Note. Values are Cohen’s d effect size estimates derived from between-group (treatment vs. control) comparisons at post-treatment time points.
a
Study included multiple control groups; effect size derived from CBT-I/usual care comparison
b
Study included multiple control groups; effect size derived from Hybrid/ wait-list control comparison
