The study aims to investigate the interrelationships between perfectionism, rumination, and the impostor phenomenon in young Indian adults. The study employs a non-experimental quantitative correlational research design. The sample consists of 162 young adults aged between 18 and 26 years, selected through convenience sampling. Results indicated a significant positive correlation between perfectionism and imposter phenomenon. Dimensions of perfectionism such as the need for approval, organization, and reluctance were identified as the best predictors of the phenomenon. Moreover, the regression analysis gave a statistically significant result (F = 8.407, p 0.001), indicating that one of the independent variables significantly predicts the phenomenon, highlighting the role of rumination in worsening distress associated with perfectionism. Interventions targeting refractory emotions could offer promise in alleviating imposter-related distress, focusing on the importance of addressing underlying cognitive and emotional processes.
