LEAP and Autism Ranking: Limited positive evidence

Children in class

LEAP (an acronym for Learning Experiences - An Alternative Program for Preschoolers and Parents) is a comprehensive, multi-component, educational programme in which small groups of autistic children are taught alongside a small number of typically developing children.

LEAP is based on the idea that autistic children will learn better in integrated settings alongside their typically developing peers provided that those peers have been taught how to help them.

LEAP aims to help children to reach their full potential so they are best able to benefit from mainstream education. The LEAP curriculum is designed to concentrate on the development of functional skills, independent play, social interaction, pre-academics, language skills and adaptive behaviour.

Each autistic child has an individually designed educational plan, which includes the mainstream curriculum, as well as specific, personalised objectives.

Our Opinion

There is a very small amount of high quality research evidence (two large, multi-site controlled trials) and a small amount of low quality research (six single-case design studies with three or more participants) into the use of LEAP for pre-school autistic children. 

This research suggests that LEAP may be an effective way to improve the social communication skills of some pre-school autistic children.

There is insufficient evidence to determine if LEAP provides any benefits in other areas (such as a reduction in repetitive and restricted behaviours, interests and activities) to pre-school autistic children.

There could be dangers if LEAP is applied without following the relatively strict guidance, specifically if it is confused with putting children into mainstream schools with little or no support.

There is a need for more research into LEAP which uses scientifically robust, experimental methodologies. That research should investigate whether LEAP is more or less effective than other comprehensive, multi-component, educational interventions (such as TEACCH), and which components of LEAP, if any, are more likely to benefit specific autistic individuals.

Audience

LEAP was designed for pre-school children aged three to five, some of whom are autistic and some of who are not. For example, according to the Watson Institute (2010),

“Typically developing children age 3-5 who have no need for early intervention services are an integral component of LEAP Preschool. The curriculum is developmentally appropriate, helping to prepare them for kindergarten and beyond.” This is because LEAP “focuses on enhancing the skills of children with autism through interaction and play with typically-developing peers.”

Aims and Claims

Aims

LEAP is designed to achieve a number of aims. For example, according to the Watson Institute (2010),

“The goal of LEAP Preschool is for all children to reach their full potential so they are best able to benefit from the curriculum in their home school district.”

and

“To best meet the needs of children with autism, the preschool curriculum is supplemented with learning activities and instructional strategies specifically designed to concentrate on the development of functional skills, independent play, social interaction, pre-academics, language skills and adaptive behavior.”

Claims

There have been various claims made for the use of LEAP as an intervention for pre-school autistic children. For example, Strain and Bovey (2011) claimed

“… (a) Children in LEAP generally show significant reductions in autistic symptoms after 2 years of intervention, comparison children do not; (b) children in LEAP make marked developmental progress on intellectual and language measures, comparison children do not; (c) on observational measures taken in school and at home, LEAP children are far more socially engaged and appropriate; (d) no negative and some positive (e.g. better social skills and fewer disruptive behaviors) outcomes accrue to typical children in the LEAP model; (e) gains for LEAP children maintain following program participation with 24 of 51 children enrolled in regular education classes with no signs of developmental regression; and (f) adult family members who participated in LEAP are significantly less likely than comparison families to show signs of significant stress and depression following the early intervention experience.”

Key Features

LEAP (an acronym for Learning Experiences - An Alternative Program for Preschoolers and Parents) is a comprehensive, multi-component, educational programme in which small groups of autistic children are taught alongside a small number of typically developing children.

LEAP is based on the idea that autistic children will learn better in integrated settings alongside their typically developing peers provided that those peers have been taught how to help them.

LEAP aims to help children to reach their full potential so they are best able to benefit from mainstream education. The LEAP curriculum is designed to concentrate on the development of functional skills, independent play, social interaction, pre-academics, language skills and adaptive behaviour.

Each autistic child has an individually designed educational plan, which includes the mainstream curriculum, as well as specific, personalised objectives.

According to Strain and Bovey (2011),

“The LEAP model has a number of unique features that contribute to its effectiveness and relatively lower costs. These features include the following:

“1. Inclusion begins full-time from Day 1 in LEAP preschool classrooms. Children with ASD are provided with the necessary level(s) of prompting, classroom and curricular adaptations and modifications, and general support to participate immediately in peer-mediated social skill intervention.

