Previous crisis management research has mainly focused on business organizations' responsibility for crises, and yet research on CEOs in crisis still lacks. This research examined the influences of crisis responsibility and response strategies on attitudes toward a CEO, attitudes toward a corporate, and purchase intentions in the case of CEOs in crisis. In addition, this study explored how a CEO's SNS interactivity during normal times moderates the influences of crisis responsibility and response strategies. A 2(responsibility: high vs. low)X2(strategy: defensive vs. apology)X2(interactivity: high vs. low) experimental design was conducted with 200 Chinese students in Seoul. According to the analysis results from effects of response strategies by CEO's crisis responsibility levels, regardless of the crisis responsibility levels, the apology strategy was more effective than the defensive strategy in terms of CEO attitudes, corporate attitudes, and purchasing intentions. The analysis results about the moderating role of SNS interactivity during normal times show that under the CEO's high responsibility condition, keeping high SNS interactivity during normal times and using the apology after crisis brought out most favorable responses. Under the CEO's low responsibility condition, regardless of the SNS interactivity levels, the apology strategy brought out more favorable responses than the defensive strategy.
