Proper sleep length and quality are essential for physical and mental health and have found to be related to a
variety of negative outcomes (Brown, Buboltz, &Soper, 2002). College is a time,a transition for individuals where
they begin laying a foundation for their future and acquiring sufficient sleep is of great value. College students
are recognized as one of the most sleep-deprived groups, but also, as one of the most technologically-oriented
population. Due to this combination, college students’ sleep habits and mobile phone use habits havebegun to
receiveattention. The purpose of this study was to examine the relationship between sleep quality/length and
mobile phone use among college students. Three hundred and fifty college students voluntarily participated by
completing the Sleep Quality Index (SQI), The Sleep Habits Survey,the Mobile Phone Problem Use
Scale(MPPUS), the SMS Problem Use Scale (SMS-PUDQ) and the Mini IPIP. Results indicate that various
aspects of mobile phone use such as problem mobile phone use, addictive text messaging, problematic texting,
and pathological texting are related to sleep quality, but not sleep length. Additionally, extraverted individuals
were found to engage in greater mobile phone use and problematic text messaging.
