Results: Results showed high correlation coefficient of >0.8 for convergent validity and test retest reliability.

Conclusion: The robust correlation values for convergent validity and test retest reliability indicates that the Kannada version is validated and can be used to assess and quantify the physical activity level in Kannada speakers by research groups and clinicians.
