Methods
Cross-sectional study in children (7 to 17 years) with relapsed/refractory cancer and their caregivers, who spoke English, were not cognitively impaired, and had internet access. Parents were recruited through Facebook ads. Parents and children completed the Parent-Adolescent Communication Scale (PACS), a 20-item measure of communication quality, with openness and problem subscales. Spearman’s Rho coefficients assessed correlations between PACS scores and time since diagnosis/relapse.
