The aim of the present study was to create a short and valid questionnaire: the Multidimensional Facebook Intensity Scale (MFIS). In Study 1 (N=512), we used exploratory structural equation modeling to explore the basic dimensions of everyday Facebook use. The results suggested four factors: persistence, boredom, overuse, and self-expression. The MFIS also had good reliability in terms of internal consistency and temporal stability. In Study 2 (N=566), confirmatory factor analysis was conducted in order to assess the factor structure revealed in the previous study. The four-factor first-order and the second order model appeared to be adequate contrasting to the one factor model. Based on target coefficient the four-factor second-order model appears to be the most adequate. In Study 3 (N=531), the convergent validity of the MFIS was examined in relation to Facebook addiction, Facebook passion, Online Sociability and different personality dimensions. The MFIS can predict Facebook-related activities as liking and posting better than previous Facebook scales. The results suggest that this questionnaire is able to reliably differentiate between different aspects of Facebook use intensity. •Facebook intensity was measured by persistence, self-expression, boredom and overuse.•The scale had good factor structure, internal consistency and temporal stability.•Good convergent validity was found with BFI and previous Facebook scales.•The average monetary value of Facebook for Hungarian users is 5284 USD.
