The correlation between interpersonal relationship satisfaction and SNS addiction tendency was analyzed after checking the degree of interpersonal relationship satisfaction and SNS addiction tendency through the collected data. The results of the study are as follows. First, the overall average of pre-service early childhood teachers satisfaction with interpersonal relations was 3.71(SD=0.41). Among the sub-factors, the average of comprehension was the highest, followed by friendliness, sensitivity, openness, communication, trust and satisfaction. Second, the overall average of pre-service early childhood teachers’ SNS addiction tendency was 2.08(SD=0.51). Among the sub-factors, the average of immersion and resistance was the highest, followed by adjustment failure and daily disability, avoidance of negativity, virtual world orientation and withdrawal. Third, the overall interpersonal relationship satisfaction and SNS addiction tendency of pre-service early childhood
teachers showed a statistically significant positive correlation. Looking at the sub-factories, only sensitivity, a sub-factor of interpersonal relationship satisfaction, turned out to be an incidental correlation to SNS addiction tendency, but all other things turned out to be static correlations.
