Evidence-Based Practice for Children with Autism

Evidence-Based Practice for Children with Autism

Supporting children with autism spectrum disorder (ASD) requires individualized and effective intervention strategies. It is very important for families, teachers, administrators, and school-based support personnel to be knowledgeable about evidence-based approaches to adequately address the needs of students with autism and to help minimize the gap between research and practice. Although the resources for determining best practices in autism are more extensive and accessible than in previous years, school professionals face the challenge of being able to accurately identify these evidence-based strategies and then duplicate them in the classroom and other educational settings

The rapid growth of the scientific literature on ASD has also made it difficult for practitioners to stay up-to-date with research findings. Unfortunately, many proponents of ASD treatments make claims of cure or recovery, but provide little scientific evidence of effectiveness. These interventions appear in books and on websites that describe them as “cutting-edge therapies” for autism. Consequently, school-based personnel and families need to have a reliable source for identifying practices that have been shown, through scientific research, to be effective with children and youth with ASD. Evidence-based research provides a starting point for determining what interventions are most likely to be effective in achieving the desired outcomes for an individual.

Developing and implementing effective interventions and treatment for students with autism requires that they be evidence-based and supported by science. All interventions and treatments should be based on sound theoretical constructs, robust methodologies, and empirical studies of effectiveness. An evidence-based practice can be defined as a strategy, intervention, treatment, or teaching program that has met rigorous peer review and other standards and has a history of producing consistent positive results when experimentally tested and published in peer-reviewed professional journals. It excludes evidence that is supported by anecdotal reports, case studies, and publication in non-refereed journals, magazines, internet, and other media outlets.

Systematic Research Reviews

Systematic research reviews play an important role in summarizing and synthesizing the knowledge base for determining what interventions are most likely to be effective in achieving the desired outcomes for children and youth with ASD. There are two major resources available to school professionals that provide a listing, along with systematic reviews, of evidence-based interventions and practices for students with ASD: the National Autism Center’s (NAC; 2015) second phase of the National Standards Project (NSP-2), which reviewed research studies to identify established interventions for individuals with ASD, and the National Professional Development Center on Autism Spectrum Disorders (NPDC on ASD, 2015; Wong et al., 2014), which also analyzed numerous research studies and identified evidence-based practices for students with autism. Although both reviews were conducted independently, their findings are very similar and reflect a convergence across these two data sources. According to the NAC and NPDC, the following are evidence-based interventions/practices for ASD:

* Behavioral Interventions: These interventions are based on behavioral principles and are designed to reduce problem behavior and teach functional alternative behaviors.

* Cognitive Behavioral Intervention: Cognitive behavioral interventions are designed to change negative or unrealistic thought patterns and behaviors with the goal of positively influencing emotions and life functioning.

* Modeling: This intervention relies on an adult or peer providing a demonstration (live and video) of a target behavior to the person learning a new skill, so that person can then imitate the model.

* Naturalistic Interventions: These interventions primarily involve child-directed interactions to teach real-life skills (communication, interpersonal, and play skills) in natural environments. Examples include incidental teaching, milieu teaching, and embedded teaching.

* Parent-Implemented Intervention: Parents provide individualized intervention to their child to improve/increase a wide variety of skills such as communication, play, or self-help, and/or to reduce challenging behavior. Parent training can take many forms, including individual training, group training, support groups, and training manuals.

* Pivotal Response Training (PRT): PRT is a naturalistic intervention model that targets pivotal areas of a child's development, such as motivation, responsivity to multiple cues, self-management, and social initiations.

* Peer-Mediated Instruction: Teachers/service providers systematically teach typically developing peers to interact with and/or help children and youth with ASD to acquire new behavior, communication, and social skills. Common names include peer networks, circle of friends, and peer-initiation training.

* Scripting: This intervention involves developing a verbal and/or written script about a specific skill or situation which serves as a model for the child with ASD.

* Self-Management: Self-management strategies involve teaching individuals with ASD to evaluate and record the occurrence/nonoccurrence of a target behavior and secure reinforcement. The objective is to be aware of and regulate their own behavior so they will require little or no assistance from adults.

* Social Narratives: These interventions identify a target behavior and involve a written description of the situation under which specific behaviors are expected to occur. The most well-known story-based intervention is Social Stories?.

