Translation and Validation of the Selfitis Behavior Scale for the Portuguese Population

Background: Excessive use of social media among young individuals can trigger obsessive behaviors, such as the obsessive compulsion to take selfies.Objective: To translate, culturally adapt, and validate the Selfitis Behavior Scale (SBS) among Portuguese higher education students.Methodology: Psychometric study in which the SBS underwent apparent validity assessment, internal consistency analysis, confirmatory factor analysis, measurement invariance testing, as well as convergent and discriminant validity assessment.Results: Confirmatory factor analysis of the original six-factor model revealed an adequate fit.Global internal consistency was high (Cronbach's and McDonald's = 0.94; CR = 0.97), with subscales ranging from 0.79 to 0.89.Evidence of convergent validity, discriminant validity, and invariance between groups with different selfie-taking frequencies was found.Statistically significant differences were observed between the groups, with higher scores in participants who reported taking selfies frequently. Conclusion:The Portuguese version of the SBS exhibited good psychometric properties, proving to be a valid and reliable instrument for assessing selfitis behavior among higher education students.
