Effects of a Pretend Play Intervention on Health-Related Quality of Life in Children With Cancer: A Swedish-German Study.

Background: Cancer diagnosis can lead to massive physical, emotional, and social burdens on children and their families. Although children have the right to be informed and participate in their care, research shows that children's views are often not considered in care situations. Thus, it is essential to strengthen children's communication and self-efficacy (SE) to convey desires and needs. The present study explores whether a play intervention is associated with improved health-related quality of life (HrQoL) and SE for communication in care situations. We hypothesize that HrQoL and SE for communication will increase from the beginning to after the pretend play intervention. Methods: Children with cancer from Germany and Sweden were enrolled. The pretend play intervention consisted of six to 10 play sessions. A heterogenic selection of questionnaires was used to measure children's HrQoL and SE before the first pretend play session and after the last play intervention. Results: Nineteen families were included in the presented analyses, including 14 self-reports of children and 19 proxy reports of parents. We found improvements in child-reported communication, and emotional and psychosocial well-being using generic and cancer-specific HrQoL measurements. Further, children's SE in care situations improved during the play intervention. Parents also reported minor improvements in the physical dimensions in both generic and chronic-generic HrQoL, along with improvements in independence. Discussion: Overall, the cancer-specific pretend play intervention offers young children with cancer a secure environment and can contribute to their well-being, and communication skills, during or after cancer treatment.
