Social Robot Interaction on Fear and Pain Levels in Children

The goal of this clinical trial is to compare the effectiveness of social robot interaction and digital game-based distraction in reducing fear and pain during venous blood sampling in children aged 4-12 years with chronic diseases. The main questions it aims to answer are: * Does social robot interaction reduce procedural fear and pain more effectively than standard care during venous blood sampling? * Does social robot interaction provide greater emotional recovery after the procedure compared with digital game-based distraction and standard care? Researchers will compare a social robot intervention group, a digital game-based distraction group, and a standard care group to determine their effects on children's fear and pain levels before, during, and after venous blood sampling. Participants will: * Be randomly assigned to one of three groups: social robot, digital game, or standard care. * Complete fear and pain assessments 5 minutes before, during, and 5 minutes after the venous blood sampling procedure. * Interact with a social robot or play a digital game before and during the procedure if assigned to one of the intervention groups. * Receive routine clinical care if assigned to the standard care group. The study aims to provide evidence on the effectiveness of technology-based distraction methods for reducing procedural distress and improving the procedural experience of children undergoing venous blood sampling.
