The aim of this study was to explore the relationship between subjective well-being and locus of control among businessmen and professionals. Additionally, the study aimed to investigate the association between subjective well-being and emotional intelligence. The sample of the study consisted of 302 businessmen and professionals from different districts of Bihar, India. The participants were selected using a purposive-cum-incidental sampling method. The researchers measured the participants' subjective well-being using the Satisfaction with Life Scale (SWLS) developed by Diener et al. (1985) and Ed Diener et al.'s (2009) Scale of Positive and Negative Experience (SPANE). Furthermore, the locus of control scale developed by Julian Rotter (1966) was used to measure the participants' locus of control. Finally, the participants' emotional intelligence was assessed using a scale developed by Dr. Arun Kumar Singh and Dr. Shruti Narain. The study found a strong relationship between subjective well-being and locus of control. The businessmen reported a higher level of subjective well-being than professionals. Additionally, the study found a positive correlation between emotional intelligence and subjective well-being.
