Abstract

The article shows the development and validation process of the Ferrans & Powers Quality of Life Index - Wound Version (FPQLI-WV) to be applied in people with different types of acute and chronic wounds. This methodological study was developed using theoretical, empirical and analytical procedures. Results showed that the instrument obtained satisfactory internal consistency and stability; and also confirmed content, concurrent (your satisfaction item) and convergent validities (WHOQOL-Bref), besides its discriminatory validity according to wound number and duration, pain intensity and age. Confirmatory factor analysis suggested FPQLI-WV showed reasonably fit to the original instrument model. In conclusion, FPQLI-WV showed to be reliable and valid for the most important wound patients' quality of life aspects such as health and the psychological and spiritual domains.
