Prior knowledge, credibility and information search

The purpose of this study was to assess the relationship between prior knowledge, source credibility, and information search behavior. The specific objectives were to determine whether prior knowledge is a multidimensional construct, document how this influences individuals' information search behavior, and assess the combined influence of it and credibility of sources used on information search behavior. The results provided evidence that prior knowledge may be a multidimensional construct; that when addressed independently, it does influence individuals' search for vacation information; and that source credibility is the strongest predictor of type of information sources used. These results challenge traditional thinking about the variables that impact tourists' information search behavior, specifically within the context of a resort-based vacation.
