“…This was based on power calculations to assure reliable data. Our data are in accordance with earlier studies of other language versions of VISA‐A (Silbernagel et al., ; de Knikker et al., ; Maffulli et al., ; Lohrer & Nauck, ; Dogramaci et al., ). Together, our joint results help toward launching VISA‐A as a standard tool in the assessment of AT.…”

“…In order to use VISA-A for non-English-speaking patients, a translation and cultural adaptation of the questionnaire is needed, together with validity and reliability testing. The VISA-A questionnaire has been translated into several languages: Swedish, Italian, Dutch, German and Turkish, and is shown to be a both reliable and valid instrument in these languages (Silbernagel et al, 2005;de Knikker et al, 2008;Maffulli et al, 2008;Lohrer & Nauck, 2009;Dogramaci et al, 2011).…”

The VISA-A questionnaire has proven to be a valid and reliable tool for assessing severity of Achilles tendinopathy (AT). The aim was to translate and cross-culturally adapt the VISA-A questionnaire for a Danish-speaking AT population, and subsequently perform validity and reliability tests. Translation and following cross-cultural adaptation was performed as translation, synthesis, reverse translation, expert review, and pretesting. The final Danish version (VISA-A-DK) was tested for reliability on healthy controls (n = 75) and patients (n = 36). Tests for internal consistency, validity, and structure were performed on 71 patients. VISA-A-DK showed good reliability for patients (r = 0.80 ICC = 0.79) and healthy individuals (r = 0.98 ICC = 0.97). Internal consistency was 0.73 (Cronbach's alpha). The mean VISA-A-DK score in AT patients was 51 [47-55]. This was significantly lower than healthy controls with a score of 93 (90-95). Criterion validity was considered good when comparing the scores of the Danish version with the original version in both healthy individuals and patients. VISA-A-DK is a valid and reliable instrument and has shown compatible to the original version in assessment of AT patients. VISA-A-DK is a useful tool in the assessment of AT, both in research and in a clinical setting.

“…20 Finally, to determine parallel-forms reliability we excluded 2 studies that had an inadequate design (failing to determine this type of reliability). 10,15 Nevertheless, for the meta-analyisis, 5,13,20,23 we could only analyze those studies in which the VISA-A had been compared with the Percy and Conochie, and Curwin and Stanish systems, 2,18 as these were the only tests used in more than one group and with the same type of coefficient (Pearson or Spearman). The parallel-forms coefficients could not be calculated in all the studies, as some of them used different correlation coefficients (Pearson and Spearman), 11,27 and others were the only ones to use a specific comparative test.…”

A Reliability Generalization Meta-Analysis of the Victorian Institute of Sport Assessment Scale for Achilles Tendinopathy (VISA-A)

Background: A reliability generalization study of a questionnaire is necessary to provide higher-level evidence for its reliability. This has not been performed for the Victorian Institute of Sport Assessment–Achilles tendinopathy (VISA-A) questionnaire. The VISA-A has been a commonly used questionnaire to evaluate the symptoms of Achilles tendon disorders and their impact on physical activity, one of the most common disorders among athletes and sports persons (9%-40%). Furthermore, this questionnaire has been translated to several languages and due to its simplicity is one of the most widely used questionnaires for patients with this type of disorder. Therefore, we performed a reliability generalization study of the VISA-A using MEDLINE (through PubMed) and Scopus as data sources. Methods: We selected studies that analyzed the reliability of the VISA-A by evaluating Cronbach’s alpha, the intraclass correlation coefficient (ICC), and the Spearman correlation coefficients to compare VISA-A with similar scales. The data were analyzed using fixed- and random-effects models. We assessed sensitivity through the leave-one-out method. Quality analysis was performed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Results: Of a total of 263 studies (eliminating duplicates), 7 fulfilled inclusion criteria. The mean reliability was (1) Cronbach’s alpha, 0.75 (95% CI, 0.70-0.79); (2) ICC, 0.91 (95% CI, 0.82-0.96); (3) correlation coefficient with the Curwin and Stanish grading system, –0.82 (95% CI, −0.93 to −0.56); and (4) correlation coefficient with the Percy and Conochie classification, 0.91 (95% CI, 0.87-0.93). We were unable to perform the funnel plot analysis and estimate meta-regression models. The Spearman correlation coefficients for both comparative scales showed influential studies (sensitivity analysis). Conclusion: Internal consistency and reproducibility were found to be good, but the parallel-forms reliability could not be supported. Therefore, more scientific evidence is needed to generalize the reliability of the VISA-A. Level of Evidence: Level I, meta-analysis of literature.
