Cross-cultural adaptation of the Victorian institute of sports assessment - Hamstrings (VISA-H) questionnaire for Spanish speaking athletes with proximal hamstring tendinopathy

Abstract

Objective: To cross-culturally adapt and validate the Victorian Institute of Sports Assessment e Ham strings (VISA-H) scale into Spanish. Design: Clinical measurement study (psychometric analysis). Setting: Sports clubs and physiotherapy clinics. Participants: The Spanish version of the VISA-H (VISA-H-Sp) scale was administered to 101 subjects: 50 healthy runners and 51 patients with a clinical diagnosis of PHT. Main measures: The Victorian Institute of Sports Assessment e Hamstrings. Results: Cronbach's alpha for the VISA-H-Sp was >0.8. The ICC 2,1 was 0.993 (95%CI 0.991e0.995). In the exploratory factor analysis, a one-factor solution explained 72.1% of the total variance. Athletes with PHT scored significantly lower in the VISA-H-Sp than healthy subjects (P < 0.001). The VISA-H-Sp score re sults in the PHT group showed significant correlations with SF-36 physical components (Spearman r’>0.6; P < 0.001), and low or non-significant association with psychological dimensions. The standard error of measurement was 1.45 whereas the minimal detectable change was 4.02 points. The respon siveness indicators included an effect size of 2.75, and a standardised response mean of 3.1 at discharge. Conclusion: The VISA-H-Sp shows adequate psychometric properties for assessing the severity of symptoms in Spanish-speaking athletes who suffer from PH.
