Targeting negative flashforward imagery in speech anxiety with a visuospatial dual-task: Do attenuated flashforwards lead to less anxiety and avoidance?

Background and objectives: It has been proposed that negative mental imagery plays an important role in the persistence of social fears. Experiencing vivid and distressing 'flashforward' images of a potential social catastrophe appears to be of relevance in speech anxiety. To clarify the role of these images, the current experimental study tested if reducing the vividness and distressing properties of recurring negative flashforward images subsequently reduces anxiety and avoidance tendencies regarding a speech. Methods: Participants were female undergraduates high in speech anxiety (N = 134) who joined our study online. In the experimental condition, we used a visuospatial dual-task to reduce the vividness and distress of flashforward imagery. Primary outcomes were participants' self-reported anxiety and avoidance ratings in anticipation of and during an actual speech. As a secondary outcome, we used observer ratings of participants' anxiety during the speech. Results: Participants reported moderate to high frequency and interference of their vivid and distressing flashforward images in daily life. The dual-task resulted in reductions in image vividness and distress. However, we found no differences between conditions in anxiety and avoidance ratings before and during the speech. Limitations: The imagery manipulation effect was moderate to small. Moreover, we included a subclinical sample. Conclusions: Reducing negative flashforward imagery vividness and distress with a visuospatial dual-task did not directly lead to less anxiety and avoidance tendencies related to a later speech. Thus, findings provided no support for the hypothesis that experiencing highly vivid and distressing flashforward images causally contributes to social fears.
