This randomized clinical trial aimed to compare the effectiveness of Mandala coloring and Twin Hearts Meditation in reducing exam anxiety among undergraduate nursing students. Participants were randomly assigned to either the Mandala coloring group or the Twin Hearts Meditation group. Both interventions were administered before a practical examination. Anxiety levels were measured before and after the intervention using the State-Trait Anxiety Inventory (STAI). The study evaluated which complementary and non-pharmacological intervention was more effective in reducing exam-related anxiety among nursing students.
