Abstract

Objectives

Evaluate structural validity, hypothesis testing and measurement invariance of the Victorian Institute of Sport Assessment–Achilles (VISA-A) using Rasch analysis to determine if it can be recommended to measure Achilles tendinopathy severity.

Methods

We performed an evaluation of the VISA-A measurement properties using Rasch Measurement Theory by pooling individual participant data from previously conducted studies (n = 217). Structural validity was assessed via threshold/category mean order; adequate item fit; unidimensionality; local dependence; internal consistency. Hypothesis testing was assessed via divergent validity. Measurement invariance assessed via differential item functioning.

Results

The VISA-A has inadequate construct validity. This is evident from issues with item 8 and insufficient threshold order, item fit, borderline internal consistency and measurement invariance, with item response being influenced by both age and BMI.

Conclusion

The VISA-A has inadequate structural validity, borderline internal consistency and poor measurement invariance. Thus, the VISA-A does not meet with COSMIN criteria for construct validity due to issues with structural validity and measurement invariance. Thus, the VISA-A cannot be recommended for use, and should not be used in clinical practice or research. However, if the VISA-A has been used, analysis using only items 1–6, with responses collapsed into a 4-point scale provides the best structural validity.

维多利亚运动评估研究所-阿基里斯从根本上是有缺陷的，不适合临床实践或研究：使用COSMIN建议的皮疹测量理论分析

目的利用Rasch分析评估维多利亚运动评估-跟腱（VISA-A）的结构效度、假设检验和测量不变性，以确定是否可以推荐用于测量跟腱病变严重程度。方法利用Rasch测量理论对VISA-A的测量特性进行评估，并汇集了之前进行的研究中的个体参与者数据（n = 217）。通过阈值/类别平均顺序评估结构效度；适当的项目适合；unidimensionality;当地的依赖;内部一致性。假设检验通过发散效度进行评估。通过差异项目功能评估测量不变性。结果VISA-A量表构效度不足。从项目8和阈值顺序不足、项目拟合、边界内部一致性和测量不变性的问题中可以明显看出这一点，项目反应受到年龄和BMI的影响。结论VISA-A量表结构效度不足，内部一致性不稳定，测量不变性差。因此，由于结构效度和测量不稳定性的问题，VISA-A不符合COSMIN的结构效度标准。因此，VISA-A不推荐使用，不应用于临床实践或研究。然而，如果使用了VISA-A，则仅使用项目1-6进行分析，并将反应分解为4分制，可提供最佳的结构效度。

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
