In this research, it is aimed to examine the Facebook addiction level of high school students according to the demographical variables together with their personality characteristics. 133 female and 114 male high school students ,247 in total, were included in this study. “10-Item Personality Scale” was used to define the personal characteristics of high school students and “Facebook Addiction Scale” was implemented in order to determine their Facebook addiction level. Mann Whitney U test, Kruskal Wallis H test and Spearman Correlation analysis were used on SPSS 22.0 for the statistical analysis of the data. At the end of the study, it is found out that extroversion, emotional imbalance, openness for experience, responsibility and amiability characteristics of the participants are at the mid-level whereas their Facebook addictions are at the low level. When taken into consideration under the light of demographical variables; it is determined that personal characteristics of the high school students demonstrate a meaningful statistical differentiation according to the gender and number of devices they use (p<0.05), but personal characteristics display no meaningful statistical differentiation in terms of age and sports activities variables (p>0.05). When the findings related with Facebook addiction are evaluated, it is observed that participants’ Facebook addiction levels show meaningful statistical differentiation in terms of gender vraiable (p<0.05), whilst not displaying any meaningful statistical differentiation according to the variables of age, sports activities and number of devices used (p>0.05). Additionally, it was observed that there was no statistical meaningful relation betweem the personal characteristics of high school students and Facebook addictions (p>0.05). Consequently, demographic variables have a partial impact on the personal characteristics and Facebook addiction of high school students, but on the other hand personal characteristics are not crucially deterministic for Facebook addiction.
