Resumo(s)
As funções executivas (FE) têm um papel central no desenvolvimento cognitivo, social e académico, sendo a sua avaliação precoce essencial para prevenir dificuldades futuras. A realidade virtual (RV) surge como ferramenta inovadora, ao oferecer ambientes imersivos, ecológicos e motivadores para a avaliação cognitiva. Este estudo teve como objetivo analisar a fiabilidade, validade e aplicabilidade clínica do Cogniclear VR na avaliação das FE em crianças dos 8 aos 14 anos. A amostra integrou 47 participantes, dos quais 12 foram avaliados com a Bateria de Avaliação Neuropsicológica de Coimbra (BANC). Os resultados indicaram consistência interna adequada (α = .824) e correlações positivas e significativas entre domínios específicos do Cogniclear VR (memória, atenção e linguagem) e provas equivalentes da BANC, sugerindo validade preditiva parcial. Verificaram-se diferenças consistentes entre crianças com e sem perturbações do desenvolvimento, reforçando a validade discriminante do instrumento. Conclui-se que o Cogniclear VR revela potencial como ferramenta para a avaliação das FE em contexto pediátrico, ao superar limitações das metodologias tradicionais, como tempo prolongado de aplicação, baixa motivação e menor validade ecológica. Apesar das limitações inerentes ao desenho piloto e ao tamanho da amostra, estes resultados reforçam a pertinência de integrar a RV na prática clínica da Terapia Ocupacional (TO).

The sample included 47 participants, of whom 12 were also assessed with the Coimbra Neuropsychological Assessment Battery. Results indicated adequate internal consistency (α = .824) and significant positive correlations between specific Cogniclear VR domains (memory, attention, and language) and equivalent BANC tasks, suggesting partial predictive validity. Consistent differences were also observed between children with and without developmental disorders, reinforcing the discriminant validity of the instrument. In conclusion, Cogniclear VR shows potential as a tool for EF assessment in pediatric contexts, overcoming limitations of traditional methodologies, such as lengthy administration time, low motivation, and reduced ecological validity. Despite the limitations of a pilot design and small sample size, these findings reinforce the relevance of integrating VR into Occupational Therapy clinical practice
