Brief Summary

The study aims to develop and implement a self-applied online psychological intervention for the correction of Emotional Reasoning bias for people with public speaking anxiety. By comparing the effects of this training for ER biases vs. a non-specific mindfulness intervention, the newly developed intervention is expected to promote a greater reduction in emotional reasoning bias and the severity of symptomatology associated with public speaking anxiety.

Detailed Description

Among anxiety disorders, one of the most common is Social Anxiety Disorder. Particularly, the specific subtype performance only, i.e., public speaking anxiety, has a prevalence rate of 33% in community samples, being one of the disorders that cause major occupational, educational and social interferences, which represent a high impact on daily functioning. Several cognitive factors may prevent patients from correcting negative thinking; one is the Emotional Reasoning bias. Therefore, in the present study, the aim is to implement training for correcting Emotional Reasoning biases as a transdiagnostic process in people with public speaking anxiety. Regarding implementation and dissemination, it is proposed that this treatment be Internet-based and delivered through information and communication technologies (ICT).

To evaluate the effects of this intervention, a randomized controlled trial will be conducted, comparing two arms, an experimental group to which the bias correction training will be applied and a control group, to which a non-specific intervention will be used. A total of 158 participants based on calculations with the G\*Power program will be randomly allocated to an intervention group (N=79) and a control group (N=79). Bias correction training consists of 12 daily self-applied sessions in which components such as psychoeducation in emotions and the detection of ER biases and their impact on behavior are targeted. The primary outcome measure will be Emotional reasoning bias severity and symptomatology associated with public speaking anxiety. Secondary outcome measures will be the severity of depressive and anxious symptomatology, quality of life, usability, and perceived acceptance of participants.

Individuals will be assessed thrice: at baseline, post-treatment, and 3-month follow-up.

Data will be analyzed both per protocol and intention-to-treat. This study will pioneer this type of intervention by bringing together an underdeveloped concept with implementing new technologies. It is intended to increase our knowledge about treatments administered through the Internet and will contribute to improving the dissemination of treatments.

Arm && Interventions

Group	Intervention	Description
Emotional Reasoning bias correction training	Emotional Reasoning bias correction training	The experimental arm will receive an Emotional Reasoning bias correction training. The training consists of 12 self-administrated sessions, delivered online.
Intervention based on mindfulness	Module of Mindfulness of the Transdiagnostic treatment	The control group refers to an intervention based on mindfulness skills. This treatment is part of a Transdiagnostic treatment developed in our laboratory, for the treatment of patients with emotional disorders (Díaz-García et al., 2017).

Primary Outcome Measures

Name	Time	Method
Changes in ERPSAS Emotional Reasoning Public Speaking Anxiety Scale	3 evaluations: at baseline before treatment onset, at treatment completion on the 13th day (Post-treatment evaluation) and 3-month follow up. Changes will be evaluated from pre-treatment to post-treatment and from post-treatment to 3 month follow-up.	ERPSAS is a self-report instrument consisting of the presentation of 4 scenarios with different endings depending on whether objective safety or danger information is presented and whether there is an anxiety response or not. Based on these scenarios the participant must measure, on a visual analog scale (VAS) from 0 to 100, the degree of danger, safety, controllability, desire to avoid the situation and degree of discomfort. The sum of these scales provides a single perceived threat score providing a measure to determine the presence of the Emotional Reasoning Bias. If the participant evaluates emotional situations as threatening without objective information of danger, the presence of an Emotional Reasoning bias arises. The scale has a range of 0-96 points (M= 36.57; SD= 14.18). The higher the score, the greater the emotional reasoning bias, with the cut-off point being a score of 47. Participants scoring above half a standard deviation above the mean will be included.
Changes in Public Speaking Anxiety Scale	3 evaluations: at baseline before treatment onset, at treatment completion on the 13th day (Post-treatment evaluation) and 3-month follow up. Changes will be evaluated from pre-treatment to post-treatment and from post-treatment to 3 month follow-up.	The Public Speaking Anxiety Scale, which contains 17 items with a 5-point Likert-type response format (1=Not at all, 5=Extremely). This scale measures the presence and severity of cognitive, behavioural, and physiological symptomatology related to fear of public speaking, with a cut-off point of 73 (M= 49.33; SD= 12.88). Participants scoring above half a standard deviation above the mean will be included.

