Background: Metabolic equivalents (METs) are used during exercise testing as an estimate of functional capacity. There are specifically designed questionnaires to find out MET and exercise capacity. The Duke Activity Status Index (DASI) is a self-administered questionnaire designed to assess physical function and predict exercise capacity. The Modified Chinese version Veterans Specific Activity Questionnaire (VSAQ) is a 13-item self-administered questionnaire that estimates functional capacity expressed in METs. Materials and methods: Two hundred and thirty participants were included in the study according to inclusion criteria and were made to answer DASI and Modified Chinese version VSAQ, and METs were calculated. Participants performed treadmill test, i.e., Bruce Protocol. All the vital parameters were assessed before and after the completion of the treadmill test and METs achieved at that stage were noted. Results: The limits of agreement between DASI, VSAQ, and Bruce Protocol were assessed using Bland–Altman method. Duke Activity Status Index and Bruce Protocol showed p – 0.001, CI – 95%, and Modified Chinese version of VSAQ and Bruce Protocol showed p – 0.001, CI – 95%. The mean of MET calculated by the Modified Chinese version of VSAQ was statistically close to the mean of MET calculated by Bruce Protocol MET. Conclusion: There is no agreement between DASI and the Modified Chinese version of VSAQ with Bruce Protocol in healthy individuals. The Modified Chinese version of VSAQ has closer MET values to Bruce Protocol. Hence, the Modified Chinese version of VSAQ may be considered for the assessment of functional capacity in the Indian population.
