Abstract

CONRAD, Carolina et al. Translation into Brazilian Portuguese, cultural adaptation and validation of the Prosthesis Evaluation Questionnaire. J. vasc. bras. [online]. 2015, vol.14, n.2, pp.110-114. ISSN 1677-5449.  http://dx.doi.org/10.1590/1677-5449.0038.

BACKGROUND:

Quality of life has been one of the main issues for patients with a chronic condition.

OBJECTIVE:

To translate, adapt and validate a Brazilian Portuguese version of the Prosthesis Evaluation Questionnaire (PEQ).

METHODS:

The questionnaire was translated into Portuguese, back translated into English, and cross-culturally adapted to the Brazilian Population. Sixty-five transtibial unilateral amputees were recruited. The sample comprised 45 men and 20 women with a mean age of 44 years, 47 with traumatic amputations, 14 with vascular dysfunction and 4 with other reasons for amputation, and all of them fitted with prostheses. Patients were interviewed twice, at baseline and again after 15 days. The Brazilian Portuguese version of the SF-36 (a generic Quality of Life outcome measure) and the FIM (a Functional Independence Measure) were also administered.

RESULTS:

The internal consistency of the nine PEQ scales was tested by computing Cronbach's Alpha coefficients (0.65 - 0.89: high values). Student's t test coefficients were used for interobserver evaluation (0.35 to 084: reliable values with one exception- the Residual Limb Health scale), and Intraclass Correlation Coefficients (ICC), which ranged from 0.65 to 0.92: reliable values. Student's t test coefficients and ICCs were also used for intraobserver evaluation (0.42 to 0.83, except the Residual Limb Health scale and 0.80 to 0.94, respectively: reliable values). Correlations between PEQ, SF-36 and FIM were tested using Pearson's correlation coefficients, which were not statistically significant (p > 0, 01).

CONCLUSION:

The Brazilian-Portuguese version of the PEQ has high internal consistency and is a reliable quality of life measure for use in amputee patients, but is not associated with the SF-36 or FIM.
