Validity and Reliability of the Hungarian Version of Aberdeen Varicose Vein Questionnaire

Abstract

Purpose: The aim of our study was to translate the Aberdeen Varicose Vein Questionnaire (AVVQ) into Hungarian, and to investigate the validity and reliability of the Hungarian AVVQ, as well as to assess the health-related quality of life in patients with varicose veins of the leg. Methods: 374 adults participated in this study who were divided into two groups (varicose vein, healthy). We analyzed internal consistency, convergent validity (using the 36-Item Short Form Survey, SF-36), repeatability, and intra-class correlation coefficient of the Hungarian AVVQ. Regarding discriminant validity, we determined the scores of the Hungarian AVVQ in both groups using the Mann-Whitney U-test. Results: The Cronbach-alpha value was 0.890, while the correlation coefficient was R = 1.000. According to the results of the convergent validation, the scores of pain and dysfunction moderately correlated with some scores of the SF-36. The score of cosmetic appearance had a relationship with many scores of the SF-36. We registered a significant relationship between the score of extent of varicosity and some scores of the SF-36. There was significant correlation between the score of complications and numerous scores of the SF-36 (physical functioning, role limitations due to physical health, pain and general health). The score of pain and dysfunction, cosmetic appearance, extent of varicosity, complications and total score of the Hungarian AVVQ showed a significant difference between both groups. Conclusions: The Hungarian AVVQ was a reliable and a valid tool to assess the health-related quality of life among patients with varicose veins and was a useful tool to justify the further treatment of the patients.

Translation and adaptation to Spanish of Aberdeen varicose veins questionnaire

“…The goal of the study is to determine the feasibility and reliability of the Spanish-translated AVVQ in the population. The features of the AVVQ were similar to other samples, 83% of patients were women, 76% on the sample described by Garrat, 5 69% on the Dutch sample, 8 84% on the varicose group of the Hungarian sample, and 9 87.9% on the Brazilian sample. 10 Mean age was also similar, about 45–55 years in all samples.…”

“…The internal consistency with a Cronbach’s alpha of 0.71 is comparable to the one obtained by Garrat on the UK sample and Klem on the Dutch sample and the Persian sample recorded by Neamatshahi (0.72, 0.76, and 0.71, respectively), and the Hungarian sample showed a Cronbach’s alpha of 0.890. 5,8,9,11 Cronbach’s alpha value on the Brazilian sample was lower than reported before (0.54), although the internal consistency for the domains recorded was acceptable. 10…”

“…10 Mean age was also similar, about 45-55 years in all samples. 5,[8][9][10][11] The Spanish sample showed four questions with floor effects. On the other hand, two questions showed ceiling effects as indicated on results.…”
