Pediatric psycho-oncology in Russia: Caregiver mental health and sleep outcomes on the oncology wards.

Objectives: Caregivers are at risk of poor sleep and elevated distress during their child's cancer treatment. Russia is currently underrepresented in the international psycho-oncology field, with no identified psychosocial standards of care, and limited or inconsistent psychological service provision, particularly for caregivers. This study aimed to determine the prevalence of Russian caregivers' psychological distress and identify factors associated with caregiver sleep duration when staying on the pediatric oncology ward.
