Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
\--------------
Background:
\--------------
The investigators' research unit, PSPNET, is currently providing therapist-guided internet-delivered cognitive behavioural therapy (ICBT) to public safety personnel (PSP) in the Canadian provinces of Saskatchewan, Quebec, Nova Scotia, and New Brunswick. Specifically, PSPNET is offering PSP a transdiagnostic ICBT program for depression, anxiety, and PTSD (the PSP Wellbeing Course), as well as a disorder-specific ICBT program for PTSD (the PSP PTSD Course). ICBT is effective and can help overcome many of the barriers to traditional, face-to-face mental healthcare that PSP face (e.g., concerns about privacy, stigma, distance from services, cost of treatment).
The investigators have created an unguided version of the PSP Wellbeing Course (i.e., no therapist guidance) called the Self-Guided PSP Wellbeing Course. They plan to evaluate this ICBT program through a randomized trial across Canada. Although unguided ICBT does not tend to be quite as effective as guided ICBT, it still consistently results in favorable outcomes compared with control conditions. An important advantage of unguided ICBT is its greater scalability-that is, once created, an unguided ICBT program can be delivered easily on a large scale. Given that PSP face many barriers to mental healthcare, it is expected that participation in this study will help extend treatment to individuals who have not been able to access traditional, face-to-face mental healthcare services. Further, participants will be free to access any other services they see fit while participating in this research.
Prior studies evaluating unguided ICBT interventions that have included online discussion forums have demonstrated excellent results, in many cases finding outcomes comparable to those found in trials of guided ICBT and face-to-face therapy. However, no prior study has experimentally tested the impact of adding an online discussion forum to an unguided ICBT intervention.
The objectives of this new proposed study are (a) to evaluate the first-ever transdiagnostic, unguided ICBT program tailored for PSP, (b) to conduct the first experiment assessing whether a therapist-moderated online discussion forum (hereafter described as the "Peer Support Forum", as it will be known to participants) affects outcomes, and (c) to conduct a mixed-methods analysis of participant feedback on the discussion forum to inform future efforts to implement discussion forums in ICBT. This will be done using a randomized trial comparing the Self-Guided PSP Wellbeing Course with a version of the Self-Guided PSP Wellbeing Course that includes the Peer Support Forum. Participants assigned to the condition with the Peer Support Forum will be encouraged to discuss the course with each other and support one another in using it throughout their participation in the study.
This project is expected to have four implications: (a) to provide treatment to the PSP who participate in it; (b) to inform the potential future use of unguided ICBT for PSP; (c) to experimentally assess whether adding an online discussion forum to an unguided ICBT intervention improves outcomes, and (d) to assess what participants like and dislike about online discussion forums within the context of an ICBT intervention to help guide the future implementation of online discussion forums in ICBT.
\--------------
Overview of Methods:
\--------------
The proposed research will consist of a randomized trial (N = 114) with two conditions, both of which will involve an eight-week, transdiagnostic unguided ICBT intervention tailored for Canadian PSP. One condition will consist of the ICBT intervention only ("ICBT-Only condition"), and the other will consist of the ICBT intervention with a therapist-moderated online discussion forum ("ICBT + Peer Support Forum condition"). Participants will be administered a battery of self-report measures during eligibility screening and at eight and 20 weeks post-enrollment. Primary outcomes will include changes in symptoms of depression, anxiety, and posttraumatic stress disorder. Secondary outcomes will include treatment satisfaction, treatment engagement, patient-program alliance, and changes in health service use, resilience, subjective wellbeing, and functional impairment. Treatment outcomes will be compared across the two conditions using multilevel modeling. The investigators will also use qualitative analysis to further examine treatment satisfaction and participants' experiences with the Peer Support Forum. Of note, the sample size (N = 114) was calculated as a minimum acceptable sample size, and the investigators plan to recruit more participants if possible, given the uncertainty around the size of effect they may ultimately find.
\--------------
Measures:
* Change in symptoms of depression (PHQ-9)
* Change in symptoms of anxiety (GAD-7)
* Change in symptoms of PTSD (PCL-5)
* Change in resilience (BRS)
* Change in wellbeing (FS)
* Change in healthcare use (Healthcare Use Questionnaire)
* Treatment satisfaction (Treatment Satisfaction Questionnaire)
* Patient-program alliance (SRS)
* Demographic information (Participant Information Questionnaire)
* Knowledge and perceptions of ICBT)
* Alcohol use (AUDIT)
* Drug use (DUDIT)
Procedure:
\--------------
To enroll in the proposed study, PSP will access a study web page that will provide some basic information about the study. Interested PSP will then click a link to access the study consent form. It is not possible for participants to be blinded to their condition in psychotherapy research, but the consent form will describe the study only in general terms (e.g., it will not mention the Peer Support Forum) so that each participant can be kept blind to how their condition differs from others. Prospective participants who provide informed consent will be administered the Participant Information Questionnaire, PHQ-9, GAD-7, PCL-5, BRS, FS, AUDIT, DUDIT, Health Service Use Questionnaire (screening version), and ICBT Feedback Questionnaire. Prospective participants who are under the age of 18 will immediately and automatically be notified that they are ineligible to participate. Otherwise, participant eligibility will be reviewed by the principal investigator and/or a research assistant. Eligible participants will be randomly assigned to conditions using the website randomizer.org and manually enrolled in one of the two versions of the Self-Guided PSP Wellbeing Course (i.e., the ICBT-Only version or the ICBT + Peer Support Forum version). Due to concerns that psychosis, mania, or substance abuse could interfere with participants' ability to engage in the Peer Support Forum in a constructive way, eligible participants reporting these characteristics will be nonrandomly assigned to the ICBT-Only condition and excluded from the main analyses.
