Propiedades psicométricas del Smartphone Application-Based Addiction Scale (SABAS) en universitarios peruanos

The Smartphone Application-Based Addiction Scale (SABAS) is a brief tool that assesses the level of addiction exposure to smartphones. The purpose of the study is to examine the internal structure and reliability of this scale, applied in university students in Lima, having a sample of 463 university students, aged between 18 and 43 years (M=20.04; SD=3.29). The results show acceptable internal consistency indicators (α= 0.84; ω= 0.84). In the fit indices of the confirmatory factor model it revealed that the scale is unifactorial, showing adequate fit indices (χ2/df=3.64, RMSEA = 0.076 [CI90%: 0.049 - 0.104], SRMR = 0.038, CFI = 0.995 and TLI = 0.992). It also showed positive and weak correlations with anxiety and depression symptoms on the PHQ-4 scale. The findings support the usefulness of the SABAS as a screening tool to assess smartphone addiction in the Lima university context.
