Abstract(s)
Introdução: A utilização da internet generalizou-se na última década. Este meio traz inúmeras vantagens, mas têm sido reconhecidos padrões de uso que podem ter consequências na saúde mental dos utilizadores. O objectivo do presente trabalho é sintetizar a evidência disponível acerca desta relação.
Métodos: Realizou-se uma pesquisa nas bases de dados PubMed e BioMedCentral por artigos originais que investigassem esta relação, com enfoque em estudos longitudinais, excluindo protocolos e estudos transversais.
Resultados: Foram seleccionados 14 artigos. A maioria dos estudos incidiu sobre a faixa etária dos adolescentes e adultos jovens. Verificaram-se associações significativas entre determinados padrões de uso da internet e a diminuição da saúde mental ou bem-estar. Algumas destas relações eram mediadas por factores como a diminuição de horas de sono ou a exposição a cyberbullying. Quase todos os estudos avaliaram variáveis por meio de escalas auto-reportadas, constituindo uma limitação significativa da evidência obtida.
Conclusão: O uso excessivo ou problemático da internet tem correlações positivas com sintomatologia e patologia psiquiátrica. Não é possível estabelecer com a evidência actualmente disponível uma relação de causalidade entre o uso da internet e possíveis efeitos deletérios sobre a saúde mental. Existe necessidade de realização de estudos que permitam obter evidência mais robusta acerca desta relação, assim como uma uniformização da terminologia e conceito de utilização problemática da internet.
Introduction: Internet use has grown massively in the past decade. This medium carries countless possibilities, but certain patterns of use have become apparent that may have deleterious consequences on users’ mental health. The present study aims to review and synthesize the evidence currently available on this link. Methods: An online database search was conducted, via PubMed and BioMedCentral, for original studies that investigated the relationship between internet/social media use and mental health, focusing on longitudinal studies and excluding study protocols as well as cross-sectional studies. Results: 14 studies were included. The majority centered on younger populations, i.e. teenagers and young adults. Positive associations were found between certain patterns of use and poorer mental health or wellbeing. Some of these were found to be mediated by factors such as inadequate sleep or exposure to cyberbullying. Nearly all studies found included self-report measures, which constitutes an important limitation in the obtained evidence. Conclusion: Excessive or problematic internet use has positive correlations with psychiatric symptoms and pathology. It is not possible to establish a causal link between internet use and any possible negative effects on mental health, based on the current available evidence. There is a need for studies with designs capable of investigating this correlation, as well as a more precise definition of the terminology and concept of problematic internet use.