* Social Skills Training: Social skills training involves group or individual instruction designed to teach learners with ASD ways to appropriately interact with peers, adults, and other individuals.

* Visual Support: Any visual display that supports the learner engaging in a desired behavior or skills independent of prompts. Examples of visual supports include pictures, written words, schedules, maps, labels, organization systems, scripts, and timelines.

Systematic reviews synthesize the results of multiple studies and provide school professionals with summaries of the best available research evidence to help guide decision-making and support intervention practice. It must be stated, however, that these ratings are not intended as an endorsement or a recommendation as to whether or not a specific intervention is suitable for a particular child with ASD. Because no two individuals are alike, no one program exists that will meet the needs of every person with autism. Additionally, children with autism learn differently than typical peers or children with other types of developmental disabilities. 

The success of the intervention depends on the interaction between the age of the child, his or her developmental level and individual characteristics, strength of the intervention, and competency of the professional. Each child is different and what works for one may not work for another. Research findings are only one component of evidence-based practice to consider when selecting interventions. The selection of a specific intervention should be based on goals developed from a comprehensive developmental assessment as well as professional judgment and the values and preferences of parents, caregivers, and the individual with ASD.

That's all well and good as long as the pharmaceutical companies aren't funding the studies.

I'm an 'autism parent'. Children with autism - my son (14) high functioning/Asperger's- will need a complex cocktail of these approaches. However, nothing will work well if the setting the child is in does not follow recommendations, or has their own view on what is best.? eg: SELF MANAGEMENT/VISUALS : "He has a timetable, and there's a clock on the wall, so he should know when to go to lessons" (I provided a phone with alarms set for lesson times, and he still misses some - and the staff who prefer to get him, don't always!)?? This, I hasten to add, is a specialist setting, independent, and paid by our County Council. He is already on his 8th change of setting - nothing really fits - a child who is not 'good enough' to be in a specialist Asperger setting (and that might be many miles from home, so he wouldn't want to go there) and not 'bad enough' to be in a 'specialist school for SEN'.?? SOCIAL SKILLS TRAINING - no set 'programme' written down - mostly done through a few ball games based around 'tag' (not wise!) and board games. (Hmmm!)?? SELF MANAGEMENT -? w h a t ??!!?? This is tricky. There are neurotypical adults who can't self-manage. My son, as an example, bright though he is, 'forgets' he is hungry or needs a drink - but then will only accept a minimal number of foods and drinks onto his 'conveyor belt'. I have to remind him that he needs some protein that day, or needs to drink more water, as lemonade is not the best to stay healthy.? He will stop a piece of writing half way through a sentence, having been advised to write 'about 100 words' (200 he would consider far too much to write.? Any kind of 'TARGETS', he's not interested in. Even a day out has to have some real intrinsic value to him before he will deign to come with us. Targets in his school setting, he ignores - he goes from day to day, not too bothered if he misses classes ('his fault' or 'teachers' fault') --- then will have a few moments' deep concern that he isn't learning enough! It isn't just the current setting. One (mainstream) had him leave virtually the moment he got a Statement of Special Needs; one (mainstream with an autism base) said he was so aggressive, they didn't even believe he had autism (!); one (also mainstream with a base) understood little about autism- they repeatedly put him in a 'quiet room', despite my warnings - he was afraid to go upstairs or downstairs in our own house because he was afraid of the empty space between, then they wondered why he got even more angry and demonstrative when they shut him in an empty room. On one occasion, FOUR members of staff were holding him 'spreadeagled' to try to move him into the other room. At the time, he was still quite small and thin - I could literally pick him up and carry him under one arm! In the UK, we have had Statements changed to Education, Health and Care Plans (EHCPs) - It has taken TWO YEARS to get my son's EHCP into something like an acceptable and useful document - but will the setting follow what it says? Health don't want anything put into it unless they have agreed to it beforehand, so two drafts of the EHCP have been sent to me with nothing in the Health section- despite my son having been on medication for about 7 years and seeing a psychiatrist for that time too, every four to six months. This IS now in his Plan, but only because I insisted that in the February (that became April...slow systems) review that Psych, Ed Psych and Autism specialist were involved in new report writing.? Even THEN, last week, I received the 'final version' of the EHCP - still showing (crossed through) the parts they intended to remove or change. This was after I had got them to send me a copy electronically, that I would go through and remove all the crossings out and check the wording. When I called the office, they asked if I was happy for the document to stand. i told them I was happy only with the copy I sent them, with nothing crossed out, because that was the actual final document, not what they sent me. My Local Authority in March, I believe, put a stop to new applications for EHCPs until the end of June, because they had to catch up with the Plans they had in hand! (Holding back, potentially, necessary recognition of needs in many children.) The systems do not work The staff don't 'get it' There is too little funding The children can be ever-changing, so the 'goal posts' for their needs keep shifting - which means that as the system and staff can't really catch up and cope with the changing needs, the children will suffer in the long, long, long run. It's great to have all sorts of theories, and I do appreciate your writings here, but getting these theories into practice is quite another thing. I suspect that the rise in recognised autistic behaviours began (though for most of the time without 'labels') with the industrial revolution: people moving away from their traditional homes and lifestyles. I am not advocating a return to the 'old times', but when sons learned a job from their fathers, and daughters followed and learned from their mothers, everyone knew everyone (along with their foibles), and the weaknesses and strengths of individuals were known by the community, there would probably have been some advantages for the autistic child growing up - without the 'mirror' of modern society. One idea persists: it seems to be accepted that if you turn out a 'half way decent' person, that's good - ahead of any learning. So how will these children be able to work when they are older????? Social Skills are seen as a be-all and end-all, not as an in-tandem feature of education. As the 'Asperger Experts' explain on their webcasts, sensory issues must be addressed first, or the 'funnel' gets clogged up and no other learning can get through.? Yet when you look at any programmes for autistic children, Social Skills figure over and above everything else, and are considered to be the key to success.

