Objective: To examine the self-assessment of the impact of parental care for a child with developmental disabilities on the family's quality of life, and to examine the impact of sociodemographic characteristics on the quality of life of families of children with developmental disabilities. Methods: the research was conducted according to the principle of a cross-sectional study, using an anonymous validated questionnaire to assess the quality of life of parents of children with developmental disabilities and a sociodemographic questionnaire. The respondents were parents of children with developmental disabilities. Results: The self-assessed quality of life of families of children with developmental disabilities is 45.1, which indicates that parents are mostly dissatisfied with their quality of life, as the range of points is 0-100. With regard to the sociodemographic characteristics of the test participants, no statistically significant difference was found in the respondents' answers. Conclusion: the parents of this study are mostly dissatisfied with their quality of life. It is necessary to ensure support for parents of children with developmental disabilities in all counties and major cities through the work of associations. Institutions for work with children with developmental disabilities function through various projects and workshops, while work with parents is neglected due to the exclusive focus on children. It is important to remember that the family is the basis for the development and improvement of the child, so it is necessary to extend the work to the whole family.
