A Mixed Methods Approach to Measuring Depth of Group Information Processing in the Context of Deliberative Public Involvement

This article presents a mixed methods procedure for evaluating information processing and the role of social influences in deliberative public involvement groups. Specifically, it describes an interpretive, qualitative coding scheme for analyzing group discussions to quantitatively assess how group differences in information processing and social influences affect decision judgments. To substantiate the need for this new approach, the contributions of social psychology for better understanding persuasive influences in groups and individual information processing are described in relation to participatory public involvement contexts. The approach is then described using examples from a deliberative public involvement process. The article concludes with a discussion of the challenges associated with the proposed technique and suggestions for research to advance the technique and assess its contribution to mixed methods research.
