Abstract

This study compared changes in mental well-being following mindfulness-based yoga, transcranial direct current stimulation (tDCS), and their combination among students at Torbat-e Jam Faculty of Medical Sciences. This pretest–posttest study included three active intervention groups. Forty-five male students aged 18–24 years were allocated to mindfulness-based yoga, active tDCS, or combined yoga plus active tDCS (n=15 per group). Each group completed 12 sessions over 6 weeks. Mental well-being was measured using the Magyar-Moe and Keyes scale. Paired t tests, analysis of covariance, and Bonferroni-adjusted pairwise comparisons were performed in SPSS version 27. No no-intervention control or sham-tDCS group was included. Mental well-being scores increased from pretest to posttest in all three active groups (p<0.05). ANCOVA controlling for baseline scores indicated an overall between-group difference (p=0.020; η²=0.180), with a higher adjusted mean in the combined group. In the absence of a control and sham condition, these findings cannot establish the absolute efficacy of the interventions. The combined intervention was associated with a higher adjusted posttest mental well-being score than either active intervention alone. The finding is preliminary and requires confirmation in adequately powered, sham-controlled randomized trials with blinded assessment and follow-up.
