Abstract:
Prospective research participants do not always retain information provided during consent procedures. This may be relatively common in online research and is considered particularly problematic when the research carries risks. Clinical psychology studies using the trauma film paradigm, which aims to elicit an emotional response, provide an example. In the two studies presented here, 112-126 participants were informed they would be taking part in an online study using a variant of this paradigm. The information was provided across five digital pages using either a standard or an interactive format. In both studies, compared to the control condition, participants in the interactive condition showed more retention of information. However, this was only found for information about which they had been previously asked via the interactive format. Therefore, the impact of adding interactivity to digital study information was limited. True informed consent for an online study may require additional measures.
