Applied Behavior Analysis (ABA) has long been considered the gold standard for autism interventions, with surveys showing that 36.5% of autism caregivers utilize ABA therapy, with a majority reporting positive results. However, criticisms of applied behavior analysis (ABA) from the autistic community continue to intensify and have an appreciable impact on research, practice, and conversation in stakeholder groups.
As we enter 2025, with approximately 1 in 36 children aged 8 years identified with ASD according to estimates from CDC’s ADDM Network, the need for neurodiversity-affirming practices has never been more urgent. The demand for certified ABA therapists has skyrocketed, showing a 5,852% increase from 2010 to 2021, making it essential that these professionals are equipped with practices that honor autistic dignity and autonomy.
Understanding Neurodiversity and Its Implications for ABA Practice
Defining the Neurodiversity Paradigm
The concept of neurodiversity emerged in the late 1990s as a sociopolitical movement advocating for the acceptance of neurological differences as part of natural human diversity rather than as disorders that require fixing. The neurodiversity concept challenges the traditional medical model of disability and promotes the social model, emphasizing inclusion and acceptance of individuals with conditions such as autism, ADHD, dyslexia, and other neurodevelopmental differences.
The Shift from Medical to Social Model
Chapman and Botha (2023) describe neurodivergence-informed therapy as that which “resists default normalization, is sensitive to neurodivergent perspectives, understands disablement as relational and political, and considers disability as a potential source of community and pride”. This represents a fundamental shift from viewing autism as a pathology to be corrected to recognizing it as a neurological difference to be supported and accommodated.
Key Statistical Context
Understanding the current landscape is crucial for implementing effective neurodiversity-affirming practices:
- The latest research in 2023 from the CDC shows that one in 36 children is now diagnosed with autism. This is an increase from one in 44 children two years ago
- Boys are four times more likely to be diagnosed with autism than girls
- Statistically, Autistic children are 6-7 times more likely to be victims of sexual assault
- Applied Behavior Analysis (ABA) is a widely accepted therapeutic approach for children with autism, utilized by approximately 64% of autistic individuals
Core Principles of Neurodiversity-Affirming ABA Practices
1. Centering Autistic Voices and Expertise
ABA providers aspire to increase quality of life for autistic people; thus, it is imperative for providers to listen with humility and openness to the population we serve. Autistic individuals have unparalleled expertise in their own lives and their own communities. This principle requires:
- Incorporating autistic self-advocates as consultants and trainers
- Prioritizing the perspectives of autistic adults who have received ABA
- Including autistic people in research design and implementation
2. Respecting Bodily Autonomy and Consent
Bodily autonomy means people control what happens to their bodies. Bodily autonomy means people get to make their own decisions about what happens to their bodies. All people have the right to bodily autonomy.
For ABA therapists, this means:
- As a neurodiversity-affirming practice, we use methods that allow children to exercise their right to bodily autonomy. This means that we listen to both verbal and nonverbal cues (e.g. body language). We reinforce attempts to communicate the need for personal space, breaks, sensory interventions, assistance, etc.
- Receiving permission from a child before using physical prompts, reinforces the concept of bodily autonomy by affirming that the child has a right to their body, to how their body is touched, and who touches their body
- We use hand over hand prompting as a last resort, as this is considered an intrusive intervention and we strive to create an environment where children can learn with the least restrictive supports in place
3. Moving Beyond Compliance-Based Goals
Traditional ABA has often focused on compliance and “looking normal.” The fundamental goal of ABA is compliance with the will of the person in the position of authority, which counters self-determination, undermines self-advocacy efforts, and infringes on human dignity and fundamental human rights.
Neurodiversity-affirming approaches instead focus on:
- Functional skills development rather than neurotypical appearance
- Self-advocacy and communication skills
- Emotional regulation support without suppressing natural responses
- Environmental modifications to reduce barriers
4. Respecting Stimming and Self-Regulation Behaviors
We do not force eye contact, and we do not view goals through a compliance based lense. Some of the most noticeable physical quirks of autism are certain forms of repetitive movement or vocalisation, often referred to as ‘stimming’. These are an integral adaptive mechanism by which autistic people can calm and centre themselves.
Understanding stimming as regulation rather than pathology means:
- Allowing and supporting stimming behaviors that don’t cause harm
- Teaching appropriate times and places for stimming rather than elimination
- Providing alternative sensory tools when needed
- Although his affective and bodily distress renders Seb unable to immediately exercise his autonomy in response to the GP’s questions, the point is that his repetitive, rhythmic motor movements and vocalisations are helping him re-establish a sense of bodily unity in accordance with his practical identity, which, in turn, as autistic adults have acknowledged and as a phenomenological approach to autonomy entails, makes detached reflective self-awareness possible. Viewed in this way, stimming serves to place an individual with autism in a position to exercise their cognitive capacities and thereby exercise their autonomy
Practical Implementation Strategies
Assessment and Goal Setting
- Collaborative Goal Development
- Include the autistic individual (regardless of age or communication method) in goal setting
- Prioritize goals that increase independence and quality of life
- Avoid goals focused solely on neurotypical appearance
- Strength-Based Assessment
- Clinicians are shifting their views on autism from a medical model of disability to a neurodiversity-affirming model, which embodies the idea of embracing and supporting all neurotypes from a strengths-based lens. We present the Motor Speech Intervention for Neurodiversity Affirming Practices (MIND-AP) framework for addressing speech motor issues in autistic children. MIND-AP integrates strength-based, neurodiversity affirming practices with motor speech treatment to provide connection-based, intervention for individuals dually diagnosed with autism and motor speech deficits
Environmental Modifications
- Sensory Considerations
- Assess and accommodate sensory preferences
- Provide sensory tools and breaks as needed
- Modify lighting, sound, and textures in therapy spaces
- Communication Accessibility
- Support all communication methods (AAC, typing, verbal)
- Allow processing time
- Respect communication differences
Training and Professional Development
Parent training approaches inside of ABA may benefit from being built on a foundation that is informed by the neurodiversity paradigm. Rather than first focusing parent training efforts on behaviors that need to be increased and decreased, we could consider first teaching parents that their child is a unique, precious human being, who may have a brain that is different from many others, in ways that are both challenging and exciting. Perhaps the purpose of parent training should be to help parents see the world through their child’s eyes and empower their child to thrive in a world that is in many ways a mismatch between their neurotype and the way the world is socially structured. In other words, we should start by teaching parents that our and their job is to understand their child’s unique perspective and values, and then build therapeutic learning opportunities around those unique values and perspectives.
