Objective: to translate, adapt, and identify the psychometric properties of the Selfitis Behavior Scale (SBS). Methods: online study conducted with 261 Brazilian adolescents. The translation and cross-cultural adaptation process followed international guidelines, resulting in an adequate scale with face, content and construct validity. Results: The five factors explained 78.2% of the total variance. Confirmatory factor analysis (structural equation model for latent variables) showed an adequate fit of the five-factor model with χ2= 2.42 p=0.001, GFI=0.92, AGFI= 0.89, NNFI= 0.92, TLI= 0.96, CFI= 0.93, RMSEA= 0.041. All factor loadings were statistically different from zero (0; t >1.96, p<0.05). The total internal consistency value by Cronbach's alpha and McDonald's omega was above 0.80 and the internal consistencies of each factor were above 0.79. Conclusion: This is the first Brazilian study to evaluate the psychometric properties of a selfie scale. The SBS proved to be a reliable and valid instrument to assess selfie behavior.
