How do state and trait differences in uncertainty affect responses to a sexual health threat? In a series of studies we investigated how these differences in uncertainty relate to affective (e.g. anxiety) and behavioural (e.g. information-seeking) responses. We showed that a greater intolerance of uncertainty (IU) leads to more information-seeking about a health threat and individuals with higher IU sought the most information and worried most when they perceived the uncertainty surrounding a health threat to be higher rather than lower.
We then examined these questions using the real health threat of the human papillomavirus (HPV), a sexually transmitted infection that causes cervical cancer. We used a randomized controlled design to study the impact of an IU on anxiety after receiving an informational intervention about HPV in a clinical population of women. We found that meeting the informational needs of women with higher IU (i.e. giving them a lot of information about HPV) increased their anxiety compared to giving them less information. This heightened anxiety may arise because HPV is a health threat whereby uncertainty cannot be resolved through more information. Taken together, this research informed health providers regarding the potential positive and negative effects of uncertainty-inducing information.
