Animation-Based Video and Brochure-Based Education

This study was designed as a three-arm, parallel-group, randomized controlled trial to evaluate the effects of animation-based training versus brochure-based training before echocardiography on children's anxiety, fear, and physiological parameters. Research Hypotheses H1: Children aged 7-10 who receive animation-based educational videos prior to the echocardiography (ECHO) procedure will have lower levels of anxiety and fear compared to children receiving routine care. H2: Children aged 7-10 who receive brochure-based education before the ECHO procedure will have lower levels of anxiety and fear compared to children receiving routine care. H3: The effects of animation-based education and brochure-based education on children's anxiety and fear levels before the ECHO procedure differ. H4: In groups that received cartoon/video-based education and brochure-based education before the ECHO procedure, parents' satisfaction with nursing care is higher than in the routine care group.
