Is Play Therapy an Evidenced-Based Intervention for Children with Autism?

As a board-certified behavior analyst (BCBA), I work with families that have a child diagnosed with an autism spectrum disorder (ASD), and periodically see an increased interest in specific interventions. Multiple families start asking me whether a specific intervention is as effective as they are led to believe. Play therapy is one of those interventions. In the past year, 10 parents asked me whether play therapy is an effective intervention. That number of parents may not seem a lot, but when I see approximately 30 families a year, that is 33% of my families questioning a specific therapy. Even though my training is with behavioral interventions – specifically applied behavior analysis – I am not one to discount non-behavioral interventions as ineffective without considering the supporting evidence. So off to the library I went!

We know autism spectrum disorders are one of the fastest growing developmental disorders in the United States, with a prevalence rate of 1 out of 68 children (CDC, 2016). This discouraging fact provides more reason to identify effective, evidence-based treatments for children with ASD. Currently, autism interventions based on behavioral theories – such as applied behavior analysis – are the gold standard since they are documented as effective. However, some researchers in the autism field (e.g., Gallo-Lopz & Rubin, 2012; Greenspan & Wieder, 2006; Ray, Sullivan, & Carlson, 2012) proposed play therapy as a potential intervention for children with ASD, since it addresses core issues of children with ASD such as social and relationship concerns. Since children with ASD have difficulty relating to others, play may be a wonderful tool for helping them move beyond self-absorption into varied, shared interactions.

The purpose of this paper is to (a) discuss what play therapy is, (b) discuss whether it is an effective intervention for children with ASD, and (c) take away points.

Play therapy involves children engaging in play activities of their choice. The play therapy environment gives children with ASD opportunities to express themselves in ways that are most comfortable. Unlike many behavioral interventions, the play therapist’s job is participating in a relationship with the child through play (Ray, Sullivan, & Carlson, 2012). One type is child-centered, a relationship-based intervention based on Axline’s (1969) early work, explaining that the client – not the therapist – was the primary agent of change. Instead of the therapist leading therapy, children are in charge of the pace, direction, and content of the therapeutic journey. In child-centered play therapy the therapist enters the world of the child and uses the relationship as an intervention, rather than training children to engage in specific behaviors that may conflict with their natural ways of being.

I conducted a comprehensive search of the literature and very little research was published on using play therapy for children with ASD. I found only five studies (Carden, 2009; Josefi & Ryan, 2004; Kenny & Winick, 2000; Mitteldorf, Hendricks, & Landreth, 2001; Salter, Beamish, & Davie, 2016). In summary, all five studies used child-centered to increase social behaviors and play interactions of children with ASD. Participants ranged from five to 11 years old. All five studies reported a small increase in social engagement and increased play interactions among the participants. Even though the results are encouraging, there are limitations. All five studies used a case study design – meaning that each study focused on one participant. Since case studies are not a strong experimental design it is difficult to generalize results to the larger community. In addition, we do not know whether the change in the participant’s behavior was due to the intervention or other extraneous variables since the intervention was not implemented with additional participants. Hence, it is difficult to say that the play therapy intervention was effective in all five studies. The participants in the five studies either were engaged in other autism interventions outside of the study or the studies themselves used it along with other interventions. Hence, we do not know the impact of play therapy specifically on behavior change since it was not an isolated intervention. Lastly, all five studies did not address social interaction with peers, and there is little information on generalization of skills learned during therapy to other situations and settings. Even with the limitations, child-centered play therapy has merit and deserves further investigation.

So what can we glean from the extant literature? For one, researchers are in the initial stages of determining whether play therapy is an effective intervention for children with autism. In order to recommend it as an evidenced based intervention, researchers need to conduct better-designed research – more participants, play therapy as a sole intervention, assessing the impact of it on behaviors over time, and stronger experimental designs – that allows us to confidently state behavior change was caused by play therapy. While the five studies did not show a discernible effectiveness of play therapy, the findings highlight the need for continued research into the potential effectiveness of it for children with ASD.

Second, the theory behind play therapy makes it suitable in addressing some of the core difficulties exhibited by children with ASD (Ray, Sullivan, & Carlson, 2012) such as limited social interactions and communication difficulties. With therapy, children have the opportunity to develop trust with the therapist and feel comfortable. Once a child feels safe, he or she may be motivated to engage socially with the play therapist, eventually generalizing his or her skills to home and school environments.

Third, a benefit of play therapy is that parents can take an active role. Parents can be included in it sessions and over time take on more of the therapist duties or conduct play therapy sessions at home. Hence, it may be a cost effective intervention while also helping parents build stronger relationship with their children.

Fourth, behavioral interventions and play therapy can supplement one another. It allows children to practice communication and social skills in a relaxed environment. Child-centered play therapy does not teach children to play, but allow children to explore their own mode of playing at their own pace while developing social skills. A benefit of this is children may engage in spontaneous imitation of the parent or the therapist playing with them.

Fifth, using child-centered play therapy as an adjunctive intervention with behavioral interventions is likely to be effective because it taps into areas of behavior – such as attachment behaviors and spontaneous play – not easily reached by behavioral interventions. If nothing else, it is likely children on the autism spectrum can benefit in some way from play therapy.

Over the years there has been growth in the research and understanding of children with ASD. As the number of children with ASD has grown, so have the number of interventions. It is vital for parents and professionals to learn about evidenced-based interventions when considering interventions for children with ASD so they are not wasting precious time and resources on ineffective interventions.

Child-centered play therapy may in the future become an evidence-based intervention, but for now it is too early to tell. More research on the efficacy of child-centered play therapy needs to be conducted. Overall, this review provides a launch pad for extending the conversation on how we can incorporate play into effective interventions for children with ASD. Since play is central to the developmental of all children, and some children with ASD have deficiencies in play, it is important to look at methods of using play in future interventions for children with ASD – either using play therapy as a stand-alone intervention or in conjunction with evidence-based behavioral interventions.
