In recent years several instruments have been presented to evaluate these behaviors that urges for the adaptation to different contexts and populations. In this study we present the psychometric properties of the Bergen Facebook Addiction Scale (Andreassen et al., 2012) with Portuguese university students in two studies with samples of 442 and 196 participants to whom the instrument was applied with other measures of addition to Internet intensive use of Facebook adapted to Portuguese context. The results allow us to find good validity and internal consistency, as well as temporary stability of the instrument. They also allow us to finding gender differences in the two studies, a correlation with age and academic performance. The results are discussed based on the literature and future studies are suggested.spaAddictionFacebookPsychometric propertiesUniversity studentsjournal article10.21134/haaj.v18i1.37785041386405
