Comparison of Exposure Trainings for Spider Phobia German Title Vergleich Von Expositionstrainings fr Spinnenangst

What this Trial Is About

This research investigates exposure therapies for spider phobia, focusing on comparing in vivo exposure therapy IVET with videochat-based vicarious exposure therapy VicET. The study aims to evaluate fear and disgust reactions, as well as the generalization of fear and disgust, in people with spider fear. It addresses barriers to traditional exposure therapy and explores if vicarious exposure via videochat can offer a viable, less stressful alternative. Participants are randomly assigned to one of three groups IVET, VicET, or a waiting list control WLC. Each group first undergoes a pre-assessment including questionnaires, heart rate measurement, and behavioral approach tests BATs with treated and non-treated spiders. The IVET group receives a single in-person exposure session, while the VicET group watches the exposure via videochat. The WLC group does not receive exposure initially but is offered IVET after study completion. Post-assessment takes place about 24 hours later, repeating BATs and questionnaires, with a follow-up assessment approximately six weeks later using online questionnaires. During the study, participants complete various self-report measures on psychological state, spider fear, and treatment credibility. Heart rate and subjective fear and disgust are monitored throughout exposure sessions. Outcomes include changes in BAT performance, subjective fear and disgust ratings, and heart rate. The study also includes an unexpected memory test post-treatment to explore memory of therapy experiences. The total participation spans initial assessments, treatment or waiting period, post-assessment, and a six-week follow-up.
