Preprocedural Video Education for Bronchoscopy Anxiety

The goal of this clinical trial is to learn whether preprocedural video education can reduce anxiety in adult patients who are scheduled to undergo bronchoscopy under general anesthesia. It will compare video-based education with standard verbal education. The main questions it aims to answer are: Does video education reduce preprocedural anxiety, as measured by the Amsterdam Preoperative Anxiety and Information Scale (APAIS), in patients undergoing bronchoscopy under general anesthesia? Researchers will compare patients who receive audiovisual education with those who receive standard verbal education to see whether video education provides greater anxiety reduction before bronchoscopy under general anesthesia. Participants will: 1. Complete an APAIS questionnaire before receiving preprocedural education 2. Receive either video-based education using a tablet or standard verbal education with a question-and-answer session 3. Complete another APAIS questionnaire immediately after the education session
