Abstract

Abstract Digital informed consent with interactive elements was better remembered by undergraduate participants than other or none modifications of information forms (Geier et al, 2021). Consistent with this finding, Aan het Rot & Wessel (2022) found in a comparable online study that participants scored higher on a retention test who answered multiple-choice questions at the end of each information form page compared to a control condition without interactivity. First-year Psychology students (N = 133) at the University of Groningen were randomly allocated to two consent procedures (high interactivity; n = 70 vs control; n = 63), based on the same experimental design as used by Geier and colleagues (2021) but adding a deception. The information and consent form were taken from an trauma-film paradigm study. Participants expected to see emotional pictures after consenting and were not aware of being assessed on a retention test after reading the information form. The present study aimed to replicate the previous findings that adding multiple-choice questions to the information form improved how many details participants remembered about the study information and further investigated the effect of question type (i.e., whether multiple-choice question of the retention test were previously asked) as well as a potential moderating effect of the presence of a trauma history in participants. Data was collected through an online questionnaire and analyzed by a two-sample t-test, a mixed-design ANOVA and a two-way ANOVA. Results showed a significant difference in retention scores for participants in the high interactivity condition. Furthermore, the effect was positively moderated by the question type. Results did not support better retention for participants with a trauma history and did not confirm a moderating effect of trauma history.
