Mandala Coloring and Its Effect on Anxiety and Depression Before Open Heart Surgery

Eight pre-selected mandala drawings will be printed on separate A4 (21.0 cm × 29.7 cm) papers. After the patients are admitted to the hospital for the surgery process, the patients in the experimental group will be provided with at least 2 hours of mandala coloring per day until the day of their surgery. No intervention will be applied to the control group patients. Studies examining the effect of mandala coloring on reducing psychological symptoms have reported that using a circularly designed pattern in the mandala template, instead of a square design, has a greater effect on symptom management. Therefore, a circular-shaped mandala template will be used. Each participant will be provided with mandala coloring sheets and 12 colored pencils (red, orange, yellow, pink, light green, green, sky blue, blue, purple, brown, reddish-brown, and black) by the researcher.
