Official title
The Impact of Conversational Approaches in Pediatric Robot-Mediated Interventions on Children's Responses in Hospital Settings: A Comparative Study of Rule-Based vs. LLM-Based Systems
Overview
This study examines how different robot dialogue systems (rule-based vs. large language model-based) and content types (emotional support vs. safety education) affect pediatric patients' responses during hospital-based robot-mediated interventions. Approximately 60 pediatric patients aged 2-9 years will be randomly assigned to interact with a social robot (LIKU) using either rule-based or LLM-based dialogue. Each child will participate in two activity sessions (emotional content and safety content) in randomized order. Primary outcomes include child engagement, emotional responses, robot perception, and activity preferences, assessed through standardized questionnaires (UEQ, Godspeed), child interviews, and behavioral observations. Additionally, 5 experts will evaluate content appropriateness and safety. This pilot study aims to provide foundational data for developing personalized pediatric robot programs in hospital settings, optimizing both dialogue approaches and content design based on individual child characteristics.
Interventions
- Behavioral Robot-Mediated Emotional Support Activity
10-15 minute structured activity focusing on emotional recognition, expression, and regulation through storytelling, discussion, and artistic activities (drawing, physical expression) with the LIKU social robot - Behavioral Robot-Mediated Safety Education Activity
10-15 minute structured activity focusing on safety awareness and emergency response behaviors through educational videos, discussions, and hands-on activities (crafts, physical practice) with the LIKU social robot
Primary outcome measures
- Child Engagement Level [Time frame: Immediately following each intervention session (assessed within 1 hour post-session)]
- User Experience [Time frame: Immediately following each intervention session (approximately 5 minutes post-session)]
- Robot Perception [Time frame: Immediately following each intervention session (approximately 5 minutes post-session)]
Secondary outcome measures (4)
- Content Appropriateness [Time frame: Within 2 weeks of session completion via video review]
- Activity Preference [Time frame: Immediately following completion of both intervention sessions (approximately 5 minutes)]
- Content Comprehension [Time frame: Immediately following each intervention session (approximately 3 minutes)]
- Robot Relationship Quality [Time frame: Immediately following intervention sessions (approximately 5 minutes)]
