Note. The table shows differences and effect sizes for entire sample from pre- to post-test on all outcome measures using repeated measures analysis of variance. SD = standard deviation; F = F statistic; df_between = degrees of freedom between groups; df_within = degrees of freedom within groups;

^*p < 0.05;

^**p < 0.01;

AAT = Approach-Avoidance Task; LSAS = Liebowitz Social Anxiety Scale; SPIN = Social Phobia Inventory; BDI-II = Beck Depression Inventory-II; IPSM-29 = Interpersonal Sensitivity Measure, 29-item version; BAT = behavioral approach test; Latency = time taken to begin task; Duration = time spent engaging in task; STAI-B = 8-item State-Trait Anxiety Inventory, state version. Cohen’s d (estimate of effect size) was calculated using the formula d = Mean₁−Mean₂/√[(SD₁² + SD₂²)/2], as outlined in Dunlap et al., 1996.
