Psychometric properties of the smartphone addiction scale-short version (SAS-SV) in Honduran university students

Problematic smartphone use (PSU) is a global issue associated with numerousadverse outcomes, especially among young people. One of the most widely usedinstruments to evaluate PSU is the Smartphone Addiction Scale-Short Version(SAS-SV). This study examined the psychometric properties of the Spanish versionof the SAS-SV, including factorial validity, convergent validity, divergent validity, andreliability. The final sample comprised 530 students from a university in Honduras.Confirmatory factor analysis provided evidence supporting the validity of the instrument'sinternal structure. Reliability was estimated using McDonald's omega andCronbach's alpha coefficients. Convergent validity was assessed through correlationswith problematic Internet use, depression, anxiety, and stress. Measurement invariancetests were conducted across sex and age categories. The results indicated thatthe SAS-SV adequately fits a one-dimensional, reliable model and demonstratedmeasurement equivalence across groups of sex and age. Finally, the SAS-SVdemonstrated a strong correlation with problematic Internet use, depression, anxiety,and stress. These findings support the SAS-SV as a valid and reliable instrument forexamining PSU among university students in Honduras.
