The purpose of the present study was to explore the nature of the relationships among Internet addiction, psychological well-being, and sleep quality in school students of the Bundelkhand region, UP, India. It was hypothesized that there will be no significant relationships among the above-mentioned variables in adolescents. The sample (126 students) was selected by the simple random sampling, from the different public and private schools, between the age-range of 15 to 19 years. Internet addiction scale (Young, 1998), Psychological Well-being Scale (Ryff, 1989), and Sleep Quality Scale (YI, H., et al., 2006) was used. With the help of SPSS (version, 21) the data was computed, including; mean, SD, Pearson correlation coefficient, and linear regression. The results were concluded that the negative correlation was found among Internet addiction, psychological well-being, and its sub-dimensions. Moreover, a positive correlation was found among Internet addiction, poor sleep quality, and its dimensions.
