an individual becomes upset, withdraws, or attempts to avoid an activity, practitioners should consider why that response is occurring. The appropriate next step may be to change the activity, reduce demands, provide a break, or reconsider the intervention altogether.

Trauma-informed care requires practitioners to consider how an individual’s experiences may affect their response to intervention. Sensory preferences, previous experiences, and the demands of a particular setting can all influence whether someone feels comfortable participating.

4. Behaviour Must Be Understood in Context

Behaviour is influenced by the environment. Communication difficulties, sensory demands, changes in routine, and expectations that exceed an individual’s current skills can all contribute to challenges with participation.

When a behaviour presents a concern, the first step should be to understand what may be contributing to it. Trying to reduce the behaviour without considering its purpose overlooks important considerations.

Consider a student who regularly leaves a classroom activity. Rather than immediately treating this as non-compliance, a practitioner might examine whether the activity is too demanding, whether the student has an effective way to request a break, or whether the classroom environment is creating sensory difficulties.

Sometimes teaching a new skill is appropriate. In other situations, the environment needs to change. Often, both are necessary.

5. Collaboration Matters

ABA practitioners should recognise that they are not the only professionals who can contribute to an individual’s development. Depending on the person’s needs, collaboration with educators, speech-language pathologists, occupational therapists, and other qualified professionals may be important.

Families should also have an active role in decisions about services. Their knowledge of the individual, including their preferences and experiences outside of therapy, can help inform intervention planning.

Importantly, autistic individuals should also have a voice in decisions that affect them. The way that voice is expressed will differ from person to person, but it should never be overlooked simply because someone communicates differently.

Is ABA Appropriate for My Child?

People have different learning profiles and support needs. Some individuals benefit from ABA services, while others may find that educational, occupational therapy, speech-language, or other supports are more appropriate. In some cases, several approaches may be helpful.

Families considering ABA should feel comfortable asking questions about a provider’s philosophy and practices. Some useful questions include:

• How are treatment goals selected? Will they address skills that are meaningful to my child?
• How do you respond when my child communicates that they do not want to participate?
• What sorts of behaviours are typically targeted for intervention?
• How do you account for sensory preferences and environmental factors?
• How will you determine whether the services are making a meaningful difference?
• How are families and other professionals involved in planning?

A provider should be able to explain why an intervention is being recommended and what evidence supports its use. Families should also be able to raise concerns without feeling that they are challenging the provider’s authority.

Finding Evidence-Based Autism Support

Families navigating autism services encounter a great deal of information, including programmes promoted with claims that exceed the available evidence. Evidence-based practice helps families and professionals evaluate these recommendations by considering research, professional expertise, and the individual needs of the person receiving services.

At TALES, we help families and educators navigate these decisions through consultation grounded in current research and the individual needs of the person receiving support. Our goal is to help people make informed choices about services and identify practices that are meaningful, appropriate, and evidence-based.
