Hospital clowns are widely used in pediatric settings. However, the field of pain and pain experience in children is complex and multifaceted. Therefore, the aim of this study was to expand knowledge on the impact and influence of hospital clowns on 4 to 15-year-old children’s experiences of managing painful procedures and conditions. A convergent mixed method study was conducted integrating findings from three individual studies: a prospective non-blinded study and two focused ethnographic studies. The findings illuminated a child—clown interaction characterized by a close relationship evolving during a continuous, mutually focused attention, conceptualized as WE. This WE represent a responsive interaction between child and clown, which supported the child during the procedures, and generated three integrated findings: an age-differentiated approach; understanding the child’s condition; and previous experiences as a part of the child’s history. The WE approach strengthened the child’s competences and ability to manage during painful procedures.
