Table 7. Between-group effect sizes (Cohen's d) for primary and secondary outcomes. Outcome T1 (4 wks) T2 (8 wks) T3 (12 wks) Cognitive Anxiety 1.21 2.24 1.95 Somatic Anxiety 1.02 2.22 1.83 Self-Efficacy -0.82 -1.89 -1.67 Mindfulness (FFMQ) -0.76 -1.91 -1.74 T1 = week 4; T2 = week 8 post-intervention; T3 = week 12 follow-up. Positive Cohen's d values indicate a favorable outcome for the intervention group on anxiety outcomes (lower scores), whereas negative values indicate a favorable outcome for the intervention group on self-efficacy and mindfulness outcomes (higher scores).
