BackgroundThere is a paucity of research into interventions that help people with intellectual disabilities learn to read. This feasibility study examines whether an online reading programme, Headsprout, with additional support strategies and supervision (the intervention), can be delivered by support workers/family carers and the feasibility of conducting a later large-scale effectiveness trial.MethodsThe study used a 2-arm randomised controlled trial (RCT) design with an embedded process evaluation using a mixed methods approach.ResultsThirty-six adults with intellectual disabilities were recruited. Informed consent and data were obtained remotely. Progression criteria for recruitment, retention, randomisation and usual practice were met; intervention adherence and fidelity were poor. Pressure on support services was a key barrier.ConclusionsWhilst progression to a large-scale effectiveness trial was not recommended, the success of conducting an RCT and remotely obtaining informed consent and data from adults with intellectual disabilities opens opportunities for increased participation in research for a currently under-represented group.

Children with intellectual disabilities often find acquiring age-appropriate reading skills difficult. We evaluated the impact of a structured online reading intervention on the reading skills of children aged 5-11 years in special educational needs (SEN) schools in England. A two-armed cluster randomised controlled trial (cRCT) compared Headsprout Early Reading (R) (HER (R)) with education as usual (EAU). Children completed the Dynamic Indicators of Basic Early Literacy Skills (R) measure online before randomisation and 1 year later. Fifty-five SEN schools (382 children) were randomised to HER (R) or EAU. Children in HER (R) schools made no additional progress in reading, on average, compared to children in EAU schools (Hedges' g = -0.01, 95% CI [-0.28, 0.26]). HER (R) seemed to have a positive impact on oral reading fluency (IRR = 0.77, 95% CI [0.60, 0.98] SE = 0.1), but these data were only available for 55% of children. Intervention compliance was low, with only ten children completing >= 40% of HER (R). HER (R) was not implemented as planned and attrition was relatively high in the intervention group, compared with EAU. It is therefore difficult to draw firm conclusions. We successfully recruited SEN schools and children, suggesting large-scale RCTs in SEN schools may be feasible; however, challenges must first be overcome to ensure acceptable implementation.

Implementation support is a key factor in the success of school-based well-being programmes. To assess the impact on children's well-being of providing additional implementation support for staff delivering a universal Acceptance and Commitment Therapy informed well-being curriculum ('Connect PSHE') compared to delivery without support. Twenty schools were recruited and randomised to deliver Connect PSHE with additional support (n =10; n = 323 children) or Connect PSHE with the standard support (n = 10; n = 422 children). A twoarm, parallel-group cluster-randomised (schools as clusters) controlled trial design was utilised. Additional implementation support had no impact on the primary well-being measure (Me and My Feelings scale) at posttest (beta = 0.22, 95 % CI [-0.59, 1.03], p = 0.59). Small improvements were observed in the additional support arm for two subscales of the Strengths and Difficulties Questionnaire. Overall, both trial arms were associated with improvements in children's well-being. Connect PSHE is a promising well-being programme suitable for testing in additional research.

Purpose There is a sparsity of research that considers how to overcome implementation challenges for interventions in special school settings where specialist teaching methods are involved. Successful implementation has often relied on considerable researcher involvement, making them inaccessible and not sustainable for the majority of special schools. The purpose of this study was to implementa train-the-trainer approach to train teaching staff to use the Teaching Early Numeracy to Children with Developmental Disabilities (TEN-DD) programme in a large special school in the UK, thereby significantly reducing researcher involvement in its implementation. Design/methodology/approach One staff member was trained to become the school lead for TEN-DD and trained other teaching staff in the school on implementation. This study recruited 13 students aged between 12 and 16 years of age with developmental disabilities to receive TEN-DD. Pre- and post-intervention tests on a standardised numeracy measure were conducted. Findings A train-the-trainer model was developed and successfully delivered to train teaching staff in TEN-DD. A standardised outcome measure indicated that ten students made improvements to their numeracy skills after teachers trained using this approach delivered TEN-DD for between 3 and 10 months. Originality/value Very little research has been carried out to better understand methods for overcoming implementation challenges for delivering evidence-based teaching programmes at scale to students with developmental disabilities who attend special schools. To the best of the authors’ knowledge, this study reports the results of the first evaluation of using a train-the-trainer model for the delivery of a numeracy intervention (TEN-DD), whereby there was no involvement of researchers in implementation beyond the initial training of the school lead. This model of training for interventions may be more sustainable for special schools and help improve the uptake of evidence-based interventions.

