摘要

Background and Purpose: Patellar tendinopathy is one of the most common causes of anterior knee pain, particularly for sports that require repeated jumping and landing, such as volleyball and basketball. The Victorian Institution of Sports Assessment- Patellar Tendinopathy (VISA-P) questionnaire is developed in 1998 for clinical evaluation of patellar tendinopathy. The VISA-P has been adapted to several languages and proven to be a reliable and valid assessment tool for patellar tendinopathy. However, there is still no Chinese version of the VISA-P questionnaire. Thus, the purpose of the study is to adapt the VISA-P questionnaire to Chinese and to establish the reliability and validity of the Chinese version of VISA-P questionnaire. Methods: The VISA-P questionnaire was translated and adapted in Chinese populations followed the international guideline in 6 steps: initial translation, synthesis, back translation, expert committee, pretesting, and validation, and the final version of translated VISA-P was titled VISA-PCh. The psychometric properties of VISA-P-Ch were tested twice (24-48 hours apart) in 15 asymptomatic controls, and 15 individuals with symptoms of patellar tendinopathy. The face validity was determined by an expert committee. The score between two groups were compared using the independent t-test to determine the known group validity. The correlation of the VISA-PCh score and the Blazina classification was assessed using the Spearman rank correlation coefficient (ρ) to determine the concurrent validity. The test-retest reliability was examined by intraclass correlation coeifficient (ICC) in two groups respectively. The internal consistency for each item was determined using a Cronbach alpha. Results: The face validity of the VISA-P-Ch was good with good internal consistency (Cronbach's α = 0.834). The VISA-PCh had a significant correlation with the Blazina classification (ρ = -0.899; p ＜ 0.01) which indicated a perfect concurrent validity. Known group validity was demonstrated by showing significant differences in VISA-P-Ch score between the two groups (p ＜ 0.01). We also found good test-retest reliability of the VISA-P-Ch in both the patellar tendinopathy and the control group (ICC = 0.864 and 0.772 respectively). Conclusion: The VISA-P-Ch has proven to be a reliable and valid questionnaire. Clinical Relevance: The VISA-P-Ch can be used in Chinese speaking population to assess the severity of symptoms in patellar tendinopathy.
