SOUSA, Luís Manuel Mota de et al. Validation of the Brief Pain Inventory in Persons with Chronic Kidney Disease. Aquichan [online]. 2017, vol.17, n.1, pp.42-52. ISSN 1657-5997. https://doi.org/10.5294/aqui.2017.17.1.5.
Objective:
Verify the psychometric properties of the Portuguese version of the Brief Pain Inventory in persons with chronic kidney disease who are undergoing hemodialysis.
Method:
This is a methodological study. The selected sample is comprised of 171 persons with chronic kidney disease who experience pain for at least 24 hours and are undergoing hemodialysis at two clinics in Lisbon, Portugal. The data were collected between May and June 2015. The psychometric properties that were evaluated include validity (construct, convergent and discriminant), reliability (Cronbach's α) and stability (test-retest).
Results:
Information was obtained that adequately supports a bi-factor structure (pain interference and degree of pain severity), with reliability (α = 0.90 and α = 0.80, respectively) and stability. The measures registered correlate positively with the negative effect, and negatively, with measures of quality of life, which support concurrent validity. The existence of support for predictive validity was verified.
Conclusions:
The "pain severity" and "pain interference" measures obtained with the Brief Pain Inventory are valid and reproducible in persons with chronic kidney disease who experienced pain during the 24 hours before the questionnaire was used and the interview was conducted.
