How does ABA therapy compare with play based interventions for autistic adolescents? 

Guidance from the NHS and NICE says support for autistic children and teenagers should focus on social communication, behaviour, mental health and participation, using psychosocial and social communication interventions rather than any single branded programme. The National Autistic Society NAS takes a similar line, highlighting play based and peer mediated approaches alongside other strategies, without recommending Applied Behaviour Analysis ABA as a standard adolescent treatment. 

Understanding the concept 

ABA is a behaviour based framework that uses structured teaching, reinforcement and careful analysis of what happens before and after behaviour to help autistic people learn new skills and reduce behaviours that interfere with life. In adolescence, ABA informed work often focuses on behaviour that challenges, daily living skills, study skills and sometimes social skills training. 

Play based or relationship based interventions for adolescents are usually group or peer focused rather than floor play with adults. Examples include LEGO based therapy, social skills groups, peer mediated programmes and interest based clubs. These aim to build confidence, social understanding and friendships through structured activities and guided interaction. 

The NHS describes practical ways to support communication and daily life, such as using clear language, visual supports and predictable routines, and suggests asking about local groups and activities. NICE recommends social communication interventions that use play based strategies and, for school age children, peer mediation to increase joint attention, engagement and reciprocal communication. The NAS highlights autistic communication differences and suggests providing structured chances to practise communication in low pressure settings. 

Evidence and impact 

Direct randomised trials that compare ABA programmes with play based interventions specifically in autistic adolescents are very rare. Most of what we know comes from separate studies of social skills and play based groups on one side, and behaviour analytic or behaviourally structured programmes on the other. 

For play based and peer mediated work, evidence is moderate and growing. A large UK school trial of LEGO based therapy for autistic pupils aged 7 to 15 found that group LEGO sessions led by trained school staff produced small improvements in social skills compared with usual support, although effects were modest and less clear at one year follow up Wang et al., 2023. An NIHR report on the same programme concluded that LEGO based therapy is feasible, acceptable and may offer small social and emotional benefits as part of wider support. 

Meta analyses of social skills group programmes, which often include role play, games and peer interaction, show larger effects. One review of social skills training for autistic children and adolescents by Soares et al., (2020) reported a substantial overall improvement in social skills compared with control conditions, suggesting that structured group interventions can meaningfully support social behaviour and participation in this age range  A separate review in PubMed focused on autistic adolescents found that many social skills group trials report benefits, but also noted gaps in fidelity and outcome reporting. 

ABA related evidence for adolescents tends to be less about branded programmes and more about techniques. Many social skills curricula for teenagers use behavioural methods such as modelling, rehearsal, feedback and reinforcement, even if they are not called ABA. The same meta analysis that supports social skills groups can therefore be seen as indirect evidence for behaviourally designed, group based interventions in adolescents. 

There is also a small body of work on peer mediated interventions, where classmates are coached to support autistic peers in play and social interaction. One study that compared a peer mediated programme with an early intensive behavioural intervention model by Zhang et al., 2022 found greater gains in social communication and reduced autistic symptoms in the peer mediated group, although the sample spanned older children and younger adolescents and was not UK based. This again points to the value of peer and play based work rather than a clear advantage for intensive ABA in social domains. 

Overall, the evidence suggests that play based, peer mediated and social skills group approaches can improve social skills and sometimes friendships for autistic adolescents, with small to moderate effects. ABA based work in this age group is more often focused on behaviour and specific skill acquisition, and is less frequently studied as a comprehensive adolescent programme. 

Practical support and approaches 

In day to day life, the differences between ABA and play based approaches often matter less than whether support follows the principles described by the NHS, NICE and the NAS. These include: 

• Seeing behaviour as communication and looking for triggers such as anxiety or sensory overload 

• Providing structured, interest based social opportunities, for example clubs, gaming groups or LEGO groups 

• Using visual supports, clear rules and agreed signals to help with conversation and group activities 

• Supporting peers to understand autism and to include autistic classmates 

Families can ask schools whether social groups or peer programmes are available, and how behaviour support is provided. It is reasonable to ask whether behavioural techniques are being used in a way that is collaborative, transparent and focused on the young person’s own goals. 

Challenges and considerations 

The evidence base for both ABA and play based interventions in adolescents has important limitations. Many studies mix children and teenagers, so it is hard to know how well findings apply to older age groups. Sample sizes are often small, measures vary and follow up is usually short. Very few trials focus directly on wellbeing, loneliness or the quality of friendships. 

Guidance from NICE explicitly notes that evidence for branded programmes, including ABA, is not strong enough to recommend them as standard packages, and instead focuses on social communication interventions, play based strategies and function based behaviour support. The NHS also advises against relying on any one treatment and encourages families to look at overall support. 

The NAS stresses that interventions should aim to reduce loneliness and improve quality of life, not simply make autistic behaviour appear more typical. This is particularly important in adolescence, when masking and social pressure can take a toll on mental health. 

How services can help 

In the UK, adolescent support is shared between education, health and sometimes social care. Schools can provide reasonable adjustments, social groups and peer support schemes in line with NHS and NICE guidance. Specialist teams, such as community paediatrics or child and adolescent mental health services, may offer help with behaviour, anxiety and social communication. 

The NAS offers information on social skills groups, leisure activities and peer support, as well as advice for parents on helping teenagers find like minded friends and safe spaces to pursue their interests. 

Takeaway 

For autistic adolescents, both ABA techniques and play based or relationship focused interventions can contribute to better social skills and participation, but current evidence is stronger and more UK specific for play based, peer mediated and social skills group programmes than for intensive ABA packages. In line with NHS and NICE, the most important question is not whether an intervention is labelled ABA or play based, but whether it is respectful, collaborative and focused on the young person’s own goals, friendships and wellbeing.
