Abstract: Objective: To explore the application effects of McMaster model of family functioning among families with premature infants. Methods: Families with premature infants discharged from the neonatology department of a tertiary grade A children's hospital from May to November 2021 were recruited using convenience sampling method. They were randomly assigned into control group (n=39) and intervention group (n=41). The control group received routine family support, while the intervention group received a 12-week family support based on the McMaster model of family Functioning The scores of Family Assessment Device (FAD), physical development (length, weight, head circumference) and neuropsychological development (developmental quotient) of premature infants were compared between the two groups before and after intervention. Results: After the intervention, the score of FAD in the intervention group was significantly lower than that in the control group (P<0.05). The scores of communication, role, emotional response and total function in the intervention group were lower than those of the control group respectively (P<0.05). After intervention, the weight and length of premature infants in the intervention group were increased compared with those in the control group respectively (P<0.05). After intervention, the developmental quotient scores of premature infants in the intervention group were higher than those in the control group (P<0.05). Conclusion: The family support based on McMaster model of family functioning can effectively improve the overall level of family function, help the family play a better role, promote the length, weight and neuropsychological development of premature infants. It can be recommended for nurses to provide supports for families with premature infants.