PurposeWith a historic lack of attention to synthesis methods such as systematic review and meta-analysis and a lack of randomised controlled trials, the evidence base for behavioural interventions for children and adults who are autistic or are diagnosed with developmental disabilities is patchy. The Sharland Foundation Developmental Disabilities Applied Behavioural Research and Impact Network (SF-DDARIN), a network of like-minded researchers and practitioners across the UK, aims to address this. The purpose of this paper is to describe the network's work and provide the context for the remaining articles in the special issue that exemplify network projects.Design/methodology/approachIn this case study paper, the authors describe how the SF-DDARIN works and is resourced, detailing the process used to maximise research opportunities by facilitating network members working together. The authors outline the progressive research steps that the SF-DDARIN has identified are needed to develop and improve the evidence base for behavioural interventions systematically and, with examples, describe how the network delivers these steps.FindingsSince its establishment in 2016, the SF-DDARIN network members have collectively worked on more than 53 projects involving over 50 researchers, had over 120 special schools contribute to projects and have recruited over 500 participants. This has been achieved through funding from the Sharland Foundation, primarily to cover the staffing costs of a small support team and internship partnerships with external organisations. Some projects have attracted external funding.Originality/valueSF-DDARIN may provide an innovative, effective and resource-efficient model for other groups seeking to develop and extend their evidence base in developmental disability research.

Purpose Children with developmental disabilities (e.g. learning disability and autism) often struggle with handwriting skills. This study aims to implement an adapted handwriting programme for children with developmental disabilities to improve their handwriting skills. Design/methodology/approach Six children with developmental disabilities aged 9–15 years received an adapted Handwriting Without Tears® (HWT) programme in small groups over eight weeks. The programme was delivered by typical teaching staff (i.e. paraprofessionals) at a special education school following a brief training session and with ongoing supervision. A range of measures assessed the children’s handwriting and related skills. Social validity interviews were conducted with school staff following the intervention to evaluate the programme’s acceptability. Findings Typical teaching staff implemented the handwriting programme with 92.3% average fidelity and delivered a minimum of three sessions per week. Social validity interviews demonstrated the acceptability of the intervention to school staff. After eight weeks of intervention, all children improved their handwriting on various assessments. Improvements were only partially maintained at follow-up. Originality/value This study supports the feasibility of using an adapted HWT programme to teach handwriting to children with developmental disabilities in special education settings. Typical teaching staff can be trained to support the delivery of the programme to children in small groups.

The Picture Exchange Communication System (PECS) is an Augmentative and Alternative Communication (AAC) system which is widely used to support children with developmental disabilities. In the present study, we surveyed individuals responsible for implementing PECS in special educational settings in the United Kingdom (N=283). We explored knowledge of and adherence to the intervention, with a view to identifying training and support needs. Specifically, we examined participants’ knowledge, implementation accuracy, training experiences, access to resources, and attitudes towards PECS. We developed hierarchical logistic regression models to explore the association between training experience and both knowledge and use of PECS. We pre-registered our methods, predictions and the analysis plan on the Open Science Framework (OSF).We found considerable variation in practitioner knowledge and implementation of PECS. Formal training predicted greater knowledge and more accurate implementation when practitioner role and the degree of setting support were accounted for. While PECS was rated by a large majority to be effective and practical, many participants identified that time and the availability of resources were barriers to implementation. We also found that the purpose of PECS was not always fully understood by practitioners, and we identified some consistent gaps in knowledge and implementation. This study contributes new information regarding the real-world use of PECS in educational settings and offers new insights for supporting practitioners.

Longitudinal research is crucial to fully assess the putative impact of the COVID-19 pandemic on children with an intellectual disability in special school settings-ideally drawing on data pre-pandemic to be able to evaluate later impact. Data on challenging behaviour and adaptive skills were collected annually for 348 students in one special school across four time points pre-pandemic and one time point post-pandemic. Data were analysed using multilevel models with repeated observations over the five time points. There was a decrease in aggressive and destructive behaviours and a decrease in adaptive skills at the post-pandemic time point, after accounting for other important covariates. There was no evidence of a change in stereotyped or self-injurious challenging behaviours. Other research using longitudinal methods is rare, but the current findings are consistent with previous research reporting on the impact of COVID-19 on children and young people, particularly from parent reports. Future considerations for schools include adopting appropriate strategies to support learners to reintegrate back into education. Further research is needed to look at the longer-term impact of the pandemic on challenging behaviour in children with an intellectual disability.

Since 2020, changes to the school curriculum in England and Wales have made elements of Personal, Social, and Health Education (PSHE) statutory. As schools grapple with these changes, alongside the psychosocial impact of the Coronavirus pandemic, it is important to consider effective ways of helping children make safe decisions and improve their overall mental health/wellbeing. Previous research has demonstrated the benefits of Acceptance and Commitment Therapy (ACT) as a treatment for range of psychological and behavioral disorders. As an extension of this, the DNA-V model provides a way of teaching children and adolescents the same psychological skills targeted within the ACT model in a more developmentally informed manner. Using scripted lesson plans, the Connect PSHE curriculum offers a research-informed curriculum for 4- to 11-year-olds so teachers can introduce the DNA-V model alongside the six ways to wellbeing. In this paper, we aimed to explore teachers' (N = 6) experiences of implementing Connect PSHE within a primary school context. Through semi-structured interviews and thematic content analysis, we identified six themes around the implementation process: (1) buy-in and engagement, (2) training and support for teachers, (3) program design, (4) creating a psychologically safe environment, (5) online delivery, (6) benefits. We outline how these findings support the existing literature around school-based ACT and reflect upon some of the feedback for future development.

