This study is aimed at investigating the correlation and comparison of perceived stress, intolerance of uncertainty and resilience among students as well as working individuals. The two main objectives of the research are to see if these three variables correlate with each other significantly; as well as to see the if there is a difference in the perception of intolerance of uncertainty, perceived stress and resilience between students and working individuals. The total sample consisted of 373 individuals falling between 18-40 years of age. Methodology consisted of snowball and purposive sampling. Descriptive, correlational and comparative research designs were used. Standardized tools of Perceived Stress Scale, Resilience Scale-14 and Intolerance of Uncertainty Scale were used for data collection in order to assess perceived stress, intolerance of uncertainty and resilience. The parametric measure of Pearson product moment correlation, independent sample t-test as well as regression were used for data analysis. The results revealed a significant positive correlation between intolerance of uncertainty and perceived stress and a significantly negative correlation between resilience and intolerance of uncertainty and resilience and perceived stress ( significant at 0.01 level). There is also a significant difference between perceived stress and resilience of the students and working individuals ( significant at 0.05 level).
