Is ABA Therapy Harmful? Understanding the Controversy and Finding Quality Care

A major investigative article published by Bloomberg on May 1, 2026 asked a question that is becoming harder to avoid in mainstream media: Is ABA therapy - the most widely prescribed treatment for autism in the United States - actually effective? And could it cause harm?

For parents of children with autism, these questions can feel alarming, especially if your child is already in ABA therapy or you are in the middle of the authorization process. Here is what the research actually shows, what the criticisms mean, and how to evaluate the quality of care your child is receiving.

Why Is ABA Therapy Under Scrutiny Right Now?

Several converging forces are driving the current debate:

• Rapid cost growth: Medicaid spending on ABA has surged dramatically. North Carolina alone spent over $505 million on ABA services in 2025, up from just $1.9 million five years earlier - a 26,000% increase. State legislators across the country are now scrutinizing whether that spending delivers measurable outcomes.
• Autistic adult voices: Adults who received intensive ABA therapy as children - particularly older programs from the 1980s and 1990s - have spoken publicly about negative or traumatic experiences. Their accounts have reached mainstream audiences through social media and investigative journalism.
• Growing research questions: Some researchers argue that while ABA has decades of evidence behind it, much of the early research came from small, uncontrolled studies. Questions about long-term outcomes and quality of life remain areas of active study.

What Are the Specific Criticisms of ABA Therapy?

The criticisms of ABA therapy generally fall into several distinct categories - and it is important to understand them separately, because they do not all apply equally to modern ABA practice.

Criticism 1: Early ABA Was Harmful

This criticism is largely accurate and widely acknowledged within the field. Early ABA programs - particularly the Lovaas-style discrete trial training developed in the 1960s and 1970s - used aversive techniques including mild electric shock, food deprivation, and physical correction. These practices are now universally rejected and banned. The Behavior Analyst Certification Board (BACB) prohibits aversive techniques and requires practitioners to operate under an ethical code that prioritizes dignity and well-being.

Criticism 2: ABA Tries to Make Autistic People "Act Normal"

Some autistic advocates argue that certain ABA goals - suppressing stimming, requiring eye contact, demanding social performance - are aimed at making autistic people appear neurotypical rather than improving their genuine well-being. This is a legitimate critique of poorly designed programs. However, it is not inherent to ABA as a discipline. Quality ABA programs today focus on communication, independence, and safety - not behavioral compliance for its own sake.

Criticism 3: The Research Is Weaker Than Claimed

Some researchers argue that the label "gold standard" applied to ABA overstates the evidence base. This is a nuanced point. While dozens of studies support ABA's effectiveness, the field lacks the volume of large randomized controlled trials seen in some other medical interventions. Researchers continue to build that evidence base, and the field is actively working to measure long-term quality-of-life outcomes, not just short-term behavioral changes.

What Does the Research Actually Show?

The picture is more complex than either "ABA cures autism" or "ABA is harmful."

Strong evidence for core outcomes: More than 20 controlled studies have found that intensive, long-term ABA therapy improves outcomes in language development, intellectual functioning, daily living skills, and social communication for many children with autism. A comprehensive meta-analysis found meaningful improvements across multiple outcome measures for children who received ABA-based interventions.

Not universal results: ABA is effective for many children but not all. There is no one-size-fits-all outcome, and the research does not support claims that ABA will "normalize" every child with autism. Outcomes vary significantly based on the child's age at entry, intensity of services, quality of the program, and individual characteristics.

Modern ABA is fundamentally different: Today's ABA looks very different from the programs described by critics. Naturalistic Developmental Behavioral Interventions (NDBIs) - a modern form of ABA - are play-based, follow the child's interests, avoid aversive techniques, and prioritize communication and quality of life. The field has evolved substantially.

Documented harms are tied to specific practices: The cases of documented harm in the research literature are primarily associated with older techniques, use of aversive procedures, and programs with inadequate oversight. Ethical, modern ABA delivered by a credentialed BCBA should not involve punishment, coercion, or suppression of harmless behaviors.

What Does Ethical, Modern ABA Therapy Look Like?

Understanding what good ABA therapy looks like is the most practically useful thing parents can take from this debate. Not all ABA providers deliver the same quality of care, and families have the right to expect a high standard.

Signs of Quality ABA Therapy

• Credentialed supervision: Services are designed and supervised by a Board Certified Behavior Analyst (BCBA). Direct therapy is delivered by a trained Registered Behavior Technician (RBT) or similar credentialed staff.
• Individualized, meaningful goals: Your child's program is based on a thorough assessment and targets skills that matter for their daily life and independence - not a generic curriculum applied to every child.
• Active family involvement: Parents are trained as part of the program. Your input shapes goals, and you can observe sessions and ask questions freely.
• Naturalistic and play-based methods: Sessions are engaging and child-directed, not repetitive drill-and-response training.
• Data-driven progress reviews: The supervising BCBA reviews progress data regularly and adjusts goals as your child advances or needs change.
• Transparency and open access: You can observe sessions at any time, and staff can explain clearly what they are doing and why in each session.

Red Flags to Watch For

• Staff who cannot explain the purpose of a specific session or activity
• Programs focused on stopping behaviors without teaching replacement skills or communication alternatives
• High staff turnover or limited BCBA supervision hours per week
• Resistance to parent observation or involvement in goal-setting
• No regular data reviews or adjustments to the treatment plan
• Any mention of aversive techniques - these are not part of ethical modern ABA practice
• Goals that seem aimed at appearance (suppressing harmless stimming, demanding eye contact) rather than functional skill-building

Questions to Ask Before Starting ABA Therapy

Before enrolling your child with any provider, ask these questions directly:

1. What does a typical session look like for a child my child's age and profile?
2. How many hours per week will a BCBA directly supervise my child's program and observe sessions?
3. How are goals set, and how often are they reviewed and updated?
4. How do you handle behaviors you want to reduce - will you also teach a replacement behavior or communication alternative?
5. Can I observe sessions, and will you provide regular parent training?
6. What is your approach when a child is distressed or unwilling to participate in an activity?

Reputable providers will welcome these questions. Evasive or dismissive answers are themselves informative.

What Autistic Adults Want Parents to Hear

The autistic community has raised important points that parents deserve to take seriously - not to reject ABA outright, but to approach it as informed advocates for their child.

Many autistic self-advocates ask parents to consider: Is this therapy goal about my child's safety, independence, and communication? Or is it about making my child appear more neurotypical to others?

This is a legitimate and important question. The best ABA providers are asking it too. The BACB updated its ethics code in recent years to explicitly emphasize dignity, the right of clients to assent to treatment, and quality of life as primary outcomes - reflecting exactly these concerns from the autistic community.

Listening to autistic adults who describe their experiences does not mean dismissing ABA. It means using their perspective to demand better programs and ask better questions.

The Bottom Line for Parents

ABA therapy is not monolithic. There is a wide spectrum between the harmful programs critics describe from decades past and the naturalistic, family-centered programs delivered by ethical modern providers. Where your child's therapy falls on that spectrum depends almost entirely on the provider you choose.

The Bloomberg investigation and the ongoing public debate serve an important function: they push the field to be more accountable and push families to ask harder questions. That benefits everyone.

If your child is currently receiving ABA services and you have concerns, start by talking openly with the supervising BCBA. If the conversation does not satisfy you, seek a second clinical opinion. You are your child's strongest advocate.
