Randomized Clinical Trial of a Legacy Intervention for Quality of Life in Children with Advanced Cancer

Abstract

Background: Legacy-making (actions/behaviors aimed at being remembered) may be a significant component for quality of life (QOL) during advanced illness and end of life. Although legacy interventions have been tested in adults, the impact of legacy activities on QOL for children has yet to be clearly defined. Objective: This study examined the impact of our newly developed web-based legacy intervention on dimensions of QOL among children (7-17 years old) with advanced cancer. Design: This single-site randomized clinical trial (RCT) used a two-group waitlist control design. The legacy intervention guided children to create digital storyboards by directing them to answer legacy questions about themselves (personal characteristics, things they like to do, and connectedness with others) and upload photographs, video, and music. Setting/Subjects: Facebook advertisements recruited children (ages 7-17) with relapsed/refractory cancer and their parents from the United States. Child-parent dyads (N = 150) were randomized to the intervention or usual care group, and 97 dyads were included for analysis. Measurements: Children and parents completed the PedsQL Cancer Module preintervention (T1) and post-intervention (T2). Results: Although not statistically significant, legacy-making demonstrated small effects in child procedural anxiety and perceived physical appearance (Cohen's d 0.35-0.28) compared to the wait-list control group. Conclusions: This study contributes important discoveries, including support for the feasibility of a RCT web-based legacy intervention for children with advanced cancer. We did not find convincing evidence supporting the hypothesis that legacy-making improved child dimensions of QOL across time. Overall, this is a null study that warrants discussion on possible reasons for limited findings. Future legacy intervention research is needed using qualitative and quantitative methods, as well as child and parent reports, to determine how such services may improve dimensions of QOL for pediatric palliative care populations.
