This study examines the impact of consumer trust and knowledge on consumer attitude, anxiety and function, depending on the source of information on risks from chemical household products. The results of the analyses are as follows. First, among the media delivering the risk information on chemical household products, consumer’ trust level was found the highest in expert groups, followed by internet cafe/blogs, presses/broadcasts and government agencies. Second, according to the path coefficients and the regression coefficients between independent and dependent variables of the consumer trust-anxiety-competency model for each of the information sources, only press/broadcast was found to have a significant impact on consumer anxiety among the four sources of risk information on chemical household products. It suggests that there is a need to reduce consumer anxiety and to strengthen consumer competency.
