The main part of the article presents the results of most recent empirical study about the qualify of life for families in Slovenia that have a child with intellectual disabilities and other developmental disabilities. Using the FQOLS-2006 we analysed nine quality of life domains (Health, Financial Well-Being, Family Relationships, Support from Others, Support Services, Influence of Values, Careers, Leisure, Community Interaction) from the perspective of six measurement dimensions. The study also examines the differences among the measurement dimensions in the nine domains. The sample consisted of 44 families. We used descriptive statistics and inferential statistics (Friedman test). The Family Relationships domain had the highest average rating of all measured domains regarding the quality of family life.The results in the domain of Support from Others are not encouraging, in particular the domain of Support from Services. Families require powerful support programs of qualified professional teams as well as societal and political attention.
