Situational Crisis communication theory (SCCT), one of the major crisis communication theories, suggests that crisis managers have to choose the most effective crisis response strategy in accordance to the crisis type. However, there's a controversy over whether this theory is practically applicable in Korea. Therefore, this study analyzed statements of apology to see if companies in Korea are actually taking different response strategy according to the types of crisis.According to the result of analysis on 244 apology statements published in the newspapers from 2012 to spring of 2015, adaptive response strategy was mostly taken no matter what the crisis type was. In conclusion, there's a discrepancy in crisis response strategy between the theory suggested in SCCT and the current practices in Korea. This conclusion can contribute to devising an appropriate application of SCCT in Korea and to develop a more Korea relevant theory.
