ABSTRACT
BACKGROUND:
Vascular access (VA) is a central condition for hemodialysis (HD). Screening patients' views regarding their VA is a significant end point for improving the quality of care. The Short-form Vascular Access Questionnaire (SF-VAQ) is a specific questionnaire to assess patients' satisfaction levels regarding their VA.PURPOSE:
This study aims to develop the Portuguese version of the SF-VAQ and assess its psychometric properties.METHODS:
A forward and back translation was used. A multicentric study was conducted with 156 patients undergoing hemodialysis to psychometric testing. Reliability (internal consistency and test-retest) was assessed using Cronbach's alpha and Intraclass Correlation Coefficient. A construct validity test was conducted using factor analysis. The convergent validity was calculated using the correlation coefficient.RESULTS:
An obtained Cronbach's alpha of 0.77 indicates good internal consistency. The test-retest reliability was established using the Intraclass Correlation Coefficient (ICC) of 0.771. The four sub-scales proposed by the instrument's designer were confirmed, which together accounted for 53% of the variance. The correlation with the Visual Analogue Scale was r = 0.895 (p < 0.001), confirming the convergent validity.CONCLUSION:
The Portuguese version of the SF-VAQ is a valid and reliable instrument with good psychometric properties to be implemented to promote an evaluation of VA satisfaction in HD patients and improve patient care.
