Abstract: Objective To explore the effect of family mission intervention on family function and parental self-efficacy in children with malignant tumor. Methods 58 children with malignant tumor from 4 tertiary general hospitals in Tangshan city were included. Their parents were divided into control group (n=28) and intervention group (n=30). Both groups received routine treatment and nursing, while the intervention group received family mission intervention in addition. They were evaluated with Feetham Family Functioning Survey (FFFS) and the Self-Efficacy for Parenting Tasks Index-Toddler Scale (SEPTI) before and after intervention. Results After intervention, the total FFFS score (1.01±0.55), family and individual relationship score (0.79±0.64), and family and social relations score (1.21±0.92) were lower in the intervention group than in the control group (P<0.05). The scores of limit/constraint (4.19±0.55), game (4.09±0.32), and education (4.17± 0.78) of SEPTI were higher in the intervention group than in the control group (P<0.05). Conclusion Family mission intervention can improve the family function of children with malignant tumor, and improve the parents' self-efficacy.
