Facebook Addiction Scale: exploratory validity studies

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

This paper intends to develop the first validity studies of a Portuguese version of Facebook Addiction Scale (AFS) by Koc and Gulyagci (2013). The study was carried out with a convenience sample (N=144), through a questionnaire made available online. Statistical analyzes of the results suggest that the scale has excellent psychometric properties, similar to those of the original scale. Analysis of the principal components, with varimax rotation, reveals the existence of a single factor, able of explaining 63,7% of the total variance, while the internal consistency analysis is .91 (Cronbach’s alpha).
