Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Individuals between the ages of 18-65 with elevated fear of spiders are randomly assigned to one of four treatment conditions (1) biofeedback relaxation training, (2) standard exposure therapy, (3) exposure therapy with threat-relevant opposite actions, and (4) exposure therapy with threat-irrelevant opposite actions. All participants undergo an online prescreen and a face-to-face screening assessment to determine eligibility and baseline (pre-treatment) symptom severity. Participants additionally complete assessments directly after treatment (post-treatment), and approximately two weeks after treatment (follow-up). The pre-treatment assessment occurs on the same day as treatment, the post-treatment assessment occurs during the treatment visit as soon as the treatment procedure is complete, and the follow-up assessment occurs within a window of 14-21 days after the completion of treatment. Participants complete two behavioral approach tests (in the treatment context and in the generalization context) at pre-treatment, post-treatment, and follow-up. Participants complete a battery of self-report questionnaires at pre-treatment and follow-up.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Biofeedback
Biofeedback Relaxation Training
Biofeedback Relaxation Training
Participants will receive one-session biofeedback relaxation training (24 minutes) for anxiety reduction. Prior to biofeedback, participants will receive education about spiders and the development and maintenance of spider phobia.
Standard Exposure
Exposure Therapy
Exposure Therapy
Participants will receive one-session exposure therapy (24 minutes) for fear of spiders. Prior to exposure therapy, participants will receive education about spiders and the development and the development and maintenance of spider phobia.
Exposure with Threat-Relevant OAs.
Exposure with Threat-Relevant Opposite Actions
Exposure with Threat-Relevant Opposite Actions
Participants will receive one-session exposure therapy (24 minutes) for fear of spiders. During exposure, participants will engage in actions opposite to the tendencies associated with threat avoidance. Prior to exposure therapy, participants will receive education about spiders and the development and maintenance of spider phobia.
Exposure with Threat-Irrelevant OAs
Exposure with Threat-Irrelevant Opposite Actions
Exposure with Threat-Irrelevant Opposite Actions
Participants will receive one-session exposure therapy (24 minutes) for fear of spiders. During exposure therapy, participants will engage in actions opposite of the action tendencies associated with the fear, but unrelated to the specific threats associated with spider phobia. Prior to exposure therapy, participants will receive education about spiders and the development and maintenance of spider phobia.
