Table 1 showing the differences SAS scores between groups. T-test was used to produce a p-value. The analysis shows that male students, junior students, students with poorer backgrounds and less social support get significantly higher scores. (Family economy: Rich = annual household income over 500,000 Yuan; Common = annual household income less than 500,000 Yuan but more than 200,000 Yuan; Poor = annual household income less than 200,000 Yuan.)

P-value <0.05 were considered statistically significant.
