Cross-cultural adaptation of the VISA-A questionnaire, an index of clinical severity for patients with Achilles tendinopathy, with reliability, validity and structure evaluations.

ABSTRACT:

Background

Achilles tendinopathy is considered to be one of the most common overuse injuries in elite and recreational athletes and the recommended treatment varies. One factor that has been stressed in the literature is the lack of standardized outcome measures that can be used in all countries. One such standardized outcome measure is the Victorian Institute of Sports Assessment - Achilles (VISA-A) questionnaire, which is designed to evaluate the clinical severity for patients with Achilles tendinopathy. The purpose of this study was to cross-culturally adapt the VISA-A questionnaire to Swedish, and to perform reliability, validity and structure evaluations.

Methods

Cross-cultural adaptation was performed in several steps including translations, synthesis of translations, back translations, expert committee review and pre-testing. The final Swedish version, the VISA-A Swedish version (VISA-A-S) was tested for reliability on healthy individuals (n = 15), and patients (n = 22). Tests for internal consistency, validity and structure were performed on 51 patients.

Results

The VISA-A-S had good reliability for patients (r = 0.89, ICC = 0.89) and healthy individuals (r = 0.89-0.99, ICC = 0.88-0.99). The internal consistency was 0.77 (Cronbach's alpha). The mean [95% confidence interval] VISA-A-S score in the 51 patients (50 [44-56]) was significantly lower than in the healthy individuals (96 [94-99]). The VISA-A-S score correlated significantly (Spearman's r = -0.68) with another tendon grading system. Criterion validity was considered good when comparing the scores of the Swedish version with the English version in both healthy individuals and patients. The factor analysis gave the factors pain/symptoms and physical activity

Conclusion

The VISA-A-S questionnaire is a reliable and valid instrument and comparable to the original version. It measures two factors: pain/symptoms and physical activity, and can be used in both research and the clinical setting.

Project description:BackgroundAchilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy. To internationally compare research results, to perform multinational studies or to exclude bias originating from subpopulations speaking different languages within one country an equivalent instrument is demanded in different languages. The aim of this study was therefore to cross-cultural adapt and validate the VISA-A questionnaire for German-speaking Achilles tendinopathy patients.MethodsAccording to the "guidelines for the process of cross-cultural adaptation of self-report measures" the VISA-A score was cross-culturally adapted into German (VISA-A-G) using six steps: Translation, synthesis, back translation, expert committee review, pretesting (n = 77), and appraisal of the adaptation process by an advisory committee determining the adequacy of the cross-cultural adaptation. The resulting VISA-A-G was then subjected to an analysis of reliability, validity, and internal consistency in 30 Achilles tendinopathy patients and 79 asymptomatic people. Concurrent validity was tested against a generic tendon grading system (Percy and Conochie) and against a classification system for the effect of pain on athletic performance (Curwin and Stanish).ResultsThe "advisory committee" determined the VISA-A-G questionnaire as been translated "acceptable". The VISA-A-G questionnaire showed moderate to excellent test-retest reliability (ICC = 0.60 to 0.97). Concurrent validity showed good coherence when correlated with the grading system of Curwin and Stanish (rho = -0.95) and for the Percy and Conochie grade of severity (rho 0.95). Internal consistency (Cronbach's alpha) for the total VISA-A-G scores of the patients was calculated to be 0.737.ConclusionThe VISA-A questionnaire was successfully cross-cultural adapted and validated for use in German speaking populations. The psychometric properties of the VISA-A-G questionnaire are similar to those of the original English version. It therefore can be recommended as a sufficiently robust tool for future measuring clinical severity of Achilles tendinopathy in German speaking patients.

Project description:BackgroundIn sporting activities, patellar tendon is commonly subjected to overuse and it influences the athletes' career especially in elite basketball and volleyball players. A condition specific and self-administrated questionnaire is required for clinical and research purpose to rate disability. The Victorian Institute of Sports Assessment for patellar tendinopathy (VISA-P) questionnaire is widely accepted and a valid tool to assess pain and athletes, suffering from PT, ability to participate in sports. So, the objective of this study is to develop and validate Kannada version of VISA-P questionnaire among Kannada speaking population athletes.ObjectiveTo translate VISA-P questionnaire into Kannada and to study reliability and validity of Kannada version.MethodologyTranslation and cross-culture adaptation were performed according to the guidelines followed internationally. Those are: translation, synthesis, back-translation, revision by expert committee, pretesting and appraisal by advisory committee. The psychometric properties were tested by administering the questionnaire to 70 subjects (35 symptomatic and 35 asymptomatic). For test-retest reliability, athletes with patellar tendinopathy were tested twice within a week and test-retest reliability was assessed by Intra-class correlation coefficient (ICC). The validity was tested by comparing the VISA-P-Kannada questionnaire (VISA-P-K) against Blazina classification of patellar tendinopathy (BCPT) using Spearman correlation coefficient.ResultThe test-retest reliability was excellent (ICC 0.97). Internal consistency was found to be good (Cronbach's alpha = 0.98). The VISA-PK showed significant correlation by comparing against Blazina and Spearman's score (r = 0.72, p < 0.01).ConclusionThe VISA-P-K translation and adaptation processes were successful. The adapted instrument demonstrated good psychometric properties. The VISA-P-K has proven to be reliable and valid tool and can be used in the Kannada speaking patients with patellar tendinopathy.
