In spite of these limitations, the implications drawn from the
results of this study expand the understanding of smartphonerelated
addictive behavior and provide a diagnostic manual for
smartphone addiction. The SAS consists of 48 questions and is
grouped into six subscales, all weighted equally on a 6-point scale.
The six subscales’ scores are summed up to yield a total SAS score
with a 48–288 range, where a higher score indicates more serious
smartphone addiction. Finally, the SAS was presented as including
six factors and 33 items identified via factor analysis in Table S1.
Further studies should research on the correlation between
smartphone addiction and anxiety, depression, loneliness, low selfesteem,
impulse, and social maladjustment to verify the structural
model of the diagnostic system of smartphone addiction.
Moreover, it is necessary to develop a short form of SAS to
enhance its reliability and convenience. In short, this research
supplied the first SAS, which may serve as an opening for the
clinical diagnosis of smartphone addiction.
