Limitations
There are some limitations in the study. First, data were collected in three children’s hospitals in Shanghai, Suzhou and Chongqing, China that are all big cities. Secondly, parents of children with leukemia account for majority of the sample. As such, the generalizability of our findings may be limited. Finally, after the diagnosis of their children, parents’ caregiving ability changes across the children’s disease treatment period. The present study is a cross-sectional study and unable to speculate the trajectory of parents’ caregiving ability development. Therefore, a longitudinal study is needed to explore the developmental trend of parents’ caregiving ability in the future.
