The effect size was derived from the anxiety scores measured 30 minutes after the patients returned to the ward following angiography. sample size was increased to 64 participants, including 32 patients in the intervention group and 32 patients in the control group. Data will be collected using the Descriptive Characteristics Form, State Anxiety Inventory (SAI), Vital Signs Monitoring Form, Visual Analog Scale (VAS), and Patient Satisfaction Assessment Scale. The study procedure will be conducted as follows: Upon admission to the urology clinic for surgery, all participants will complete the Descriptive Characteristics Form, State Anxiety Inventory, and Vital Signs Monitoring Form before the surgical procedure.Patients admitted for TURP will be screened for eligibility by the research team. After obtaining written informed consent from eligible participants, the research team will notify an independent consultant, who will perform the random allocation and inform the principal investigator (GB) of each participant's group assignment.Participants assigned to the intervention group will be asked to select a mandala design from a coloring book and color it for 20 minutes.Participants in the control group will receive the hospital's routine preoperative care and standard clinical procedures.Following the intervention, all patients will be prepared for surgery and transferred to the operating room.After surgery, once the patients return to the ward and are settled in their beds, the State Anxiety Inventory, Vital Signs Monitoring Form, Visual Analog Scale, and Patient Satisfaction Assessment Scale will be administered.
