Decisions to undergo invasive prenatal diagnostic procedures can be anxiety provoking. Individuals receive information about these procedures in one of three modalities: written text, audio (verbal description), or video. We examined whether modality influences emotional responses and testing decisions, and whether trait anxiety, a disposition linked with heightened sensitivity to threatening information, moderates these effects. New Zealand adults (N = 176) completed a trait anxiety measure before random allocation to view a text, audio, or video message about amniocentesis and chorionic villus sampling. Participants completed measures of child related worry, anticipated emotional distress, anticipated coping efficacy, perceived likelihood of miscarriage, and testing interest. High-anxious individuals reported greater distress and lower coping efficacy in response to the video message compared to the audio message. They also reported greater miscarriage likelihood in response to the video message compared to the text message. These findings suggest that use of video, assumed to be most informative for educating patients, could induce greater distress about prenatal testing in individuals prone to anxiety.
