ABSTRACT
Objective:To explore the mediating effect of social support between anticipatory grief and sleep disorder of parents with acute leukemia children.Methods:By convenient sampling method, a total of 193 acute leukemia children and parents enrolled at Children`s hospital of Nanjing Medical University from January 2020 to August 2021 were enrolled as the research objects, the Pittsburgh Sleep Quality Index, Anticipatory Grief Scale and Perceived Social Support Scale were used for investigation. A structural equation model was established to evaluate the mediating effect of social support on anticipatory grief and sleep disorder.Results:The scores of Pittsburgh Sleep Quality Index, Anticipatory Grief Scale and Perceived Social Support Scale were 8.12 ± 4.95, 75.38 ± 13.91 and 62.09 ± 8.03 in parents with acute leukemia children, each demension scores and total scores of Pittsburgh Sleep Quality Index were positively correlated with Anticipatory Grief Scale, and negatively correlated with Perceived Social Support Scale ( r values were -0.184 - 0.916, all P<0.01). Anticipatory grief had a significantly indirect effect on the sleep disorder of parents with acute leukemia children through social support, which showed that the mediating effect of social support accounted for 79.6% of the total effect. Conclusions:Social support plays a mediating role in the relationship between anticipatory grief and sleep disorder, nurses can alleviate anticipatory grief and improve sleep disorder by promoting the levels of social support of parents with acute leukemia children.
