Intolerance of Uncertainty Moderates the Relation Between the Choice to Access Health Information and Post-Choice Distress Among Individuals Prone to Health Anxiety.

Access to health information has steeply grown, mainly through the availability of online health information. Associated with a number of potential benefits, accessing health information can be non-adaptive and particularly for individuals prone to health anxiety. For those individuals, accessing health information often serves as reassurance seeking to assuage health concerns. However, accessing health information can prompt distress for individuals prone to health anxiety. The present study sought to further understand when accessing health information prompts distress by examining the moderating role of intolerance of uncertainty (IU). Individuals prone to health anxiety ( = 98), as indicated by an elevated score on a self-report measure rather than through formal assessment of meeting criteria for disorders marked by elevated health anxiety (e.g., illness anxiety disorder), participated in a lab-based session where they viewed a provocation of health concerns and were given the choice to either access or avoid further health information. As predicted, participants with high, but not low, IU reported significantly greater distress when they chose to access versus avoid health information. Study results further highlight IU as potentially important for understanding when accessing health information relates to greater negative emotionality. Future directions are discussed.
