  1. High-anxiety subgroup (SCAS scores ≥ 35), Low-anxiety (SCAS scores < 35) subgroup analysis: estimated mean score on the SCAS at each time point and estimated difference in change between the experimental groups according to a mixed effects model for repeated measures. Scores are presented in the form M (95% CI). SCAS Spence Children’s Anxiety Scale
