Abstract
OBJECTIVES: to verify the construct validation of an instrument for evaluating care for people living with HIV in Primary Health Care. METHODS: methodological study carried out in 2021 with 260 health professionals in Recife, PE. Validation based on the internal structure was carried out at this stage using exploratory and confirmatory factor analysis, and validity based on item response theory. RESULTS: the validation determined the retention of five factors and 63 items. The instrument's internal consistency and quality of fit was 0.90, the Tukey-Lewis index was 0.915 and the comparative fit index was 0.918 in the confirmatory factor analysis. The indication for the absolute majority of items is adequate fit. CONCLUSIONS: the instrument has construct validity, making it possible to use it to evaluate the decentralization process and care for People Living with HIV in Primary Health Care.
