Assessing Problematic Facebook Use: Psychometric Properties of the Polish Version of Facebook Intrusion Questionnaire
Abstract BackgroundFacebook is used for work, entertainment and communication. However, there is potential for problematic or addictive use which can cause significant mental and physical health problems. The Facebook Intrusion Questionnaire (FIQ; Elphinston & Noller, 2011) is one of the most widely used measures of problematic Facebook use. However, no previous study has validated this measure in a Polish population. MethodsThe study aims to validate the Polish adaptation of FIQ. Five large samples of Polish Facebook users (N = 12,753; M age = 21 years; 66% female) were used to examine the psychometric properties of the Polish version of the FIQ. ResultsAn exploratory and confirmatory factor analysis provided support for a unidimensional factor structure (χ2(16) = 199.53, p< 0.001; RMSEA = 0.042; SRMR = 0.022; CFI = 0.950). Item response theory showed that the adapted FIQ items had adequate discrimination and information levels. ConclusionThe Polish version of the FIQ showed good internal consistency and adequate construct validity. Overall, the findings suggest that the FIQ is a reliable and valid measure for use in the Polish population.
