The objective of this study was to provide evidence of validity and reliability of BFAS scores. A sample of 510 university students was used and the average age of the participants was 20.74 years (SDage = 2.57) and 54.1% were women. For the Bergen Facebook Addiction Scale (BFAS) the questionnaire Fear of Missing Out (FoMO) was applied as a measure of contrast (r = .60). The internal structure was determined under the confirmatory factorial analysis (CFA), the equivalence of measurement was also evaluated by multigroup factor analysis models (CFA-MG) where levels of invariance were verified by sex, age and academic involvement. The relevant use of the alpha coefficient was corroborated by the implementation of restrictions in confirmatory models to evaluate tau-equivalence and parallel measures, where adequate results were obtained (α = .84). This version of the BFAS reports useful evidence for research into behavioral addictions due to its need to be included in batteries that assess addictions to social networks.
