This manuscript is a programmatic Registered Report that is expected to be the basis of two final manuscripts, one of which explores the feedback mechanisms applied researchers adopt in their work and the role of open scholarship in applied research, and the second that focuses upon climate change.

BACKGROUND: Swallowing difficulties (ie, dysphagia) are common among older adults, with a 13% to 54% prevalence. Adequate interventions to improve the swallowing function of older adults would reduce morbidity and enhance health-related quality of life outcomes. Mobile health (mHealth) apps may help alleviate dysphagia symptoms by providing programs that maximize the intensity and frequency of training without requiring high costs or regular clinic visits. OBJECTIVE: The aim of this pilot study was to assess the usability of swallowing training apps by quantitatively and qualitatively evaluating older adults' self-reported data, taking into consideration their educational levels and exposure to mobile technology. We conducted surveys and brief interviews while the participants used a swallowing intervention app we developed. We subsequently identified and resolved individual-specific usability issues to improve future implementation of the app protocol for older persons with swallowing difficulties. METHODS: A total of 11 participants (10 women, 91%; mean age 75.7 years, SD 3.93) from two district-run senior welfare centers took part in this study. The participants were divided into a high-potential group and a low-potential group based on their total number of years of education and smart device usage. To investigate the usability of the app twice (ie, in the second week of the intervention and the postintervention stage), we used mixed methods consisting of both quantitative approaches, namely the System Usability Scale (SUS) and modified Computer Self-Efficacy Scale (mCSES) surveys, and qualitative approaches (ie, interviews). RESULTS: The quantitative results of the SUS and mCSES surveys revealed that the high-potential group was more inclined to adopt and learn new technology than the low-potential group. Specifically, within the high-potential group, a Wilcoxon signed-rank test indicated that the postintervention mCSES scores (median 65.50) were significantly higher than those in the second week of intervention (median 54.00; z=-2.023, P=.04). Additionally, the usability scores in the low-potential group were within the "marginal acceptability" range even after completion of an 8-week intervention program. Qualitative analyses via semi-structured interviews yielded promising outcomes regarding app acceptability, training program utilization, emotional responses, and learning experience. CONCLUSIONS: To the best of the authors' knowledge, this usability and feasibility study is the first report of a swallowing training app designed to improve the swallowing function of older adults. Future research should consider several issues, such as user characteristics, pretraining education, and the intensity and innate characteristics of the intervention program.

BACKGROUND: Specific learning disorder (SLD) of reading skills impacts approximately 7% of children. Speech and reading therapy is currently the gold-standard intervention for improving children's reading abilities. However, intensive interventions are difficult to implement. Recently, numerous studies have investigated the interest of game- and home-based training approaches to enhance children's motivation and facilitate intensive learning activities in home settings. The serious game Poppins Clinical integrates rhythm and specific written language exercises to improve reading skills in children with SLD. OBJECTIVE: This study aimed to assess the noninferiority of Poppins Clinical combined with a reading specialist session once every 2 weeks versus a reading specialist session every week, on the reading skills of children with SLD. METHODS: A total of 306 children with dyslexia will be recruited for this study and randomly assigned to either the experimental or control group. Children in the experimental group will use the serious game Poppins Clinical at home for 20 minutes, 5 days a week, and attend 1 reading therapy session every 2 weeks. The control group will participate in one reading therapy session per week. Poppins Clinical combines rhythm and language exercises integrated into an engaging game designed to maintain user motivation. We will use a noninferiority paradigm to assess the clinical impact of both interventions in terms of reading accuracy, reading speed, and reading comprehension. We will also investigate the evolution of phonological and visual-attentional skills. However, we will explore the impact of the protocol on parental stress and children's perception of their difficulties. Finally, we will also assess the cost of medical care and the impact of introducing the serious game Poppins Clinical on reading therapy. To facilitate recruitment and ensure the representativeness of our sample, the evaluation of the children will be conducted via videoconference using standardized tests that have been adapted for videoconference administration. RESULTS: Patient recruitment is expected to start in December 2024, with study completion by the end of August 2025. CONCLUSIONS: This study should allow us to assess the interest in using the serious game Poppins Clinical in addition to reading therapy to improve reading abilities in children with SLD.
