简要总结
Patients with anxiety disorders oftentimes express fear responses to more than only one fear-inducing object. The principal aim of this study is to examine whether the beneficial effects of exposure on fear reduction in spider phobia can extend to stimuli which are conceptually similar to spiders (i.e. cockroaches), but have never been presented during the respective treatment.
详细描述
Fear extinction has evolved as the central mechanism underlying exposure-based treatments. Findings from conditioning studies indicate that fear reduction following a fear extinction procedure can generalize from the extinction stimulus to other conceptually and perceptually related stimuli. This study is aimed at translating these findings to a clinical application and will hence examine whether the basic principles of extinction generalization are applicable to exposure.
Patients with spider phobia will either receive two sessions of in-vivo exposure with spiders or no treatment. Prior to as well as after treatment, patient's fear of spiders will be assessed using the Behavioral Approach Test (BATs) and self-report questionnaires. In addition, BATs with cockroaches will be conducted to examine the effects of exposure therapy on extinction generalization.

结局指标
主要结局
Change in the Behavioral Approach Test (BAT) from pre- to posttreatment
时间窗: Pre- and Posttreatment (with approximately 4 days between pre- and posttreatment)
Behavioral Approach Tests with Spiders and Cockroaches will be conducted at pre- and posttreatment. Here, the closest proximity a participant is able to attain to the spider/cockroach will be measured.
次要结局
- Change in Heart Rate during the Behavioral Approach Tests (BATs) from pre- to posttreatment(Pre- and Posttreatment (with approximately 4 days between pre- and posttreatment))
- Change in the Spider Phobia Questionnaire (SPQ)(Pre- and Posttreatment (with approximately 4 days between pre- and posttreatment))
- Change in the Spider Beliefs Questionnaire (SBQ)(Pre- and Posttreatment (with approximately 4 days between pre- and posttreatment))
- Change in the Fear of Spiders Questionnaire (FSQ)(Pre- and Posttreatment (with approximately 4 days between pre- and posttreatment))
- Change in Subjective Fear / Disgust during the Behavioral Approach Tests (BATs) using the Subjective Units of Distress Scale (SUDS)(Pre-and Posttreatment (with approximately 4 days between pre- and posttreatment))
