Reading and language intervention for children at risk of dyslexia: a randomised controlled trial.

ABSTRACT:

Background

Intervention studies for children at risk of dyslexia have typically been delivered preschool, and show short-term effects on letter knowledge and phoneme awareness, with little transfer to literacy.

Methods

This randomised controlled trial evaluated the effectiveness of a reading and language intervention for 6-year-old children identified by research criteria as being at risk of dyslexia (n = 56), and their school-identified peers (n = 89). An Experimental group received two 9-week blocks of daily intervention delivered by trained teaching assistants; the Control group received 9 weeks of typical classroom instruction, followed by 9 weeks of intervention.

Results

Following mixed effects regression models and path analyses, small-to-moderate effects were shown on letter knowledge, phoneme awareness and taught vocabulary. However, these were fragile and short lived, and there was no reliable effect on the primary outcome of word-level reading.

Conclusions

This new intervention was theoretically motivated and based on previous successful interventions, yet failed to show reliable effects on language and literacy measures following a rigorous evaluation. We suggest that the intervention may have been too short to yield improvements in oral language; and that literacy instruction in and beyond the classroom may have weakened training effects. We argue that reporting of null results makes an important contribution in terms of raising standards both of trial reporting and educational practice.

Project description:Down syndrome is the most common genetic cause of intellectual disability, affecting 700-800 babies annually in the UK (Wu J, Morris J, Eur J Hum Genet 21:1016-9, 2013). Children with Down syndrome have difficulties developing language skills. These difficulties can have long-term negative consequences for all aspects of their lives including social development, education and employment opportunities, and emotional wellbeing and mental health (Irwin LG et. al 2007). These aspects all have the potential to be improved through targeted early language intervention. Parents and Children Together (PACT) is a parent-delivered early language teaching programme for typically developing pre-school children at risk of language delays. A previous project (Burgoyne K, J Child Psychol Psychiatry 59(5):545-55, 2018) showed that PACT leads to improvements in children's language and early literacy skills. Our team has worked closely with six families to adapt PACT for children with Down syndrome. The aim of the current study is to conduct a feasibility randomised controlled trial (RCT) to evaluate the feasibility of a definitive RCT and explore initial evidence of the adapted programme's potential to support children's language and literacy development. This is a two-arm feasibility randomised controlled trial in which children will be randomly allocated to either a PACT-DS group or to a waiting control group (who will receive intervention at the end of the project). We aim to recruit 28-30 children with Down syndrome (aged 3-6 years) and their parents/caregivers to take part. The PACT-DS group will be trained to deliver PACT-DS every day (20 min a day; 5 days a week) to their child over 30 weeks. We will collect data using assessments of child language and early literacy, measures of parent wellbeing, qualitative surveys and interviews, and monitoring data to explore trial feasibility (including recruitment and retention of families and adherence and acceptability of intervention) and cost and benefits. Data will be collected before intervention, immediately after the 30-week intervention programme, and 6 months after intervention ends. Clear progression criteria will be used to assess suitability for a definitive trial. This study represents initial steps in developing a definitive trial of the PACT-DS programme and will add to the limited evidence base on early language intervention for children with Down syndrome. This programme of research has the potential to make significant advancements in early language intervention research and practice for this group. The trial is registered with the ISRCTN registry: study ID ISRCTN63251282 . Registered on 14 July 2023.

Project description:Literacy is fundamental for educational achievement, and in the longer term contributes substantially to a range of life skills. Literacy difficulties during the early years of school are associated with long-term impacts on academic success, with differences in academic achievement sustained through children's schooling. Therefore, addressing literacy difficulties during the early years of school is essential in reducing the risk of children progressing onto negative academic, psychosocial and vocational trajectories. This trial will determine whether a phonics-based reading intervention can improve the reading comprehension of students identified as low-progress readers in the second year of primary school.We recruited 236 students fromnine schools after screening for reading difficulties in the second year of primary school (Year 1). Schools in Sydney and Central Coast of New South Wales will be invited to participate via an opt-out consent process. All children identified as being in the bottom 25th percentile using the Wheldall Assessment of Reading Lists will be eligible for the trial. These children will be randomised into either 'usual teaching' or 'intervention' groups. Trained school support teachers will deliver the MiniLit intervention. Intervention: In groups of four, children will complete a daily 1-hour lesson with their MiniLit teacher over 20 school weeks. Follow-up: Immediately after intervention completion and 6 months later using child face-to-face assessments. Primary outcome: Reading comprehension at 6 months after intervention completion. The study will have an embedded process and cost-effectiveness evaluation.The Building Better Readers trial will be the first efficacy randomised controlled trial comparing usual teaching with a phonics-based reading intervention for children with reading difficulties in Year 1 of primary school in Australia. The randomised design will limit the effect of bias on outcomes seen in other studies.ACTRN12617000179336.
