This paper introduces a theoretical framework that describes the importance of public's information sufficiency, risk perception, and self-efficacy as predictors of intended risk information seeking behaviour. Based on theoretical assumptions, measurement instruments for relevant concepts were developed and validated using data from a mail questionnaire. Relationships among selected determinants of risk information seeking behaviour were analysed. Results indicate that information needs, risk perception, and current knowledge are direct predictors of intentions to seek information. Trust, engagement, social influence, and self-efficacy affect risk perception and the need for information is influenced by engagement and social influence.
