The dental graduation program is stressful and challenging as it is essential to master various skills. The emotional intelligence (EI) is reported to help in perceiving, moderating emotions and also play a significant role in academic excellence.The aim of this study was to assess the sociodemographic factors influencing EI and to determine the association of EI in academic performance of clinical and preclinical courses.This cross-sectional study included the 113 dental clinical internship students from five different dental schools at Pakistan. The self-administered questionnaire data included sociodemographic factors, academic performance in preclinical, clinical courses, and San Diego City College MESA Program-based EI responses. The results were analyzed with multiple linear regression and ordinal regression to identify the independent predictor for EI and academic performance.The female participants had marginally higher mean EI score (109.67) in comparison to male counterparts (108.10). The independent predictors among sociodemographic factors for EI were having siblings (P = 0.016), loss of parents (P = 0.002), parents' education (P = 0.022), and relation with parents (P = 0.03). The students enjoy studying dentistry were also associated with higher EI scores (P = 0.002). The mean EI score was an independent predictor of academic performance predominantly in clinical courses [β = -0.041 (95% confidence interval - 0.063 to - 0.020); P = 0.000].The finding of the study indicates the influence of family and social factors in the development of EI. The dental students' EI is vital for higher academic performance in clinical courses.
