NCT03601377

Brief Summary

This study evaluates attention modification in social anxiety and It is comprised by 2 experiments. At experiment 1 socially anxious participants will receive either training away from threatening faces or placebo intervention and at experiment 2 they will receive either one of these 2 groups or training towards threatening faces. At experiment 2 training will be done under state anxiety levels (video-recording of a speech). Anxiety levels (self-reports, physiological and behavioral measures) as well as attentional biases changes will be examined at pre and post - intervention levels plus 6 months follow-up only for experiment 1.

Outcome Measures

Primary Outcomes (8)

  • Social Anxiety levels

    Experiment 1 \& 2: self-reported questionnaires, with the primary one to be Social Phobia and Anxiety Inventory-23.

    Pre-treatment (day 1)

  • Social Anxiety changes

    Experiment 1 \& 2: Measured in self-reported questionnaires with the primary one to be Social Phobia and Anxiety Inventory-23.

    Experiment 1: 4 weeks after the day 1, Experiment 2: 3 weeks after the day 1 (Post-treatment)

  • Social Anxiety changes

    Only for experiment 1: Measured in self-reported questionnaires with the primary one to be Social Phobia and Anxiety Inventory-23.

    6 months after day 1 (Follow-up)

  • Attentional Biases

    For experiment 1: Assess kind of attentional biases using the dot-probe task (comparison of reaction time to threatening and a neutral stimulus). For experiment 2: Assess kind of attentional biases using the eye-tracking task (measuring eye gaze).

    Pre-treatment (day 1)

  • Attentional Biases changes

    For experiment 1: Assess kind of attentional biases using the dot-probe task (comparison of reaction time to threatening and a neutral stimulus). For experiment 2: Assess kind of attentional biases using the eye-tracking task (measuring eye gaze).

    4 weeks after the day 1 (Post-treatment)

Training away from threat

EXPERIMENTAL

Experiment 1 and 2: In the intervention group -training away from threat-, in all angry-neutral faces presentation the probe is presented only after neutral face. Probe type (\< or \>) is not factorially counterbalanced but there is equal possibility of presentation for each of the following: angry-face location, probe location, or actor. Experiment 1: received 8 times (2 times per week for 4 weeks) Experiment 2: received 4 times (2 times for 2 weeks)

Behavioral: Training away from threat

Training towards threat

EXPERIMENTAL

Only for Experiment 2: The second ABMT condition -training towards threat- is identical to the first one with the exception that in all angry-neutral face presentations the symbol is presented only after threat face. In addition, at the beginning of every session participants will be informed that a random number of participants will have to repeat their speech. They will also be informed that this instruction will be given right after the dot probe task completion. This will be done in order for the participants to maintain their state anxiety but repetition of the speech task will not actually happen at this stage. Experiment 2: received 4 times (2 times for 2 weeks)

Behavioral: Training towards threat

Placebo

PLACEBO COMPARATOR

Experiment 1 and 2: In the placebo group, angry-face location, probe location and actor are fully counterbalanced with regards to their presentation. Experiment 1: received 8 times (2 times per week for 4 weeks) Experiment 2: received 4 times (2 times for 2 weeks)

Behavioral: Placebo

Interventions

Dot-probe task: Pairs of stimuli, angry - neutral face or neutral - neutral faces of the same actor (20 different individuals;10 male, 10 female) are presented horizontally in the centre of the screen (160 trials; 120 angry-neutral and 40 neutral-neutral). Each trial begins with a fixation cross (500 ms), on which the participants are instructed to focus their gaze. After that a pair of faces follows which is presented on the screen for 500ms. After the faces presentation a small visual probe (\< or \>) appears at the same place of one of the two faces. Participants have to determine which symbol appeared by clicking right or left on the mouse as quickly as possible. The target probe remains on the screen until there is a response, which starts a new trial.