I appreciate this explanation of evidence based practice. This is exactly in alignment with what I am being taught as a Teacher in pursuit of my Master's Degree in Education: Autism. I am currently researching evidence based practice, working on Teacher Action Research, participatory research where Autistic children have opportunities for full inclusion, leadership and enhancing skills through Peer Mediated, Modeling, Social Communication skill enhancement in high school age kids. I am also focusing on establishing each individual's Zone of Proximal Development, (Vygotsky, 1978) and utilizing Self-Advocacy and personal interests as a way to help students build interpersonal relationships, social communication, peer collaborations and self determination. I have planned for these students to work together with non-disabled peers to help navigate social understanding and acceptance in high school. I will have them collaborate to work on a Service Project to have autistic kids help "teach others" about disabilities acceptance and inclusion to help eradicate stigma and stereotypes and promote social equality among all ability level peers. This is exactly what the 100's of scholarly Journals have lead me to develop, looking at it from educational and psychological perspectives as well as "listening to the Self-Advocates from ASAN, NOS, Thinking person's guide to Autism, Autistic Adults to help build better learning environments for the future of all autistic children to have the tools necessary to transition to adulthood after the protections and services provided by IDEA run out upon graduation. Kudos to you Dr. Wilkinson. I am against all forms of aversive practice and manipulating behavior to appear someone else's definition of what normal should look like. Rewards and tokenism only goes to a point and it usually backfires as social development and expectations change over lifespan. (Floortime is a great tool with preschool aged children, I do agree with that) but beyond then a child's growth for social-emotional learning is best learning by the above methods. Music and Art are also wonderful therapies in addition to methods above.?

All of these are tools for teaching a child to behave as "normally" as possible, usually in a school setting. While they're obviously helpful for that purpose, there are two issues with what you've written. First, none of these interventions address engagement or emotional growth -- which is the purpose of interventions like Floortime, which are not mentioned here. As a result, the learner is unlikely to have an intrinsic motivation to do any of the things they're taught: all the motivation comes from the instructor, who may offer treats as a reward for compliance. The vast majority of these interventions are forms of training -- not engaging or teaching in the best sense of the word. Second, the reason that behavioral interventions are "evidence based" is that they are built around metrics and specific extrinsic "behaviors" that can be observed and checked off on a list. Therapies that engage children in symbolic play, imaginative conversation, artistic endeavors, etc., are MUCH harder to measure in that way -- and, as a result, they wind up being considered "unproven." How do you PROVE the value of learning to play the clarinet or how to admire art in a museum? What is the "purpose" of actively and intentionally engaging in make believe? These are critical humanizing skills that are left behind by behavioral interventions.
