چکیده

OBJECTIVE The Internet has expanded the scope for creating health scares and increased the risk of nocebo responding in individuals exposed to misinformation about threats to personal health posed by aspects of modern life, such as exposure to new technologies. It was the aim of this experiment to investigate whether the delivery of positive expectations might reduce or reverse symptoms triggered by negative expectations formed from such misinformation. METHOD In the context of a study investigating symptoms during exposure to windfarm sound, 64 volunteers assessed their symptomatic experiences during two discrete sessions, throughout which they listened to wind turbine sound containing audible and sub-audible (infrasound) components. Participants were randomly assigned to watch either positive or negative information about the health effects of infrasound prior to their first infrasound exposure session. They were then shown the alternate information and exposed to infrasound during their second session. RESULTS Participants receiving negative expectations were less symptomatic during exposure if they had previously received positive expectations about infrasound. Further, participants given positive expectations after the earlier delivery of negative expectations exhibited a placebo response, reversing the nocebo response exhibited in their first exposure session. CONCLUSION Results suggest accessing positively framed health information may reverse or dilute the effect of negative expectations formed from exposure to media warnings about health risks posed by new technologies, such as wind turbines.
