Stability in Reading Improvement After Home-Based Multi-Componential Training for Children with Developmental Dyslexia

Background: RIDInet-Reading Trainer 2 (RT-2) is a web-platform for the remote treatment of developmental dyslexia (DD) which has been shown to improve reading performance. However, no previous studies have investigated stability in reading improvement after RT-2 training and the influence of a previous diagnosis of developmental language disorder (DLD) and of participants' age on stability. Objectives: In a sample of 52 Italian-speaking children with DD who participated in a 3-month home-based treatment with RT-2, we aimed (1) to assess the stability in reading improvement after RT-2 training at a 3-month follow-up and the potential moderating role of DLD and age; and (2) to evaluate the impact of RT-2 training in reading comprehension. Results: By implementing linear mixed model analysis, our findings confirmed reading improvement after RT-2 training in word and text reading in DD. Moreover, we observed an overall stability in single-word and text reading speed performances after three months, regardless of the diagnosis of DLD and the age of the participants. Conversely, accuracy showed an overall stability for single-word reading, while it was significantly stable only in the younger participants in text reading. The improvement was educationally relevant as it impacted reading comprehension. Conclusions: The current study supports the use of remotely delivered DD interventions among school-aged children.
