A statistically significant difference (p <  0.001) was obtained between the study group and control group in all the subtest scores and on the total scores of VHI-Punjabi. Statistical significant correlation is found in two administrations of VHI-Punjabi after a gap of 2 weeks in both study group and control group (p <  0.001).
