Validação do instrumento de avaliação da atenção primária à saúde: PCATool-Brasil adultos

Objective: to translate and adapt the PCATool version for adult users to the Brazilian context and assess its validity and reliability. Methods: We conducted a cross-sectional study of 2404 adult users living in areas covered from public services Primary Care in Porto Alegre, and users of a self- management plan. We performed translation, reverse translation and adaptation of the instrument as well as its assessment in respect of content validity, factorial validity and reliability. Results: In the factor analysis were considered 12 factors that explained 50.83% of the total variation. In this way were recognized the attributes of Primary Care: access - accessibility and utilization; longitudinality; coordination - coordination of care and systems of information; comprehensiveness - services available and services provided; family orientation; and community orientation. In terms of internal consistency the values of Cronbach’s alpha ranged from 0.15 to 0.90. The stability over time was not observed for coordination of care (p<0.05), coordination information of system (p<0.05) and comprehensiveness of services provided (p<0.05). The scaling success rate was close to 100% for all attributes, except to coordination of information system. Conclusions: the results indicated that the PCATool-Brazil has adequate validity and reliability, and it can act as a national instrument for the assessment of Primary Care from the perspective of adult users.
