In our technologically ever-advancing world, cell phones can either help us remain socially connected or can contribute to social isolation by substituting for face-to-face contact. This study examines the levels of social isolation in terms of the state of loneliness and trait of shyness and their correlations with academic achievement in 206 community college and university students to examine the connection between social isolation, GPA and cell phone use in college students. Two instruments used in the collection of data were the Revised Cheek and Buss Shyness Scale (RCBS) and the DeJong Gierveld Loneliness Scale. Correlational analysis was used to examine the relationships between variables. Hypothesis 1 proposed a significant negative relationship between higher levels of cell phone use and academic achievement as measured by self-reported GPA. This was partially supported by the research findings. Hypothesis 2 proposed a significant negative relationship between shyness and higher levels of cell phone use. This was also partially supported by the research findings. Hypothesis 3 proposed a significant positive relationship between loneliness and higher levels of cell phone use. This was not supported by research findings. Implications for further research include examining non-college populations for greater generalization of results and examining additional personality traits.
