Animation-assisted psychological intervention in pediatric care: mechanisms, clinical applications, and emerging evidence

Children frequently experience fear, anxiety, and pain during medical encounters, and this distress can lead to poor cooperation, longer procedures, and lasting avoidance of care. Animation, delivered as cartoons, preparation films, applications, serious games, and virtual reality (VR) scenes, has become one of the most widely deployed non-pharmacological adjuncts in pediatric settings because it is inexpensive, non-invasive, and easily standardized. Drawing on a structured search of six databases through July 2026, this mini-review synthesizes randomized and meta-analytic evidence across perioperative anxiety, procedural pain, pediatric dentistry, chronic-disease self-management, and mental health promotion. It organizes the evidence around five psychological pathways: attentional competition, observational learning, exposure and inhibitory learning, narrative-affective processing, and self-efficacy. Additionally, it examines a sixth, non-psychological use in which animation is used to provide therapeutic visual stimulation. Evidence supports moderate short-term benefits for anticipatory anxiety and for needle- and dentistry-related distress, with weaker and less consistent effects for high-intensity procedures and physiological outcomes. We argue that the field's core issue is conceptual rather than empirical: animation refers to a delivery medium, not a treatment, and trials have compared media rather than mechanisms. This obscures three unresolved problems: discordance between self-reported and autonomic outcomes; an untheorized moderating role of the developmental stage; and a theoretical tension between distraction, which withdraws attention from the feared stimulus, and exposure, which requires engagement with it. Mechanism-matched comparators, core outcome sets, developmentally stratified designs, transparent intervention reporting, and follow-up across repeated procedures are prerequisites for cumulative progress.
