Effects of Preparatory Information on Anxiety and Treatment Adherence in Heart Surgery Patients

This study examines if giving extra information helps heart surgery patients reduce anxiety (worry or fear) and be more cooperative. Participants will watch a short 12-minute video twice before surgery to prepare for their stay in the Intensive Care Unit (ICU). The research compares anxiety and cooperation between those who watch the video and those who only get usual information.

• **Study Length:** Participants will view the video twice before surgery and will have anxiety measured before and after.
• **Who Can Join:** First-time heart surgery patients who understand Thai and are in stable condition.
• **Participation:** Participants will need to attend meetings and complete anxiety assessments.

Those interested can learn more at the heart surgery clinic or while admitted to the hospital. Researchers will meet with interested patients, and they will need to pass a mental test to join. Two experienced nurses will help conduct the study, ensuring fairness. The study requires about 24 participants in each group to see if the video makes a real difference. Data analysis will be kept private and deleted after two years.
