Anxiety reduction in children receiving medical care: developmental considerations.

The present investigation examined the importance of considering age-related conceptual abilities when designing preparation interventions for hospitalization and medical procedures. Forty-eight children, ages 3-5 years and 7-10 years, viewed videotaped information about an upcoming medical procedure. The children were assigned to one of three treatment conditions: control, developmentally appropriate information, developmentally advanced information. Results suggest that information which is designed to match the age-related conceptual abilities of the recipient more effectively reduces anxiety and increases cooperation. Implications for future research evaluating efficacy of preparation strategies are noted.
