How does ABA therapy compare with Floortime for toddlers with autism? 

According to the NHS and NICE, early support for autistic children should focus on relationships, communication and everyday skills, rather than any one branded programme. The National Autistic Society NAS takes a similar view, stressing person centred approaches and avoiding endorsement of specific therapies such as Applied Behaviour Analysis ABA or DIR Floortime. 

Understanding the concept 

ABA is an umbrella term for behaviour analytic approaches that break skills into small steps and use reinforcement to build communication, play and daily living skills. In early intensive programmes, children may receive many hours per week of structured or semi structured sessions, sometimes starting in the preschool years and occasionally in the toddler period. 

Floortime, also known as DIR Floortime, is a relationship based developmental approach. It focuses on following the child’s lead, building shared attention and emotional connection and supporting functional emotional development through play. Parents are usually coached to use Floortime strategies at home in frequent, short play sessions. 

The NHS describes a broad package of early help for families, including education adjustments, speech and language therapy and occupational therapy, rather than specific ABA or Floortime packages. NICE recommends social communication interventions that use play based strategies with parents and carers to increase joint attention and reciprocal communication, but does not name ABA, EIBI or Floortime. The National Autistic Society NAS similarly lists behavioural and developmental options without promoting one branded programme for all children. 

Evidence and impact 

There are currently no robust randomised or quasi experimental trials that directly compare ABA based early intensive programmes with DIR Floortime in toddlers aged 1 to 3 years. Instead, each approach has been studied separately against usual care or eclectic services. 

For ABA, a major evidence synthesis commissioned by NIHR examined early intensive ABA based interventions for autistic children, with mean intake ages typically between about two and five years. The review concluded that these programmes can lead to statistically significant improvements in cognitive ability and adaptive behaviour after around two years, compared with treatment as usual that may include speech and language therapy, occupational therapy and structured teaching. However, the authors judged the overall certainty of evidence as low or very low because most studies were small, non randomised and at high risk of bias. A linked cost effectiveness analysis in PLOS One reached similar conclusions and highlighted substantial uncertainty about value for money in real world services. 

For Floortime, a 2023 systematic review of DIR/Floortime studies published in the Iranian Journal of Nursing and Midwifery Research found that this approach was associated with improvements in functional emotional development, social-emotional functioning, communication, and parent–child relationships in young autistic children. However, the authors note that most included studies were small, often non-randomised, used variable intensity protocols, and had relatively short follow-up periods, meaning the evidence remains preliminary. 

One key randomised controlled trial by Pajareya and Nopmaneejumruslers compared routine care with routine care plus parent delivered Floortime in preschool children aged roughly two to five years. Families in the Floortime group were coached to provide several hours of play based interaction per day over three months. Children receiving Floortime showed greater gains in functional emotional development and reductions in autism severity scores than those receiving routine care alone. However, this study did not include an ABA arm, and the age range extended beyond toddlers. 

Taken together, ABA and Floortime both show promising but methodologically limited evidence. ABA studies more often report gains in cognition and adaptive behaviour, while Floortime studies emphasise emotional development and parent child interaction. Neither approach currently has strong, toddler specific, head to head evidence. 

Practical support and approaches 

For families of toddlers, many of the helpful elements from ABA and Floortime sit comfortably within the principles promoted by the NHS, NICE and the National Autistic Society NAS. These include: 

• Using simple, concrete language and giving extra processing time 

• Building predictable routines and visual supports 

• Following the toddler’s interests in play 

• Focusing on shared attention, turn taking and enjoyment 

• Involving speech and language therapy and occupational therapy as needed 

Parents who are offered an ABA based or Floortime style programme can ask how it will support these principles and how their toddler’s goals, sensory needs and preferences will be taken into account. 

Challenges and considerations 

The evidence base for both ABA and Floortime in toddlers has important limitations. Most ABA early intensive studies recruit wider preschool samples, often without separate analysis for children under three years. Many are non randomised, and social communication outcomes and family wellbeing are not always reported in detail. 

Floortime studies tend to be smaller, with shorter intervention periods and limited long term follow up. Outcome measures often focus on functional emotional development scales that are less familiar to many clinicians, and very few trials look specifically at 12 to 36 month age bands. 

Because of these uncertainties, NICE surveillance reviews have judged the evidence insufficient to recommend any branded programme such as ABA or Floortime. The NHS and the National Autistic Society NAS therefore continue to emphasise principle based, family centred support rather than endorsing specific therapies. 

How services can help 

In the UK, local NHS services, paediatric teams, child development centres and early years settings can work with families to build an early support plan. This might include: 

• Speech and language therapy focused on early communication and interaction 

• Occupational therapy for sensory and motor needs 

• Parent groups and workshops on play based strategies 

• Adjustments in nursery or childcare to support routine and communication 

Professionals may draw elements from behaviour analytic practice, relationship based models like Floortime or other developmental approaches, but NICE and the National Autistic Society NAS stress that interventions should be collaborative, respectful and tailored to each toddler and family. 

Takeaway 

For toddlers with autism, both ABA based early intensive programmes and DIR Floortime have some encouraging research, but the evidence is low to moderate in quality and there are no strong trials directly comparing them. In line with NHS and NICE guidance, the most reliable approach is to focus on early, relationship based, communication focused support that fits your toddler’s needs and your family context, rather than chasing a particular brand of therapy.