“2. The design of LEAP classrooms begins with establishing a setting of high quality for typically developing children. LEAP has been implemented effectively in classrooms utilizing a variety of preschool models and curricula … In the context of this programming, systematic intervention is embedded in typical preschool routines (e.g. circle time, free play/centers, snack, small groups, etc.) with the aim of offering hundreds of meaningful, socially relevant learning opportunities every day.

“3. Typically developing children play a major intervention role in LEAP. The typically developing children are provided with comprehensive social skills training such that they can facilitate the social and communicative behaviors of peers with ASD. This systematic, peer-mediated instruction has been shown to produce a Day-1 intervention effect for the children with ASD.

“4. Learning objectives are written in such a fashion that teaching continues until generalized behavior change is achieved. Learning objectives are further described according to relevant prompting hierarchies. Thus, program data are collected on children’s behavioral movement toward the rigorous standard of independent, generalized performance, not in terms of percentage correct, trials accomplished, or similar indices. Data are reviewed daily and strict decision-making rules demand intervention changes in the absence of clear behavior change.

“5. Skill training for families focuses on providing adult family members with the behavioral teaching strategies sufficient for them to experience less stress and more pleasure in daily routines, such as meals, bedtime, dressing, and community outings.

“6. Intensity in the LEAP model is not defined by hours per week that individuals are paid to deliver service. We believe that the algorithm defining intensity is complex and includes, for each developmental domain of concern, the following factors: (a) number of meaningful opportunities to respond, (b) the functionality of objectives chosen, (c) the selection of an instructional method that maximizes children’s engagement and minimizes errors, (d) the competence of staff to deliver with fidelity the chosen intervention, and (e) the use of data systems and decision-making rules that minimize children’s exposure to less-than optimal interventions.

“7. LEAP is unique in that we utilize a variety of science-based intervention approaches, including (a) peer-mediated interventions, (b) errorless learning, (c) time delay, (d) incidental teaching, (e) pivotal response training, (f) picture exchange communication system, and (g) positive behavior support. We believe the enormous heterogeneity of ASD precludes the use of one or a few instructional approaches. “

Cost and Time

Cost

The major costs of using LEAP are the salaries and associated costs of the teaching staff at the school where LEAP is delivered.

According to Strain and Bovey (2011),

“The resource allocation implications are nothing less than profound as LEAP’s costs are estimated at US$20,000 per child per year versus between US$45,575 and US$69,050 for one-on-one, discrete-trial methods.”

There may also be costs for any training that is undertaken (which may include travel, accommodation and learning materials), and any equipment and materials used.

Time

LEAP is designed to be delivered over half a day on every school day during the school term. According to the Watson Institute (2010),

“Sessions are 2 1/2 hours long, 5 days a week in the morning or afternoon, 11 months a year.”

Risks and Safety

Hazards

There are no known hazards for LEAP.

Contraindications

There are no known contraindications (something which makes a particular treatment or procedure potentially inadvisable) for LEAP. However there could be dangers if LEAP is applied without following the relatively strict guidance, specifically if it is confused with putting children into mainstream schools with little or no support.

Suppliers and Availability

Suppliers

The Watson Institute has three LEAP preschool locations in Pennsylvania. A number of other schools in the US have now adopted the LEAP model, either by undertaking the training provided by the Watson Institute or by purchasing the relevant manuals. We have been unable to identify any providers of LEAP in other countries.

Credentials

Teachers and other professionals involved in LEAP, such as speech and language therapists, will have a range of different credentials and qualifications.

Other people, including parents and other members of the family, may also be involved. They do not need any formal qualifications, although most will have studied the materials published by the Watson Institute or attended one or more of their courses.

However, Strain and Bovey (2011) reported that it took two years before most teachers were able to implement LEAP as it was designed to be used.

History

The LEAP approach was developed by Strain, Kohler, and colleagues at Allegheny-Singer Research Institute in Pennsylvania in the US in the 1980’s.

