The Child-Adult Medical Procedure Interaction Scale-Revised: an assessment of validity.

Investigated the validity of the Child-Adult Medical Procedure Interaction Scale-Revised (CAMPIS-R) using multiple concurrent objective and subjective measures of child distress, approach-avoidance behavior, fear, pain, child cooperation, and parents' perceived ability to help their preschool children during routine immunizations. Parents', staffs', and children's behaviors in the treatment room were videotaped and coded. Results indicate that the validity of the CAMPIS-R codes of Child Coping and Distress, Parent Distress Promoting and Coping Promoting, and Staff Distress Promoting and Coping Promoting behavior were supported, with all significant correlations being in the predicted direction. An unanticipated finding was that the child, parent, and staff Neutral behaviors were inversely related to some measures of distress and positively related to some measures of coping. Interobserver reliability was high for each CAMPIS-R code.
