Abstract
OBJECTIVE To analyze evidence of the validity and reliability of a Brazilian Portuguese version of the Quality of Care Scale from the perspective of people with physical and intellectual disabilities.METHODS There were 162 people with physical disabilities and 156 with intellectual disabilities from Porto Alegre and metropolitan region, who participated in the study in 2008. Classical psychometrics was used to independently analyze the two samples. Hypotheses for evidence of criterion validity (concurrent type) were tested with the Mann-Whitney test for non-normal distributions. Principal components analysis was used to explore factorial models. Evidence of reliability was calculated with Cronbach alpha for the scales and subscales. Test-retest reliability was analyzed for individuals with intellectual disabilities through intra-class correlation coefficient and the Willcoxon test.RESULTS The principal components in the group with physical disabilities replicated the original model presented as a solution to the international project data. Evidence of discriminant validity and test-retest reliability was found.CONCLUSIONS The transcultural factor model found within the international sample project seems appropriate for the samples investigated in this study, especially the physical disabilities group. Depression, pain, satisfaction with life and disability may play a mediating role in the evaluation of quality of care. Additional research is needed to add to evidence of the validity of the instruments.
Highlights
Concern with the quality of care given in health services stems from the relationship between this construct and expectation and quality of life.[18]

The World Health Organization (WHO) understands that quality in a health system presupposes a constant concern with six fundamental dimensions: efficacy, efficiency, acceptance, accessibility, equality, and safety.[18]
Summary
Concern with the quality of care given in health services stems from the relationship between this construct and expectation and quality of life.[18]. It is estimated that more than one billion people in the world live with disabilities and approximately 200 million of those people have considerable functional difficulties.[19]. According to the United Nations Organization (UN),a 2/3 of the people with disabilities live in developing countries. This number increases continuously with population growth, wars and other forms of violence, inappropriate medical care, accidents, and increasing life expectancy. According to the UN, in 2010, 3.9% of the people in Brazil had disabilities, which represents 23.9% of the general population in that period.b Considering the people affected indirectly by the disability of someone close, more than half of the world population is affected by issues related to disability.a studies on QC received by people with disabilities have become important for public health
