Background: Rates of sleep disturbances vary widely across pediatric cancer studies, partly due to differences in measurement tools. Patient-reported outcomes measurement information system (PROMIS) offers a rigorously developed, well-validated pair of pediatric sleep health instruments needed to advance sleep research and clinical practice in pediatric cancer. The current study evaluated the clinical validity of PROMIS pediatric sleep scales (sleep disturbances [SD] and sleep-related impairment [SRI]) among children in active cancer treatment. Procedure: Caregiver-patient dyads were enrolled during cancer treatment in 2-12 months after diagnosis: 45 children (ages 8-17 years) and 102 caregivers of children (ages 5-17 years) completed PROMIS SD and SRI 8-item short form self-report or caregiver-proxy scales, and caregivers reported the prior week's cancer treatments and blood counts. Results: Both scales demonstrated strong internal consistency reliability across reporters. SD and SRI were higher than the PROMIS general population calibration sample for caregivers and patients. Oncology caregivers reported lower SD and SRI than sleep clinic caregivers, but oncology patients were similar to sleep clinic patients. Convergent validity was evidenced through moderate correlations between scales by reporter and both scales being significantly higher in patients taking medications for sleep. There were no significant differences in SD or SRI by diagnostic group, receiving radiation, or having low blood counts. Conclusion: The PROMIS SD and SRI short forms are promising measures for pediatric oncology, demonstrating strong internal consistency reliability and multiple indications of clinical validity. Although groups did not differ based on treatment variables, results suggest the need for universal screening for sleep problems during pediatric cancer treatment.
