Abstract

According to the rational choice model, informed consent should consist of a systematic, step-by-step evaluation of all information pertinent to the treatment or research participation decision. Research shows that people frequently deviate from this normative model, however, employing decision-making shortcuts, or heuristics. In this paper we report findings from a qualitative study of 32 adolescents and (their) 31 parents who were recruited from two Northeastern US hospitals and asked to consider the risks of and make hypothetical decisions about research participation. The purpose of this study was to increase our understanding of how diabetic and at-risk adolescents (i.e., those who are obese and/or have a family history of diabetes) and their parents perceive risks and make decisions about research participation. Using data collected from adolescents and parents, we identify heuristic decision processes in which participant perceptions of risk magnitude, which are formed quickly and intuitively and appear to be based on affective responses to information, are far more prominent and central to the participation decision than are perceptions of probability. We discuss participants' use of decision-making heuristics in the context of recent research on affect and decision processes, and we consider the implications of these findings for researchers.
