About
This study investigates whether stress can augment exposure therapy outcome in patients with specific phobia (spider phobia).
Full description
Stress has been shown to modulate fear extinction. The present study is aimed at investigating whether stress (administered prior to exposure with the socially evaluated cold pressor test) augments exposure therapy outcome in patients with specific phobia (spider phobia). Furthermore, the effects of stress on the generalization of exposure-induced symptom reduction towards untreated fear stimuli (i.e. cockroaches) will be explored.
Participants are randomly assigned to the cold or warm water condition of the socially evaluated cold pressor test (SECPT; Schwabe et al., 2008). Thereafter, participants of both conditions receive 45 minutes of in-vivo exposure to spiders. The effects of stress on exposure-based anxiety reductions toward spiders (treated fear stimulus) and cockroaches (untreated fear stimulus to assess generalization of treatment outcome) are assessed on the behavioral, subjective and physiological level at pretreatment, posttreatment (24 hours after exposure) and follow-up (4 weeks after exposure).
