Tolerability and adherence
SIDE EFFECT
To measure adherence to the remote study schedule, we assessed the percentage of training and outcome sessions completed. Comparing between groups revealed no significant difference on the training adherence (Theta: 96.43% (SD: 0.08), Control: 97.12% (SD: 0.10); t = 0.20, p = 0.84, Cohen’s d = 0.08) or outcome measures (Theta: 91.67% (SD: 0.11), Control: 89.74 (SD: 0.16); t = -0.37 p = 0.72, Cohen’s d = 0.14). Notably, the tACS side effects reported were mild for all 11 categories (scale 0–10), and there was no significant difference between the groups for all 11 side effect metrics (Table Average side effects across all eight tACS sessions for the theta and control groups.Values in parentheses represent standard deviation of the mean.
