Study: NCT04553120

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Alternating single stimulus and multiple stimuli
Description: P-ARET for cockroach phobia alternating between two interventions: exposure to a single stimulus (always using the same projected cockroach) and exposure to multiple stimuli (different cockroaches in terms of number, shape, colour and movement). It will be counterbalanced to start the same number of participants in each of the two modalities. The two conditions will be randomly applied for each participant, with the restriction of that each condition will be applied 3 times.~There will be 6 weekly sessions of approximately 1 hour. The purpose of this exposure treatment is to confront patients to the phobic stimuli in a controlled manner, which favors the habituation process and allows them to accept that the negative consequences they fear do not actually occur. All exposure sessions should be recorded (patients will sign informed consent for recording prior to treatment initiation).
