Responsiveness of Hindi Version of Oral Health Impact Profile for Periodontitis (OHIP-P-HIN)

The distribution- and anchor-based methods will be used to estimate the Minimal Important Difference (MID) of the OHIP-P-HIN. Two established distribution-based approaches, the standardized effect size (ES) and standardized response mean (SRM) will be calculated. The ES is calculated by dividing the mean change scores in the OHIP-P-HIN from baseline by the standard deviation of the baseline scores. And the SRM are computed as ratios of the mean change score divided by its standard deviation. The anchor-based approach will be applied by using the global transition scale as the anchor.
