Depression among college students is a substantial concern due to the risk of suicide, academic failure, and other psychosocial problems. Current literature suggests that the prevalence of depression among populations of college students has risen in the past two decades whereas sleep quality has decreased and technology use has increased. The purpose of this study was to investigate the ways that sleep quality, technostress, and misuse of technology might be associated with depression among college students. A total of 236 college undergraduates from a large, urban university were surveyed. Independent samples t tests revealed no mean group differences between men and women for depression, sleep quality, technostress, and misuse of technology. A multiple hierarchical regression indicated that younger age and poor sleep quality were linked to higher amounts of depression among college students. Additional regression analyses revealed that technostress predicted an additional 1.1% of the variance in depression after controlling for sleep quality, and misuse of technology predicated an additional 4.9% of the variance in depression after controlling for sleep quality. A series of regression analyses to test for mediation were conducted to determine if technostress or technology misuse mediated the relationship between sleep quality and depression. Results did not support the hypotheses that partial mediation would occur. Implications regarding treatment and prevention of depression among college students were discussed.
