Concurrent Validity of the SAS subscales
Partial correlation analysis was conducted by controlling the
level of education of each subscale and VAS of six features. The
results are shown in Table 3. Each couple was significantly related.
SAS Scores of the Participants
As shown in Table 1, there was a significant difference between
the high school level of education and the Master’s or doctoral
level of education (p= 0.013). A significant job difference between
a student and a professional was also found (p = 0.016). It was
interesting that in ‘‘self-reported smartphone addiction,’’ significant
differences were found between ‘‘agree’’ and ‘‘disagree’’ and
between ‘‘unsure’’ and ‘‘agree’’ (p,0.001).
