Explaining the Role of Perceived Risk,Knowledge, Price,and Cost in Dry Fish Consumption Within the Theory of Planned Behavior

ABSTRACT

The general purpose of this study is to explore the influence of perceived risk, knowledge, price, and cost of dry fish consumption in Bangladesh using the general framework from the theory of planned behavior (TPB). The field experiments were performed in Bangladesh with a convenience sample of 558 respondents. Multiple regression analysis was used to investigate the relationship among perceived risk, knowledge, price, and cost and TPB constructs. The findings showed that attitude, norms, and procedural knowledge emerge as the key determinants of intention, whereas intention, attitude, norms, and perceived risk have effects on the dry fish consumption frequency. Perceived behavioral control, price, and cost had no significant effect on intention and consumption behavior. The proposed TPB and the extended model both fit the data well and proved the expectations of this study in a promising way. The study found that people are more concerned about potential long-term risk to their family and others. Therefore, management attention should focus on reducing risks which consumers may face through producing safe and hazard-free dry fish.
