Introduction: The Shoulder pain and disability index (SPADI) is a commonly used patient rated outcome measure to assess the impact of shoulder disorders on pain and disability. The Shoulder impingement syndrome (SIS) is patho-mechanical disorder frequently affecting overhead athletes.
Aim: The aim of this study was to determine the psychometric properties of the Hindi version SPADI using Confirmatory factor analysis (CFA) in overhead athletes with SIS.
Materials and Methods: In this cross-sectional study, the athletes were first familiarised with the Hindi SPADI scale and then asked to complete the Hindi version SPADI scale. Construct validity using CFA method and Composite reliability (CR) with help of derived factor loadings and average error variance was calculated.
Results: A total of 80 overhead male athletes with SIS were recruited after standardised clinical diagnosis. The athletes had an age range of 17-25 years The results showed that five factor thirteen item Hindi version SPADI demonstrated acceptable levels of fit indices (Comparative fit index=0.93, Goodness of fit index=0.87 and Absolute goodness of fit index=0.80, Root mean square of approximation=0.065 and chi-squared degree of freedom=1.34). The CR value of each factor ranged from 0.60 to 0.74 indicating satisfactory reliability.
Conclusion: The five factor thirteen items Hindi SPADI has acceptable psychometric properties and composite reliability and is suitable for use in overhead athletes with SIS. This will help in addressing disability causing health issue.
