Resumo

O propósito deste estudo foi testar a eficácia e o efeito sustentado (follow-up) de uma intervenção de mindfulness de quatro semanas na redução da ansiedade e estresse em um grupo de estudantes universitários brasileiros. A intervenção foi adaptada para ser disponibilizada pelo aplicativo Neurosaúde, criado como parte deste trabalho para servir de plataforma para a intervenção. A pesquisa como um todo ocorreu em ambiente virtual, sendo recrutados 48 participantes que foram alocados randomicamente para o grupo intervenção ou para o controle de lista de espera. Medidas foram utilizadas para acessar os níveis de mindfulness, ansiedade e estresse antes, após a intervenção e no follow-up de quatro semanas. Aplicando a análise por intenção de tratar, encontramos diferenças significativas entre os grupos para a medida de ansiedade no follow-up com um tamanho de efeito grande (F (2.92) = 10.275, p = 0.000, η2 = 0.183). Nossos resultados sugerem que a intervenção de mindfulness de quatro semanas por meio de um aplicativo móvel foi capaz de agir como um fator protetor contra a ansiedade desenvolvida pelos estudantes universitários durante a
ocorrência da pandemia causada pelo Covid-19, visto que, enquanto o grupo tratamento manteve níveis reduzidos de ansiedade, o grupo controle demonstrou um contínuo aumento de ansiedade no pós-teste e follow-up que coincidiu com a primeira onda de Covid-19 na região onde os participantes residiam.
