The purpose of this study is to test the relationships between teacher candidates' technology addiction and their social connectedness. Students studying at a faculty of education in a state university selected by the convenience sampling method constituted the sample of the study. Correlation analysis and association rules were used to analyze the data. The results of the study are as follows: (1) Social connectedness is inversely related to social media addiction and digital game addiction; (2) If Internet addiction and smartphone addiction are low while social connectedness is high, social media addiction is low; and (3) If social media addiction and smartphone addiction are low and social connectedness is high, digital game addiction is also low.
