This study aims to validate a scale to measure addiction to social media (SMAS) for the Portuguese population (SMAS-PV). The original 14 items’ SMAS was translated and back-translated from English to Portuguese. Psychometric scale validation procedures were followed. SMAS-PV’s properties were assessed in a sample of 605 Portuguese university and high-school students. A Parallel Analysis was carried out as a criterion for extracting factors in Exploratory Factorial Analysis (EFA), EFA for ordinal data, with unweighted least squares (ULS). This was followed by confirmatory factor analysis to examine whether the structure pattern fitted the Portuguese context. The resulting scale, with eight items in a two-component structure, compulsive feelings, and social consequences, demonstrated high reliability and validity. The Portuguese version of the social media addiction scale presented good psychometric qualities, constituting a credible instrument for assessing social media addiction. Participants with the highest addiction levels spend more time connected to social media.

Keywords : Social media addiction scale; Problematic use of social media; Validation; Psychometric properties.
