Abstract: The increasing presence of digital media has amplified the need to study media multitasking (both multiple media activities simultaneously and using media while doing non-media activities). Media Multitasking Scale (MMS) has been used to assess this phenomenon, but it is yet to be validated for a Portuguese population. This study analysed the validity of a Portuguese Version of the MMS ( n = 171 Portuguese adolescents) based on inter-item correlations and confirmatory factor analysis. The results suggest changes in the original version to reflect more recent digital media tendencies for a better fit to the Portuguese adolescents’ sample. Additionally, results showed that Multitasking with Media and Non-Media and Concentration Without Multitasking were partially predictors of mental health problems (predictive validity), highlighting the scale’s utility in assessing media multitasking behaviours and their impact on psychological well-being.
