The present study sought to verify the initial evidence of internal structure validity and convergent validity of the Informal Caregiver Burden Assessment Questionnaire - short version (QASCI-VR) in family members of people with intellectual disabilities. The sample consisted of 185 caregivers of people with intellectual disabilities, users of a service provided by a non-governmental organization for assistance to people with disabilities, located in a Brazilian capital. For this, exploratory factor analysis, precision and external validity were performed. The results showed a two-dimensional internal structure of the adapted instrument, consisting of eleven items, with adequate precision indicators for factor Family Support and Self-Control (compound reliability = 0.80; α = 0.76 and ω = 0.76) and for factor Care Overload (Compound reliability = 0.81; α = 0.61 and ω = 0.66). Furthermore, evidence of convergent validity was observed between the adapted measure of the Informal Caregiver Burden Assessment Questionnaire - short version (QASCI-VR) and the Medical Outcomes Study Social Support Scale (MOS-SSS), and the Brazil Economic Classification Criteria (CCEB). Thus, the results show that the short adapted version of the instrument had adequate psychometric properties in the Brazilian sample and can be used in this context and population.
