Estimated means at baseline and post-intervention for the PHQ-9 (A) and GAD-7 (B). Digital CBT was associated with significant reductions in scores on the PHQ-9 (β = 3.34, SE = 0.16, 95% CI [3.03, 3.65], p < 0.001, Cohen’s d = 0.85) and GAD-7 (β = 3.64, SE = 0.15, 95% CI [3.36, 3.93], p < 0.001, Cohen’s d = 0.99)
