What this trial is about
After screening (including parts of the Mini-DIPS), participants will receive a pre-assessment with a baseline heartrate measurement, self-report measures and two BATs (with the treated spider and the non-treated spider). All participants receive a brief psychoeducation \& video demonstration of exposure steps. Participants are randomly assigned to the three study arms and are then set to receive a single session of either in vivo exposure (IVET), videochat based vicarious exposure (VicET) or neither (Waiting List Control, WLC). Approximately 24 hours later, the two BATs with both spiders, a slightly reduced set of self-report measures and an interview will conduct the post-assessment. The order of all BATs, the spider individuals (treated vs. non-treated spider) and assignment to study arms will be randomized using a list that will be worked through in a sequence determined using "www.random.org". At a six-week follow-up, another long-term assessment will be conducted. Here, participants will receive a brief online questionnaire related to their experiences with spiders and self-report measures that were previously administered. Participants previously assigned to the waiting list control (WLC) will be invited to participate in an in-vivo exposure session. A set of questionnaires including demographic information, VAS scales on the current psychological state and wellbeing (administered at the start and end of the first and second assessment day), the BDI-II, the STAI-T and STAI-S, FEE, SPQ, SBQ, FSQ, GSE, SEQ-SP, TC/E for treatment credibility and the "positive attitudes towards technology subscale" of the MTUA will be used. BDI-II, STAI and MTUA are only administered at pre-assessment. The SAS is used for initial screening.
