ESDM Therapy: How It Differs from ABA

In the field of early intervention, the Early Start Denver Model (ESDM) and Applied Behavior Analysis (ABA) are both prevalent and effective therapies. Parents and educators often seek to understand how these approaches differ to make informed decisions for the children in their care.

How ESDM is different

The ESDM is a holistic multi-disciplinary model that addresses learning goals across all areas of your child’s development. These goals include:

Traditional forms of Early Intervention

Speech Pathology and Occupational Therapy are known as traditional forms of early intervention. They are generally delivered in 30-60 min sessions weekly or fortnightly and goals are focused specifically on the areas of development related to that discipline.

While traditional early intervention is enough for some children, it has been proven in many research studies that the Early Start Denver Model produces more rapid progress for children with ASD or developmental delay, compared to attending traditional speech pathology and/or occupational therapy sessions weekly or fortnightly.

Core Learning Components in ESDM and ABA

ABC Learning (Antecedent, Behaviour, Consequence)

Both ESDM and ABA are founded on the principle of ABC learning, involving an antecedent prompting a behavior, which is then followed by a consequence. This cycle forms the foundation for behavior learning therapy in both approaches. However, the application and emphasis on each component vary significantly between the two.

The Early Start Denver Model is different to Applied Behaviour Analysis:

In most respects, the ESDM is unlike ABA. ESDM is the most naturalistic and least invasive way of teaching a child.

The key distinguishing features between these two therapy models are:

Play vs. Structure

ABA

ABA is often focused on discrete trial training whereby your child must repeat a task as decided by the therapist in order to learn that skill.

ESDM

The ESDM is play based and can be delivered in any setting eg. at home, in the car, the playground, the school room and the therapy room.  The ESDM is your child having fun during therapy, making choices and receiving high quality natural teaching interactions to stimulate your child’s desire to learn new skills.

Theory

ABA

Applies theory of learning and behaviour to children with Autism.

ESDM

Applies theory of learning and behaviour to children with Autism and considers well-being and child needs.

Structure

ABA

Structure and task oriented

ESDM

Micro structures within activities based on child interests and choice.  Learning opportunities in every interaction.

Intrinsic vs. Extrinsic Reward

ABA

ABA therapists are typically trained to offer some kind of material object as a reward, such as food, stickers, or a favourite toy. This approach is developing extrinsic motivation for your child to follow instructions. The rewards become the extrinsic object and the experience of having that object, which can lose its value over time.

We know that children who are intrinsically motivated will do better in the long term and the therapy will have longer lasting impact.

ESDM

The ESDM does not use material objects as rewards. The behaviours and skills we want to see more of are reinforced through smiles, giggles, and positive verbal and gestural reinforcement. This is called intrinsic motivation whereby your child wants to do the skill more because they want more reinforcement because it makes them feel good inside. It fulfils a sense of autonomy, competence and a relationship with others, which is known to create positive well-being.

Emotional Engagement

ABA

Generally maintains a neutral affect until positive behaviour is demonstrated.

ESDM

Always employs a positive affect, emphasising warm tone of voice, facial expressions, and body language to build relationships and attachment.

Reward

ABA

Uses external and tokenistic rewawrds to reinforce correct behaviour: stickers, lollies, favourite toy

ESDM

Uses intrinsic rewards to reinforce correct behaviour: smiles & positive affect

Managing Unwanted Behaviour

ABA

Tends to ignore unwanted behaviour.

ESDM

Focuses on understanding, responding to, and helping to manage children’s emotions and behaviours through emotion coaching and sensitivity.

Prompting

ABA

Utilises a ‘most to least’ prompting strategy.

ESDM

Least to most prompting

Key Differences Between ESDM and ABA

Rewards Strategy

ABA

Uses tangible rewards (e.g., stickers, food) as consequences for correct behaviours.

ESDM

Focuses on social rewards like praise, positive reinforcement, and giving children choices to encourage intrinsic motivation and adaptability in various contexts.

Instruction Approach

ABA

Primarily adult-led sessions.

ESDM

Child-led sessions, allowing children to make choices and follow their interests to boost motivation and enjoyment.

Emotional Engagement

ABA

Generally maintains a neutral affect until positive behaviour is demonstrated.

ESDM

Always employs a positive affect, emphasising warm tone of voice, facial expressions, and body language to build relationships and attachment.

Managing Unwanted Behaviour

ABA

Tends to ignore unwanted behaviour.

ESDM

Focuses on understanding, responding to, and helping to manage children’s emotions and behaviours through emotion coaching and sensitivity.

Prompting

ABA

Utilises a ‘most to least’ prompting strategy.

ESDM

Employs a ‘least to most’ prompting strategy, allowing children more opportunities to respond independently before increasing assistance.

HIDE THIS SECTION The ESDM Philosophy

ESDM is built on the belief that engagement in natural and interactive settings leads to better motivation, engagement, spontaneous learning, and generalisation of skills. It incorporates elements of Pivotal Response Training and builds on the foundational principles of the Denver Model. The ESDM approach is supported by contemporary research highlighting the importance of play and learning within the context of relationships.

While Speech Therapy, Occupational Therapy, ABA and ESDM have their place in early intervention and can be effective in different contexts, the choice between them depends on the unique needs and responses of each child. The ESDM’s emphasis on social rewards, emotional engagement, child-led learning, and understanding of behaviour through empathy offers a distinctive approach, particularly in encouraging independence, confidence, and positive relationships.