Secondary Outcome Measures

Name	Time	Method
Changes in Overall Anxiety Severity and Impairment Scale	3 evaluations: at baseline before treatment onset, at treatment completion on the 13th day (Post-treatment evaluation) and 3-month follow up. Changes will be evaluated from pre-treatment to post-treatment and from post-treatment to 3 month follow-up.	OASIS is a 5-item self-report instrument that assesses a unidimensional factor related to the severity and frequency of anxiety symptoms, as well as behavioral avoidance and functional impairment associated with these symptoms in the past week. Each item has five response options, coded from 0 to 4. The total score is calculated by adding the values of all items, ranging from 0 to 20. Scores higher than 8 indicate the presence of anxiety symptoms. This scale has been validated online in a sample of patients with depression and anxiety, demonstrating good internal consistency (α=0.86), as well as adequate convergent and discriminant validities, and sensitivity to change.
Changes in Quality Life Index	3 evaluations: at baseline before treatment onset, at treatment completion on the 13th day(Post-treatment evaluation) and 3-month follow up. Changes will be evaluated from pre-treatment to post-treatment and from post-treatment to 3 month follow-up.	The QLI is a 10-item self-report instrument that assesses a single concept of quality of life across 10 dimensions using a ten-point Likert scale (1=poor; 10=excellent). The dimensions include physical well-being, psychological/emotional well-being, self-care and independent functioning, occupational functioning, interpersonal functioning, social-emotional support, community and services support, personal fulfillment, spiritual fulfillment, and overall perception of quality of life. The total score is the average of the item scores, ranging from 1 to 10 (1-4.5 = below average quality of life; 4.6-8.1 = average quality of life; 8.2-10 = above average quality of life). The QLI demonstrates high internal consistency (α=0.89) and test-retest reliability (0.89), with discriminant validity evidenced in a sample of psychiatric patients.
Changes in Overall Depression Severity and Impairment Scale	3 evaluations: at baseline before treatment onset, at treatment completion on the 13th day (Post-treatment evaluation) and 3-month follow up. Changes will be evaluated from pre-treatment to post-treatment and from post-treatment to 3 month follow-up.	ODSIS is a 5-item self-report instrument that the severity and functional impairment linked to depression over the past week. Each item has five response options coded from 0 to 4. The total score is calculated by summing the values of all items, ranging from 0 to 20. Scores of 5 or above suggest depressive symptoms. This scale was validated online using a sample of patients with depressive or anxiety disorders. It demonstrates excellent internal consistency (α=0.92), and its construct, convergent, and discriminant validities are supported.
Score in Satisfaction and acceptance with the training	2 evaluations: at post-treatment (just after treatment completion on the 13th day) and at 3-month follow up.	Satisfaction and acceptance with the training will be assessed using questions developed by our team and previously used in studies with technology (Suso-Ribera, Castilla, Zaragozá, Ribera-Canudas, Botella, \& García-Palacios, 2018). Examples of items include "To what extent are you satisfied with the intervention?" and "To what extent would you recommend the intervention?".
Score in System Usability Scale	2 evaluations: at post-treatment (just after treatment completion on the 13th day) and at 3-month follow up.	The SUS is a 10-item self-report instrument designed to assess opinions on system usability using a 5-point Likert scale ranging from 1 (Completely disagree) to 5 (Completely agree). The content validity index of the Spanish version of the SUS was favorable, with a rating of 0.92 for item relevance. The Cronbach's α was 0.812.
