Objective: To determine the measurement properties of PRECIOUS, a parent-reported measure of Quality of Care (QoC) for seriously ill children across care settings and illness trajectories. Study design and setting: Parents self-administered baseline and two-week follow-up surveys online. Exploratory Factor Analysis (EFA) was used to determine PRECIOUS's factor structure and select items. Internal consistency was evaluated with Cronbach's α, test-retest reliability with intraclass correlation coefficients (ICCs), and convergent validity with Spearman's correlations between PRECIOUS scales and subscales of Measure of Processes of Care (MPOC-20) and Quality of Children's Palliative Care Instrument (QCPCI). Results: Of 152 parents [108 (71%) mothers, 44 (29%) fathers] who completed the baseline survey, 123 (81%) completed follow-up. EFA grouped PRECIOUS into 5 scales: Collaborative and goal-concordant care (12 items), Caregiver support and respectful care (15 items), Access to financial and medical resources (5 items), Reducing caregiving stressors (9 items), and Hospitalization-specific processes (4 items). Root Mean Square Error of Approximation was 0.040 and Comparative Fit Index was 0.980. Cronbach's α ranged from 0.85 to 0.96. ICCs ranged from 0.72 to 0.86. Significant correlations with MPOC-20 and QCPCI confirmed convergent validity. The original 56-item tool was reduced to 45-items. Conclusion: PRECIOUS demonstrates satisfactory measurement properties for assessing QoC for seriously ill children.
