This research examines the psychological processes and factors that shape illness-detection versus illness-prevention health actions. Four experiments using contexts of mental health, skin cancer, and breast cancer show that illness detection evokes fear, which undermines engagement in detection behaviors. Considering detection at low (vs. high) levels of thought reduced fear and increased health persuasion. Illness prevention is driven by self-efficacy perceptions and considering prevention at high (vs. low) levels of thought increases persuasion. In further evidence of process, trait fear moderated the detection effects, and dispositional self-efficacy moderated the prevention effects. As an intervention, framing a detection action as serving illness-prevention goals increased people’s likelihood of engaging with an online breast cancer detection tool. These findings illuminate the psychology of detection as being distinct from the psychology of prevention, identify the role of fear in the consideration of health behaviors, and show contexts in which construal levels have divergent effects on health persuasion.

AbstractA growing stream of research has examined emotions and decision‐making based on the appraisal tendencies associated with emotions. This paper outlines two general approaches that can lead to further our understanding of the variety of ways emotions affect decision‐making and information processing. Specifically, future research can examine the nature of emotional appraisals or investigate the nature of decision contexts and underlying psychological processes influenced by emotions. To understand the nature of emotional appraisals, scholars could examine the interaction of two appraisal dimensions or identify novel appraisal tendencies. To understand the decision‐making contexts and psychological processes influenced by emotions, scholars could examine how emotions interact with contextual influences to shape judgments through a variety of processes such as providing information, priming goals, or activating mindsets. These approaches to the study of emotions and decision‐making will contribute to more nuanced theory development around emotions, nurture new empirical work, and encourage interest in exploring a broader set of emotions.
