Abstract

Introduction: Social media play an important role in society and its use has been rising both in number of users and time spent in their use. In this context, the Social Media Disorder Scale (SMD Scale) was developed and proved to be a valid and reliable measure of social media addiction. This study aimed to develop and test the fit of the Portuguese version of the Social Media Disorder Scale (SMD Scale-PT), and explore its psychometric properties in college students. Methods: A sample of 297 students, 205 women (69%) and 92 men (31%) completed online a set of self-report instruments: the SMD Scale-PT, the Depression, Anxiety and Stress Scales (DASS-21), the Internet Addiction Test (IAT) and the Nomophobia Questionnaire (NMP-Q-PT). Results: The SMD Scale-PT revealed a unidimensional factor structure, showing the following adjustment indicators: χ2/gl = 3.80, CFI = .816, GFI = .930, TLI = .754, RMSEA = .097, MECVI = .473. The Cronbach’s alpha was .67 and composite reliability was .70. The SMD Scale-PT was positively correlated with IAT and NMP-Q, which assess similar constructs. Regarding the association of SMD Scale-PT with the anxiety, depressive and stress symptoms assessed by the DASS-21, there were also positive and statistically significant correlations. Conclusion: The Portuguese version of the SMD Scale-PT, although revealing some fragilities, showed similarities in factor structure and psychometric properties with the original and Turkish versions. This study also pointed out possible modifications that may contribute to this measure improvement.
