This study was done to develop a model which explains factors influencing caring behavior of mothers who have children with disabilities, and to verify the appropriateness of the model and the relationship among variables.

The participants in the research were the mothers who had a 3 to 12 yr-old children with disabilities. The data were collected from 451 mothers through self-reported questionnaires from July 14 to 31, 2008. A total of the 371 data sets were analyzed using SPSS/WIN 11.5 and AMOS 5.0 version.

The children's behavior characteristics, social support, objective burden and parenting self-esteem had an impact on the mothers' caring behavior. Especially, parenting self-esteem including parenting satisfaction and self-efficacy was the most influential factor. These variables explained 77% of the mothers' caring behavior for these children.

The results suggest that some strategies for promoting mothers' parenting self-esteem focused on parenting satisfaction and self-efficacy should be developed in order to help mothers in caring for their child who is disabled.
