Animation-Based Education to Reduce Child and Parent Anxiety During Pediatric Stem Cell Transplantation (Cartoon-HSCT)

The goal of this clinical trial is to evaluate the effect of animation-based education on state anxiety levels of children and parents and on parental satisfaction with health care during the pediatric hematopoietic stem cell transplantation (HSCT) process. The main questions it aims to answer are: Does animation-based education reduce children's state anxiety before HSCT compared to standard verbal education? Does animation-based education reduce parental state anxiety and increase parental satisfaction with the care process? Researchers will compare children and parents who receive animation-based education with those who receive routine verbal education to see if the animation-based intervention leads to lower anxiety scores and higher satisfaction levels. Participants will: Watch a short age-appropriate animated video explaining the HSCT procedure in a positive and understandable way (intervention group), or receive standard verbal information (control group). Complete pre- and post-intervention questionnaires assessing child and parent state anxiety levels and parental satisfaction with care. The study includes children aged 4-10 years who are hospitalized for hematopoietic stem cell transplantation and their accompanying parents.
