[Psychometric validation in Spanish of the Brazilian short version of the Primary Care Assessment Tools-users questionnaire for the evaluation of the orientation of health systems towards primary care].

OBJECTIVE

To validate the Brazilian short version of the PCAT for adult patients in Spanish.

DESIGN

Analysis of secondary data from studies made to validate the extended version of the PCAT questionnaire.

LOCATION

City of Córdoba, Argentina. Primary health care.

PARTICIPANTS

The sample consisted of 46% of parents, whose children were enrolled in secondary education in three institutes in the city of Cordoba, and the remaining 54% were adult users of the National University of Cordoba Health Insurance.

MAIN MEASURES

Pearson's correlation coefficient comparing the extended and short versions. Goodness-of-fit indices in confirmatory factor analysis, composite reliability, average variance extracted, and Cronbach's alpha values, in order to assess the construct validity and the reliability of the short version.

RESULTS

The values of Pearson's correlation coefficient between this short version and the long version were high .818 (P<.001), implying a very good criterion validity. The indicators of good global adjustment to the confirmatory factor analysis were good. The value of composite reliability was good (.802), but under the variance media extracted: .3306, since 3 variables had weak factorials loads. The Cronbach's alpha was acceptable (.85).

CONCLUSIONS

The short version of the PCAT-users developed in Brazil showed an acceptable psychometric performance in Spanish as a quick assessment tool, in a comparative study with the extended version.