Participants will receive an email informing them that they have been assigned to a condition and may begin the Self-Guided PSP Wellbeing Course on the next Monday. Individuals who are ineligible to participate but 18 years of age or older will receive an email informing them that they are ineligible to participate in the study but may receive access to the treatment content without being part of the study if they wish. This procedure is expected to provide a disincentive for prospective participants who are deemed ineligible to attempt to enroll again using deceptive responses to the screening questionnaires. The investigators will send login information to participants and nonparticipants who are given access to the treatment materials by email. Upon logging in for the first time, prospective participants will immediately be prompted to change their passwords. Participants will be given access to the Self-Guided PSP Wellbeing Course, and participants assigned to the ICBT + Peer Support Forum condition will be given access to it through a link embedded in their version of the course. Before accessing the Peer Support Forum, they will be required to provide informed consent to engage in the Peer Support Forum and agree to the Forum Terms of Use.
Eight weeks after their date of enrolment-and again at 20 weeks after their date of enrolment-participants will receive an automated email asking them to complete posttreatment questionnaires. Participants will provided informed consent to continue their participation in the study before completing these questionnaires. The posttreatment questionnaires will include the PHQ-9, GAD-7, PCL-5, BRS, and FS. At eight weeks, but not at 20 weeks, participants will also be asked to complete the Health Service Use Questionnaire (posttreatment version), adapted SRS, and Treatment Satisfaction Questionnaire. Participants will be asked to complete these measures within four weeks of them being made available. Participants will also be asked to complete an extremely brief Program Usage Questionnaire at 2, 4, 6, and 8 weeks. Participants will be able to access the Self-Guided PSP Wellbeing Course (and the Peer Support Forum, for participants who are granted access to it) for 20 weeks after their date of enrolment.
\--------------
Peer Support forum:
\--------------
All participants assigned to the ICBT + Peer Support Forum condition will be given access to the same forum (i.e., there will not be multiple forums). The Peer Support Forum will be moderated by the principal investigator, with support from PSPNET's team of registered therapists as necessary. The principal investigator will check the forum daily and post comments as appropriate to facilitate discussion. The number of comments the principal investigator will post and the amount of time spent moderating the Peer Support Forum will depend on the level of activity in the forum and will be documented and reported. The principal investigator has a master's degree in clinical psychology.
The Peer Support Forum will include a Terms of Use page that will be prominently displayed for participants to review. The forum will include several sections, and participants will not be able to add new sections. Within each section, however, participants will be able to add topics and respond to topics via posts. That is, posts are nested within topics, which are in turn nested within sections. The Peer Support Forum will include the following seven sections: one for each of the five lessons of the Self-Guided PSP Wellbeing Course, one for clients who have completed all lessons, and a miscellaneous section. Additional sections may be added during the course of the study as necessary.
In addition to being able to create topics and posts in the Peer Support Forum, participants will be able to flag posts to alert the moderating therapist to inappropriate content. Flagged posts will be hidden until the moderator reviews them, with a note stating that they have been flagged due to a potential violation of the Terms of Use. The moderator will then decide whether a flagged post is in violation of the Terms of Use, in which case it will remain hidden, or whether it should be made visible again. Participants will also be able to create nicknames for themselves that will appear on the topics and posts they create. The Terms of Use urge participants to avoid using any self-identifying information within their chosen nickname. If a participant chooses a nickname that reveals their identity, a member of the PSPNET team will email the participant to ask them to change it.

Participants will be randomly assigned to one of two treatment conditions (unguided ICBT only or unguided ICBT + online discussion forum)
Primary Study Purpose

Blinding Strategy
NONE
Participants cannot be blinded to condition because ICBT (like other psychotherapies) cannot be both provided to and concealed from a participant. However, the difference between the two conditions (i.e., presence or absence of an online discussion forum) will be concealed from all participants. Because only participants assigned to the ICBT + Peer Support Forum condition will have access to the Peer Support Forum, it will not be possible to mask the forum moderator to those participants' condition. Because outcomes will be assessed via self-report questionnaire measures, outcomes assessor masking is not possible.
