Within group mean values (for pre- and post measures) are reported with SD in parenthesis. Effect sizes for within group longitudinal changes are reported as Hedges G, with lower and upper bound for 95% CI (bootstrapped, n = 10000) in parentheses. Group by time interactions are tested using repeated measure ANOVA, where the F statistics are reported with the significance level in parenthesis. Effect sizes are specified using eta-squared, with the lower and upper bound in parentheses. Significant (unc) effects are in bold. Groups did not significantly differ with regard to age [t(45) = 0.92, p = 0.36] or sex [χ2(1) = 0.045 p = 0.83].
