The Effect of Positive Emotion and Perceived Risk on Usage Intention to Online Decision Aids

Although perceived risk has a negative effect on usage intention toward new information technology, both perceived risk and usage intention are the results of cognitive processes, so they are inevitably influenced by emotion. Based on positive mood theory and the appraisal-tendency framework (ATF), a laboratory experiment using online decision aids with 126 participants was conducted. The results indicate that positive emotion (happy emotion in the current study) can increase usage intention and decrease perceived risk, while perceived risk decreases usage intention. Further investigation finds that perceived risk is a mediator between emotion and usage intention.
