Tradução e validação da selfitis behavior scale para a população portuguesa

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 α and McDonald’s ω = 0.94; CR = 0.97), with subscales ranging from 0.79 to 0.89. Evidence of convergent validity, discriminant validity, and invariance be- tween 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.
