The psychological well-being of the siblings of hospitalized children is at risk. This study examined the variables related to siblings' internalizing problems and personal growth during hospitalization from the perspectives of mothers and other main caregivers who temporarily assumed the main caregiver role to the siblings of hospitalized children in place of mothers in the period of children's hospitalization. A cross-sectional, exploratory survey conducted in Japan examined 113 mothers' and 90 other main caregivers' perspectives regarding the psychological state of 2- to 18-year-old siblings of hospitalized children. Mothers and/or other main caregivers of siblings during their brothers' or sisters' hospitalization completed the Child Behavior Checklist and the Siblings' Personal Growth Scale. Multiple linear regression analysis was performed with Child Behavior Checklist internalizing problems and total Siblings' Personal Growth Scale scores as dependent variables for mothers' and caregivers' perspectives. From mothers' perspectives, environmental factors that change with hospitalization affected siblings. From the perspectives of the other main caregivers, children's and families' demographic factors affected siblings' psychological state. Frequency of e-mail contact between mothers and siblings, explanation of the hospitalized child's condition, and hospital visitation rules ( F = 5.88, P = .001) explained 12.3% of variance in mothers' Siblings' Personal Growth Scale scores. Among other main caregivers, 11.6% of variance in the Child Behavior Checklist scores was explained by hospitalized children's birth order and main caregiver's prehospitalization residence ( F = 5.51, P = .006). Results suggest that the perceived variables related to siblings' psychological changes differ between mothers and other main caregivers.