Addressing Historical Concerns and Moving Forward
Acknowledging Past Harms
Instead, it is likely to be more effective to fully own, in public, the ethical problems of our field’s past. Practitioners in our field’s past have committed abuse (e.g., conversion therapy) and one residential school run by behavior analysts continues to use electric shock to modify the behavior of people with and without autism today (Zarcone et al., 2020). By acknowledging the abusive practices of the past and speaking out against unacceptable practices today, we can send a clear message to the autistic community that we stand for ethical and humane support for autistic people.
Building Trust with the Autistic Community
The concerns raised by the autistic community cannot, morally or ethically, be swept aside. Trust-building requires:
- Transparent communication about practices and goals
- Regular feedback collection from autistic clients and community
- Continuous education and training updates
- Collaboration with autistic-led organizations
Measuring Success in Neurodiversity-Affirming Ways
Traditional ABA metrics often focus on behavior reduction and compliance. Neurodiversity-affirming practices measure success through:
- Quality of Life Indicators
- Self-advocacy skills development
- Emotional well-being
- Social relationships (chosen, not forced)
- Independent living skills
- Client Self-Reporting
- Regular check-ins with clients about their experience
- Satisfaction surveys
- Goal preference assessments
- Functional Outcomes
- Communication effectiveness (not just verbal speech)
- Problem-solving abilities
- Self-regulation skills
- Environmental navigation
Implementation Challenges and Solutions
Common Barriers
- Funding and Insurance Requirements
- Many insurance companies still require traditional ABA metrics
- Advocacy for policy changes is ongoing
- Training Gaps
- The increasing need for ABA therapy has led to a robust workforce in the field, with over 33,633 ABA therapists currently employed in the U.S. Job growth for ABA professionals is predicted to exceed 20% by 2029, driven by the rising incidences of autism diagnosis and awareness. The ABA profession is predominantly female, with 85.6% of therapists identifying as women, reflecting gender trends in the behavioral health landscape. Moreover, the average salary for an ABA therapist is around $36,263, significantly lower than the approximately $98,000 earned by behavior analysts, illustrating a notable disparity within the field
- Resistance to Change
- Some professionals may resist shifting from familiar practices
- Family education about neurodiversity is essential
Practical Solutions
- Gradual Implementation
- Start with small changes in approach
- Build success stories to demonstrate effectiveness
- Provide ongoing support and mentorship
- Education and Training Programs
- Develop comprehensive training curricula
- Include autistic trainers and consultants
- Offer continuing education credits
- Policy Advocacy
- Work with professional organizations for standard updates
- Advocate for insurance policy changes
- Support research on neurodiversity-affirming outcomes
The Future of ABA: A Collaborative Vision
Rakshit (2022) reflects that “the neurodiversity movement is gradually changing the focus of autism-related healthcare from ‘cure’ to ‘care'” (para. 1). This shift represents not an abandonment of ABA principles but their evolution toward more ethical, respectful, and effective practices.
Key Elements of This Evolution
- Participatory Research and Practice
- Overall, this genetic heterogeneity mirrors the phenotypic diversity of autistic individuals and provides a helpful bridge between biomedical and neurodiversity perspectives. We propose that participative and multidisciplinary research should use this information to understand better the assessment, treatments, and accommodations that individuals with autism and families need
- Intersectional Understanding
- Recognition that autism intersects with other identities
- Culturally responsive practices
- Attention to multiple marginalized identities
- Systemic Change
- Advocacy for policy reform
- Environmental and social barrier removal
- Community-wide accessibility improvements
Conclusion: Embracing Change for Better Outcomes
The evolution toward neurodiversity-affirming ABA practices represents both a professional and ethical imperative. This article summarizes some of the key criticisms that autistic advocates raise concerning ABA, discusses the social model of disability and the neurodiversity paradigm, and proposes practical guidance to help the field of ABA integrate neurodiversity and thereby evolve our research and practice. By openly acknowledging the criticisms against ABA and recognizing how we can do better as a field, we believe we can take practical steps towards a profession and a society that more fully embraces inclusion.
For ABA therapists, this shift requires:
- Continuous Learning: Stay updated on neurodiversity research and autistic community feedback
- Self-Reflection: Examine your own biases and assumptions about autism
- Collaborative Practice: Work with autistic individuals as partners, not subjects
- Advocacy: Support policy and practice changes that promote dignity and autonomy
The future of autism support lies not in eliminating autistic traits but in creating a world where autistic people can thrive as their authentic selves. By embracing neurodiversity-affirming practices, ABA therapists can be part of this transformative change, ensuring that their work truly serves the best interests of the autistic individuals and families they support.
