Abstract
Objective
To adapt and validate the Ferrans and Powers Quality of Life Index for Brazilian pregnant women.
Methods
This is a methodological study. The Ferrans and Powers Quality of Life Index for pregnant women, Brazilian version, has 36 items and four domains. Content validity was performed by a committee of judges. In the validity stage, internal consistency, convergent and discriminant construct validity and dimensionality were tested. Significance level 5%.
Results
Five judges participated in a committee. The Content Validity Index was 0.94 and most items had a content validity coefficient per item above 0.80. A total of 280 pregnant women participated in the validity stage. Cronbach’s alpha was 0.94 for the total score, ranging from 0.78 to 0.89 between the domains. Pearson’s correlation between the Ferrans and Powers Quality of Life Index and the WHOQOL-Bref was positive and strong (0.79; p<0.001). Discriminant construct validity did not reveal statistically significant differences. Confirmatory factor analysis revealed that the four-domain model fits the model.
Conclusion
The Ferrans and Powers Quality of Life Index, adapted version, proved to be reliable and valid for use in pregnant women, proving to be a promising tool for health professionals and researchers to identify pregnant women’s quality of life.
