ABSTRACT
People often overestimate the duration and intensity of emotional impact for future health events, leading to sub-optimal decision-making. Previous attempts to mitigate these affective forecasting errors have had only limited success. Across two experiments with different emotional appeals (fear and disgust), health contexts (genetic testing and colonoscopy), and samples (women and African American men), this research explored the potential of emotional flow in testimonials to attenuate affective forecasting errors and increase positive health outcomes. Both studies demonstrated that a narrative intervention that mirrored shifts in emotional intensity throughout health-screening procedure testimonials increased affective forecasting accuracy and behavioral intent. These findings highlight the importance of incorporating emotional shifts in narratives to facilitate individuals’ ability to better predict future emotional reactions.

2 The attention check included four true/false questions, such as “the main character in the story had a family history of cancer” and “the main character in the story did not share her test results with family members.” Participants were excluded if they responded to two or more questions incorrectly.
3 A priori power analysis (G* Power 3; Faul et al., Citation2007) suggested that in order to detect a small-medium effect size of f = .20 at α = .05 and 1 –β = .80, the minimum required total sample size is 350.
