In recent years the growing reliance on mobile phones for work, play, as well as communication has contributed to a spike in Nomophobia, the fear of being left behind without a phone. Nomophobia has been linked to various negative effects on mental and physical health, as well as academic performance. Therefore, understanding the prevalence of nomophobia among university graduate students and its associated factors is crucial in addressing the issue and developing effective interventions. The present study aimed to investigate the prevalence of nomophobia among university students in North East India and its correlation with selected socio-demographic elements, such as gender, age, residential location, type of families, educational level, type of stream, and semester of study. A descriptive survey research and convenience sampling technique was utilized to collect data from 627 graduates of the university using the standardized Nomophobia Questionnaire developed by Yildirim and Correia (2015). Descriptive and differential statistics were used for data analysis, and the results revealed that all the participating graduates experienced some level of nomophobia. Among them, the majority (66.7%) had a moderate level of nomophobia.There were no significant gender differences in the prevalence of nomophobia, with both male and female students exhibiting similar levels. However, significant differences were observed in the prevalence of nomophobia concerning factors like place of residence and education level. No significant differences were found among age, type of families, type of stream, and semester of study differences.
