3.1 S-AI scores
There was a significant main effect of group (F (1, 40) = 13.40,p = 0.001, ηp 2 = 0.25), and the S-AI scores were significantly higher in the stress group than in the control group; the main effect of time was also significant (F (2, 80) = 17.37, p < 0.001,ηp 2 = 0.30), and the S-AI scores were significantly higher after the TSST (38.36 ± 11.53) than at baseline (31.76 ± 6.68) and after the N-back task (34 ± 9.53). There was a significant interaction between group and time (F (2, 80) = 12.91, p < 0 .001,ηp 2 = 0.24). Further analysis revealed that the S-AI of the stress group (45.71 ± 11.30) was significantly higher than that of the control group (31.00 ± 5.57) after the TSST (p < 0.001, d = 0.42).
