About

The objectives of the study are to 1) to translate and adapt iCBT Shyness Program to the Canadian context; 2) to examine the completion and effectiveness of the Canadian adapted, including the French translated and English iCBT Shyness Program, in improving SAD symptoms; 3) to explore barriers and facilitating factors to the program's implementation. The overall study design is a hybrid effectiveness-implementation study of a quasi-experimental parallel group trial reflecting real world pathways (recommended and self-referrals). The project will be conducted in two Canadian provinces: Quebec (Montérégie) and Ontario. Prior to implementing the iCBT Shyness Program, it will undergo an initial adaptation to the Canadian context and focus groups will be conducted with key actor groups to discuss the adaptations to the graphics, narration of the modules, and this to better reflect varying sociocultural context among Canadian French- and English-speaking populations. We will then evaluate the outcomes associated with the implementation of the program in a three-pathway parallel trial. As a last step to this trial, semi-structured interviews will be conducted with study participants and health care providers to explore facilitating factors and barriers to the implementation of the iCBT adapted program.

Full description

Study rational Social anxiety disorder (SAD) is one of the most prevalent anxiety disorders, with lifetime and past-year prevalence estimates reaching 12% and 7% in Canada. In the absence of treatment SAD is a chronic disorder with significant impairment in functioning associated with reduced school performance, loss of productivity, and decreased quality of life. During COVID-19, studies highlight increased mental health needs, but barriers to mental health service access due inpart to limited resources available. Viable therapy options for the treatment of SAD include CBT being delivered virtually, with effectiveness being shown in youth and adults. The Clinical Research Unit for Anxiety and Depression (CRUfAD) in Australia has developed, implemented, and demonstrated the effectiveness of an innovative guided and unguided internet delivered cognitive-behavioural therapy (iCBT) program for social anxiety. To make available high-quality and real-time evidence in response to the current COVID-19 mental health crisis and crucially needed access to psychological services to meet population mental health needs including for high risk populations (including individuals with pre-existing psychiatric conditions, youth and young adults, self identifying as belonging to a visible minority group (including from linguistic minority groups), we propose to conduct a Canadian adaptation of Australia's Shyness Program and to examine the adapted program's effectiveness, and implementation in two Canadian provinces (Quebec and Ontario).

Objectives

1. to translate and adapt iCBT Shyness Program to the Canadian context; 2) to examine the completion and effectiveness of the Canadian-adapted, including the French translated and English iCBT Shyness Program, in improving SAD symptoms; 3) to explore barriers and facilitating factors to the program's implementation.

Methods

The overall study design is a hybrid effectiveness-implementation study of a quasi-experimental parallel group trial reflecting real world pathways (recommended and self-referrals). The project will be conducted in two Canadian provinces: Quebec (Montérégie) and Ontario.

To build on the current knowledge regarding the effectiveness of guided and unguided iCBT for SAD and inform on generalizability, we will evaluate the outcomes associated with the implementation of the program in a three-pathway parallel trial. The iCBT Shyness Program includes six online lessons based on CBT strategies with homework assignments to be completed within 90 days. The study will be carried out in Quebec and Ontario.

Phase 1:

Prior to implementing the iCBT Shyness Program, it will undergo an initial adaptation to the Canadian context. Focus groups in each province will be conducted with key actor groups (patients-partners, community leaders, service providers, i.e., consultant-partners to the research team) to discuss the adaptations to the graphics, narration of the modules, and this to better reflect varying sociocultural context (e.g., socioeconomically disadvantaged environment; cultural backgrounds) among Canadian French- and English-speaking populations.

Phase 2:

Then, individuals with social anxiety will either: 1) self-refer to the adapted intervention (self referral, undirected iCBT); 2) be recommended the adapted intervention by a registered health professional and will complete the program without guidance (recommended, undirected iCBT); or 3) be recommended the adapted intervention by a registered health professional, with low intensity guidance throughout the program (recommended, directed iCBT). The program will be implemented via the virtual clinic at Université de Sherbrooke (www.equilia.ca), as we have acquired and implemented a license for the virtual clinic in Canada. Data collection will be integrated into the virtual clinic web platform and the REDCap platform and carried out at baseline, at the beginning of each lesson, 12-week and 6-month follow-up. Individual-level outcomes measured will include anxiety and depressive symptoms, psychological distress, disability, health-related quality of life as well as health service utilization and satisfaction.

Phase 3:

As a last step to this trial, semi-structured interviews will be conducted with study participants and health care providers to explore facilitating factors and barriers to the implementation of the iCBT adapted program, and this to inform implementation strategies for wider use across Canada.

Anticipated results

This study will provide evidence on the effectiveness, barriers and facilitating factors to implementing a low-intensity iCBT in the Canadian context for SAD, which will bridge an important care gap for undeserved populations in Canada with SAD. Findings will inform the eventual scaling up of the program in community-based primary health care across Canada. This would improve equity of the health care system by helping a large number of Canadians including those from visible, socio-cultural, and linguistic minority groups timely access to mental health services post-pandemic.

Masking: None (Open label)

---

252 participants in 3 patient groups

Self-referred, undirected iCBT

Experimental group

Description:

These individuals will do the program, but will not receive follow-up contact during the program. In case of severe psychological distress (i.e. score ≥30 on Kessler's 10-item psychological distress scale (K10), participants will receive an automated email with a list of resources and emergency contact numbers.

Treatment:

Behavioral: Self-referred, undirected Internet-based cognitive behavioral therapy for social anxiety

Recommended, undirected iCBT

Experimental group

Description:

Participants will have received the recommendation from a healthcare professional (e.g., family physician, nurse or social worker, psychologist) to complete the adapted program without guidance. Clinicians will provide the name and email of the patients they are referring the program to without providing participants with in-program support but will consult the dashboard as they have clinical responsibility for the patient. In case of severe distress (i.e., K10 score ≥30), the referring healthcare professional will receive an automated email informing them to go to their dashboard to identify that patient. Participants will also receive an automated email with a list of resources and emergency contact numbers. To support the generalization of findings to the real-world (ecological validity), clinicians may follow-up with patients at their discretion.

Treatment:

Behavioral: Recommended, undirected Internet-based cognitive behavioral therapy for social anxiety

Recommended, directed iCBT

Experimental group

Description:

Participants will be recommended the intervention by a healthcare professional and be provided low-intensity guidance (e.g., email or brief phone contact \[5 to 10 minutes\] after Lesson 1 and 2, and then on an as-needed basis or patient request). Clinicians at the primary care sites participating in the study will be able to recommend the adapted program to their patients, will remain responsible for their patients and, will check their dashboard to see how their patients are progressing through the program. In the event of severe distress (i.e., K10 score ≥30) in a patient, the referring healthcare professional will receive an automated email informing them to go to their dashboard to identify that patient and assess the appropriate action to take. Participants will also receive an automated email with a list of resources and emergency contact numbers.