Background and aimsAlthough there are several published systematic reviews and meta-analyses of the effectiveness of the Picture Exchange Communication System (PECS) protocol, no previous review has focused on factors affecting its implementation. The present review attempted to identify potential barriers and facilitators in implementing PECS, as well as examining authors’ and stakeholders’ views and experiences in terms of implementation.Methods and proceduresA total of 49 studies were identified through a systematic review search process and were included in the data extraction phase. A Content Analysis of previous researchers’ comments was also carried out.Outcome and resultsDuring the data extraction and synthesis phase, it became evident that important features of PECS interventions are not systematically reported in published literature. Thus, our primary research question remained partially unanswered. A Content Analysis of previous researchers’ comments revealed four potential implementation factors, including Contextual & Environmental Factors, PECS Training/Consultation, Supervision and Implementation Fidelity and Adherence to the Protocol.Conclusions and implicationsThe identification of potential barriers or facilitators affecting the implementation of PECS is not currently possible. The present review’s identified implementation factors were extracted from qualitative analysis of previous researchers’ anecdotal remarks or from the social validity measures. Implications in terms of previous PECS literature findings are discussed.Systematic review registration: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42018099767.

Reading is an essential life skill that can lead to independence. However, many individuals with autism and/or intellectual disabilities find this skill difficult to acquire. Computer-assisted instruction (CAI) is one approach that combines recommended reading elements (e.g., phonics, fluency, and comprehension) with evidence-based teaching strategies to support the development of reading skills. The first aim of this systematic review (PROSPERO: CRD42021253686) was to identify CAI reading programs and their effectiveness for individuals with autism and/or intellectual disability. A second aim was to evaluate the views and experiences of those with autism and/or intellectual disability, their teachers, and other stakeholders about CAI reading programs. Electronic searches of 7 databases identified a total of 3539 records for review, with 262 full-text articles evaluated, and 47 papers included in the review for data extraction and quality appraisal. The review identified both single-component and multicomponent CAI reading programs that were commercially available interventions (e.g., Headsprout©, ABRACADABRA) and bespoke interventions (e.g., personalized e-books). Thirty-four of the 47 studies reported positive outcomes in terms of effectiveness. However, the quality of these studies was often poor, and the description of the interventions was often limited (e.g., rationale for the intervention, who delivered it and how), leading to concerns about the rigor of the evidence base. Stakeholders’ views and experiences were reported in half of the evaluated studies. CAI reading programs were reported as enjoyable and easy to use. They were considered effective by the stakeholders. Further research is needed to develop and explore the effectiveness of CAI reading interventions using rigorous study designs, so that individuals with autism and/or intellectual disability can be provided with access to a wider range of evidence-based reading programs.

Many students with learning disabilities find it difficult to acquire basic reading skills. This is even more of a challenge for students who are non‐vocal. The purpose of the present study was to pilot the use of Headsprout Early Reading© (HER©), an online reading programme, with four non‐vocal students with a severe learning disability (SLD), over the course of a nine‐week period. Additional table‐top activities were designed and implemented to augment the online instruction. None of the students completed the programme. Three students improved their early reading skills over the course of the intervention. Staff members indicated positive experiences of using HER©, especially mentioning how motivated the students were to engage with the programme. HER© for students with SLD requires one‐to‐one support and a longer implementation period to achieve completion; these have implications for resourcing in special schools. However, HER© shows promise with non‐vocal students with learning disabilities and evidence supports the need for larger‐scale evaluation research.

The importance of reducing restraint and restrictive interventions in special schools has been recognised across the four nations of the UK. Government guidance for England and Wales, and recommendations produced by Restraint Reduction Scotland, both reference Positive behavioural support (PBS) as an evidence-based approach that can be used to proactively support pupils with, or at risk of, behaviours that challenge. The Department of Education of Northern Ireland recommends the development of behaviour support plans to support children with special education needs and disabilities. Special schools, however, also have a responsibility to set high expectations for every pupil, to provide access to the respective national curricula and to meet individual needs. School-wide positive behavioural support (SW-PBS), originated in the USA in the 1990s in response to a body of evidence that showed improved social and academic outcomes when behavioural interventions were implemented across whole school settings. It is increasingly being adopted in the UK. Drawing upon examples from schools in England and Wales with which the authors are familiar, this paper outlines the rationale for a special schools' model of SW-PBS and illustrates the ways in which this can be adjusted to meet the specific needs of each setting.Key Points Reducing restraint and restrictive interventions in schools is a high priority across all four nations of the UK. Special schools also have a responsibility to provide children with special education needs and disabilities positive learning environments that maximise learning opportunities and meet individual needs. School-wide positive behaviour support (SW-PBS) provides a useful framework to help special schools meet these expectations.
