How are play-based techniques used by speech and language therapy in autism? 

Play-based approaches are used widely across UK speech and language therapy (SLT) to support autistic children’s communication, interaction and participation. These approaches are recommended by NICE and form part of routine practice in UK health and education services. Evidence from naturalistic developmental behavioural interventions (NDBIs) shows that play creates developmentally meaningful opportunities for shared attention, symbolic play and early language, particularly when adults follow the child’s interests and embed communication targets into motivating activities. 

Understanding how play supports communication 

In guidance from NICE, social-communication interventions for autistic children should “use play-based strategies with parents, carers and teachers” to increase joint attention, engagement and reciprocal communication. These interventions emphasise sensitive responding, modelling language, building on what the child enjoys, and creating opportunities for interaction within natural play. 

The National Autistic Society highlights that autistic communication differs from person to person and that play-based SLT helps by reducing pressure, supporting processing time, using preferred interests and enabling authentic communication attempts. Working through play also helps adults adapt their communication, focus on regulation and create interaction within a safe, predictable context. 

The RCSLT notes that SLTs use play to support social communication, language, processing, participation and emotional regulation. Play is also crucial for coaching parents, teachers and early-years staff to recognise communication attempts, model language and build daily routines that support communication development. 

Evidence and impact 

Research on NDBIs shows strong links between play-based interaction and gains in joint attention, engagement and early language. Interventions such as JASPER, EMT and the Early Start Denver Model rely heavily on child-led play, modelling, shared activities and emotionally positive interaction. 

The JASPER literature demonstrates that structured play sequences can increase joint attention, symbolic play and coordinated engagement. In several trials, increased joint engagement during play predicted growth in spoken language a key mechanism for SLT work. Evidence from the JASP+EMT+SGD trial shows that embedding AAC modelling within play also increases spontaneous communication for minimally verbal children. 

The Early Start Denver Model, a play-based NDBI, has RCT support showing improvements in early language, cognition and adaptive behaviour when toddlers receive developmentally paced, play-embedded therapy. 

Across NHS services, play-based SLT is integrated into social-communication pathways. Services such as Lincolnshire Children’s Therapy Services and Nottinghamshire Healthcare’s SLT teams use play to assess interaction, joint attention, symbolic play, regulation and early communication, and then translate observations into strategies for home and school. 

How SLTs use play-based techniques in practice 

Speech and language therapists typically combine several approaches: 

1. Child-led play. Adults follow the child’s focus, join their play and create natural opportunities for communication. This increases engagement and reduces performance pressure, aligning with NICE recommendations. 

2. Modelling language within play. SLTs model single words, phrases, gestures, symbols or AAC use during motivating play activities. Modelling within shared attention is a core NDBI principle. 

3. Expanding play actions. Therapists add simple variations such as adding a character, object or pretend action to encourage symbolic play and flexible thinking, which supports early language development. 

4. Creating communication opportunities. SLTs use playful pauses, offering choices, turn-taking and predictable routines to encourage initiations, requests, comments and joint attention. 

5. Coaching parents and educators. NICE-aligned practice emphasises coaching adults to notice communication cues, reduce language load, use visual supports and build interaction into daily play and routines. 

6. Embedding AAC in play. For AAC users, play is used to practise symbol use, requesting, commenting and shared enjoyment. The RCSLT AAC guidance highlights the importance of modelling AAC within natural contexts rather than drills. 

7. Supporting regulation and participation. SLTs adapt sensory and environmental factors so that play becomes comfortable and accessible, in line with neurodiversity-affirming practice in RCSLT autism guidance. 

Challenges and considerations 

Play-based SLT must be tailored to each autistic person’s interests, sensory needs, communication profile and preferred modalities. Some autistic children may benefit more from structured routines before they can engage in shared play. Others may need explicit visual supports or AAC integrated from the start. 

Research highlights that gains in joint attention and engagement are more consistent than gains in expressive language, and carers often need ongoing coaching to maintain techniques over time. 

Play also varies culturally and individually, so SLTs must avoid imposing neurotypical expectations and instead build on each child’s natural strengths and preferences, reflecting guidance from RCSLT and NAS. 

How services can help 

UK SLT services embed play-based approaches across early years, schools and family settings. Teams such as Nottinghamshire Healthcare and Lincolnshire Children’s Therapy Services use play-based observation and modelling as part of both assessment and intervention, ensuring that communication strategies are meaningful and rooted in everyday routines. 

Takeaway 

Play-based techniques sit at the heart of UK speech and language therapy for autistic children. Supported by NICE, the RCSLT, the NAS, and trials of JASPER, EMT and ESDM, these approaches strengthen joint attention, symbolic play, communication and participation. By working through motivating, child-led play and coaching the adults around the child, SLTs help autistic children communicate in ways that feel authentic, comfortable and connected.
