Resumo
A Escala de Tecnostresse RED/TIC é um instrumento de autorrelato para avaliar e
diagnosticar o stresse induzido pelas novas tecnologias de informação e comunicação, o
designado Tecnostresse. O presente estudo teve como objetivo analisar a validade de
construto, a fiabilidade interna e a sensibilidade da versão traduzida e adaptada da escala para
o contexto português europeu.
O presente estudo é de natureza psicométrica, transversal, com uma amostra de 327
participantes (M idade = 32,72; DP = 12,28) de ambos os sexos e falantes nativos do Português
europeu. Os resultados da análise fatorial confirmatória revelaram um melhor ajustamento aos
dados pelo modelo multifatorial de quatro fatores correlacionados. Relativamente à
consistência interna, os valores do alfa de Cronbach, da fiabilidade compósita e da
homogeneidade apresentaram uma fiabilidade adequada para todas as dimensões da escala.
As validades convergente e divergente foram calculadas através da Variância Extraída Média,
da Variância Média Compartilhada, da Variância Máxima Compartilhada e dos coeficientes
de Correlação de Pearson, contudo apenas se verificou validade convergente entre a escala em
estudo e a de comparação, não tendo sido possível confirmar a existência de validade
divergente. Os itens da escala apresentaram ainda uma sensibilidade adequada.
Segundo o nosso conhecimento, a primeira tradução da RED/TIC ocorreu ainda antes
da inclusão da quinta dimensão e não foi realizada uma AFC para confirmar os resultados.
Este estudo é, portanto, o primeiro a validar a RED/TIC atualizada para o contexto português
europeu. Os seus resultados sugerem tratar-se de um instrumento de avaliação válido que
poderá ser aplicada em contexto de investigação e/ou na prática clínica.
The RED/TIC Technostress Scale is a self-report instrument to assess and diagnose stress induced by the new information and communication technologies, called technostress. The present study aimed to analyze the construct validity, internal reliability and sensitivity of the translated and adapted version of the scale for the European Portuguese context. The present study was of psychometric nature, transversal, with a sample of 327 participants (Mage = 32.72; SD = 12.28) of both sexes and native speakers of European Portuguese. Results from the confirmatory factor analysis revealed that the correlated fourfactor model had a better adjustment to data. Regarding internal consistency, Cronbach's alpha, composite reliability and homogeneity values showed adequate reliability for all dimensions of the scale. The convergent and divergent validities were calculated using the Average Variance Extracted, the Average Shared Variance, the Maximum Shared Variance and Pearson's Correlation coefficients, however, there was only convergent validity between the scale under study and the comparison, and it was not possible to confirm the existence of divergent validity. The scale items also showed adequate sensitivity. To our knowledge, the first RED/TIC translation occurred before the inclusion of the fifth dimension and a CFA was not performed to confirm the results. This study is therefore the first to validate the updated RED/TIC for the European Portuguese context. Its results suggest that it is a valid assessment instrument that can be applied in research and / or in clinical practice.
