Children’s anxiety and induction compliance

SEPARATION
There was no significant difference in the baseline m-YPAS-SF scores at T0 between the control group and the intervention group (41.68 [31.26, 45.85] vs. 41.68 [37.51, 45.85], p = 0.859). The mean m-YPAS-SF score in the intervention group was significantly lower than that in the control group at T1, T2, and T3 (all p < 0.001). By using MMRM after adjusting m-YPAS scores at T0 as a covariate, the intervention effect in terms of the mYPAS-SF score was also significant over time (p < 0.001). The percentage of children with perfect induction compliance (ICC = 0) in the intervention group was higher than that in the control group [18.4% vs. 7.5%], and poor induction compliance (ICC>4) was lower (2.6% vs. 17.5%, p = 0.048) (Table 
Children’s anxiety and induction complianceNotes: mYPAS-SF: the modified Yale Preoperative Anxiety Scale-Short-Form; Compliance Scale: According to the child’s behavior at the time of placing the mask, their compliance during induction was classified as poor (ICC > 4], moderate (ICC = 1–4), and perfect (ICC = 0). T0 = baseline, in an ophthalmology outpatient clinic, before any intervention; T1 = in the preoperative waiting area; T2 = at the time of separation from parents, move to OR; T3 = at the time of anesthesia induction. P value calculation: Continuous variables were tested by two independent samples t-tests
