Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After being informed about the study, all patients giving written informed consent will be assessed to determine eligibility for study entry.

The clinical trial will include a control group (waiting list).

Patients who meet eligibility requirements will be assigned to a waiting list, in vivo exposure and Virtual Reality.

Psychological intervention consisted in a 5-session individual face-to-face delivered ACT-based treatment.

The participants will be assessed through self-report instruments and observational measurements before and after treatment and at 3 months follow-up.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ACT+In vivo exposure

5 individual weekly sessions which included ACT methods + in vivo exposure

Group Type EXPERIMENTAL

ACT

Intervention Type BEHAVIORAL

Acceptance and Commitment Therapy methods were focused on promoting Values clarification, Acceptance, Cognitive defusion, Committed action and Flexible attention to the present moment, and included 'The dreamed professional exercise' -variation on '"imagine your funeral" exercise'-, Ship's captain metaphor, Imaginal exposure, Physicalizing exercise, and Watching thoughts as graffiti.

In vivo exposure:

Intervention Type BEHAVIORAL

The audience was made up of university students. Every session included a 12 minute oral presentation. Participants were asked to improvise a talk about a new topic (e.g. violence against women, education system in Spain…). Participants had 3 minutes to prepare their speech. Difficulty increased based on each participant's pre assessment (topics and distractors as ringtones, audience whispering...)

ACT+Virtual reality

5 individual weekly sessions which included ACT methods + virtual reality

Group Type EXPERIMENTAL

ACT

Intervention Type BEHAVIORAL

Acceptance and Commitment Therapy methods were focused on promoting Values clarification, Acceptance, Cognitive defusion, Committed action and Flexible attention to the present moment, and included 'The dreamed professional exercise' -variation on '"imagine your funeral" exercise'-, Ship's captain metaphor, Imaginal exposure, Physicalizing exercise, and Watching thoughts as graffiti.

Virtual Reality

Intervention Type BEHAVIORAL

Virtual reality was delivered through Psious platform distributed in Spain by TEA and through a Virtual Reality equipment that included a Samsung S7 mobile and Samsung Gear VR glasses.

Every session included a 12 minute oral presentation. Participants were asked to improvise a talk about a new topic (e.g. violence against women, education system in Spain…). Participants had 3 minutes to prepare their speech. Difficulty increased based on each participant's pre assessment (topics and distractors as ringtones, audience whispering...)

Waiting list

Participants assigned to Waiting List arm waited for 5 weeks before receiving treatment (i.e., after completing the measures they continued in the study and then were randomly assigned to ACT+in vivo exposure or ACT+virtual reality arms).

Group Type NO_INTERVENTION

No interventions assigned to this group