It has since been implemented by a number of providers, the best known of which is probably the Watson Institute in Pennsylvania.

Current Research

We have identified nine studies of LEAP published in English-language, peer-reviewed journals. These studies included more than 500 autistic children aged from three to five, although the majority of these children came from just two studies (Strain and Bovey, 2011 with 294 participants; Boyd et al, 2014 with 198 participants).

The study by Strain and Bovey (2011) compared two versions of LEAP with each other: the full-scale LEAP replication training or a comparison condition in which staff were provided with LEAP intervention manuals and related written materials only. It included 294 pre-school children and was conducted in 56 classrooms in seven different states within the US. It reported that the children who received the full version of LEAP were found to have made significantly greater improvement than the other group on measures of cognitive, language, social, and problem behaviour, and autism symptoms.

The study by Boyd et al (2014) compared LEAP with TEACCH and with non-model specific practices (standard teaching). It included 198 pre-school children and was conducted in 74 different classrooms in four different states within the US. It reported that each of the three interventions produced significant benefits such as improvements in autism characteristics and severity, communication skills and reciprocal social interactions. None of the three interventions produced any changes in sensory and repetitive behaviours.The other studies all looked at various early versions of LEAP and all of them reported gains in areas such as social communication skills.

Status Research

There are a number of limitations to all of the research studies published to date. For example

  • The majority of studies (seven) used single-case designs (such as multiple baseline or withdrawal) and included six or less participants.
  • Some of these studies were vague about some of the details of the study. For example, the study by Hoyson, Jamieson, Strain (1984) described the participants as “autistic-like”, making it unclear if they had actually received a formal diagnosis of autism.
  • The study by Strain and Bovey (2011) had a number of limitations including the fact that the researchers made no direct observational measures of child behavior; the participants all appeared to be in the moderate to severe range of autism; and the children in the full replication classes were only exposed to a brief period of time during which most components of the intervention were in place.
  • The study by Boyd et al (2014) had a number of limitations including that the researchers used raw versus standard scores for some measures; the researchers were reliant on school officials to nominate classrooms/teachers to participate in the study; there were some pre-treatment differences between groups; the assessors were not blind to the children’s group assignment; and the control condition used may represent the ‘‘best’’ of standard practice and may differ substantially from the modal level of quality that reflects ‘‘business-as-usual’’ classroom practices.
  • Most of the studies were undertaken by researchers who were not independent of the interventions being studied. Those researchers may therefore have been biased towards the intervention, however unconsciously.
  • None of the studies appeared to involve autistic people or their parents and carers in the design, development and evaluation of those studies.

Future Research

Summary of Existing Research

There is a very small amount of high quality research evidence (two large, multi-site controlled trials) and a small amount of low quality research (six single-case design studies with three or more participants) into the use of LEAP for pre-school autistic children.

This research suggests that LEAP may be an effective way to improve the social communication skills of some pre-school autistic children.

There is insufficient evidence to determine if LEAP provides any benefits in other areas (such as a reduction in repetitive and restricted behaviours, interests and activities) to pre-school autistic children.

Recommendations for Future Research

There is a need for more research into LEAP which uses scientifically robust, experimental methodologies.

That research should investigate whether LEAP is more or less effective than other comprehensive, multi-component, educational interventions (such as TEACCH), and which components of LEAP, if any, are more likely to benefit specific autistic individuals.

That research should be undertaken by researchers who are independent of the interventions being studied. That research should also involve autistic people and their parents and carers in the design, development and evaluation of those studies.

Additional Information

According to Boyd et al (2014), in their comparison of LEAP, TEACCH and standard teaching practices

“All three programs were found to produce statistically significant changes in children’s outcomes across the school year. This finding may shift the field’s thinking around [comprehensive treatment models] designed for students with ASD. Perhaps it is not the unique features of the models that most contribute to child gains; instead it is the common features of the models that most influence child growth… Early analysis of the overlap of scores on the fidelity measures indicate that perhaps those components common to the intervention approaches (e.g. classroom organization, teacher interaction with students and families) account for outcomes more than components that are unique to each approach (e.g. peermediated instruction in LEAP classrooms, structured work systems in TEACCH classrooms)”.
