Functional Skills Training for Supermarket Shopping Using NFC Technology in People With Intellectual Disabilities

The general objective of the "Compra con-Migo" project is to evaluate the impact of a technological tool based on NFC (Near Field Communication) technology on the development of cognitive and instrumental skills necessary to carry out the activity of shopping in supermarkets in people with intellectual disabilities. Specifically, it is intended to analyze the evolution of performance in tasks such as planning, product recognition, calculation, payment and functional autonomy, after the use of an adapted gamified application. The research is structured as a pilot, analytical, longitudinal and prospective study, without a control group, with evaluations in three moments: pre-intervention, intermediate and post-intervention. This methodological decision responds both to ethical criteria, by avoiding denying a potentially beneficial intervention, and to logistical limitations typical of institutional environments. Statistical analysis will be performed with R, using analysis tools for repeated measurements, both parametric and non-parametric, as appropriate. The study population is composed of adults with intellectual disabilities, aged between 18 and 65 years, who regularly take part in therapy sessions in specialized centers. A sample of between 34 and 40 participants is expected. The intervention will be carried out in various Care Centers for People with Disabilities (CAPD) and associations in Galicia (Spain), specifically in the CAPD of A Coruña, Chapela, Sarria, Souto de Leixa and the O Saiar Occupational Center. This study will not only evaluate the use of the tool in real environments, but also generate evidence applicable to its future implementation in other contexts. The proposal is aligned with the principles of accessibility, technological innovation and social inclusion, and seeks to offer a structured, motivating and effective therapeutic resource.
