This is a mixed methods study that evaluates the effectiveness of the Big White Wall (BWW) online community and its implementation in 3 hospital/health system sites across Ontario. The 6 month study includes 1000 participants that are randomized to an immediate treatment group or a delayed treatment group. The primary outcome includes a change in total and subscale scores on the Recovery Assessment Scale. Qualitative interviews with various stakeholders will explore issues relating to successful implementation.
The study consists of a pragmatic randomized controlled trial (RCT) with a nested comparative effectiveness arm to assess the value of intervention extension, with concurrent Realist Evaluation. The pragmatic randomized trial will assess whether the intervention (the Big White Wall) works when introduced into a public health or clinical setting, i.e., in real life conditions. The qualitative realist evaluation will assess the contextual influences and strategies by which the Big White Wall is adopted or rejected.
1. Pragmatic Randomized Control Trial (RCT) with nested comparative effectiveness arm:
The RCT will include a delayed treatment crossover control. The immediate treatment group (ITG) will get access to the BWW at time of enrollment and have continuous access for a period of 3 months. The delayed treatment group (DTG) will have no access for the first 3 months, then receive access to the BWW for 3 consecutive months. A 2:1 allocation ratio will be used to randomized participants to ITG or DTG. After 3 months of intervention, ITG participants will have the opportunity to opt-in to an intervention extension arm. Those who opt-in will be randomized at a 1:1 ratio to receive an additional 3 months of BWW or no additional intervention.
The investigators hypothesize that users of the BWW will experience an increase in their mental health recovery orientation as evidenced using a standardized recovery assessment tool. The investigators also hypothesize that improvements will be observed in symptoms of depression and anxiety, along with quality of life and community integration.
A total of 1000 study participants will be recruited from 3 large mental health settings in Ontario: Ontario Shores Mental Health Sciences, Lakeridge Health, and Women's College Hospital (WCH). Lakeridge Health and Ontario Shores both have inpatient and outpatient mental health services that support individuals with mental health issues across the lifespan while Women's College Hospital has a large outpatient mental health program.
All study participants will be given access to the BWW, free of charge, for 3 months or 6 months for those randomized to the ITG extension arm. Services on the BWW include peer support, self-guided and facilitated self-help resources, psycho-educational material and interactive creative activities. All participants will maintain anonymity on the site through a unique non-identifiable user identifier (ID). All participants will receive a unique access code for the BWW. Use of the BWW is participant dependent, with the ability to log in and utilize the services at any frequency.
Baseline socio-demographic data will be collected following consent. Self-report data on all outcomes will be collected via questionnaires at baseline, 3 months and 6 months. Baseline outcome questionnaires will be completed in 1 of 3 ways: 1) web survey (default); 2) by phone; 3) in-person hard copy. All other questionnaires will be administered with web-based surveys.
Data analysis will be done at study completion, after all data has been collected. Analysis will be blinded to treatment allocation. Initially, descriptive analysis will be conducted for all variables. The primary outcome, The Recovery Assessment Scale-Revised (RAS-r) at 3 months, will be analyzed with an intent-to-treat analysis using an ANCOVA controlling for baseline RAS-r score as well as treatment group, unadjusted and adjusted for baseline Patient Health Questionnaire (PHQ-9), baseline Generalized Anxiety Disorder (GAD-7), age, sex, education, relationship status, household income, duration of episode, and recruitment setting. In sensitivity analysis, the investigators will repeat this using a marginal structural model to account for attrition. The same analysis will be repeated for all secondary outcomes at 3 months controlling for baseline score and treatment group. In the subset of ITG participants who opt in to the nested extension study, the investigators will examine outcomes at 6 months between treatment groups. Analysis of primary and secondary outcomes will be repeated as described above, controlling for scores at both baseline and 3 months. The first exploratory analysis will examine a subset of the ITG group who had a PHQ-9 or GAD-7 score of at least 10 at baseline. Participants will be categorized as 'responders' or 'non-responders' based on whether or not they achieved at least a 50% reduction in the PHQ-9 or GAD-7 at 3 months relative to baseline. Second, the investigators will examine engagement with the BWW among ITG participants. The number of logins and total time on the site will be separately predicted with age, gender, education, relationship status, living situation, household income, baseline belief in treatment credibility and outcome expectancy, baseline PHQ-9 and GAD-7 scores, duration of current episode, recruitment setting and outpatient mental health visits. In terms of economic evaluation, the combination of program costs, out-of-pocket costs and costs in the health care system will be used to determine the total costs associated with participants in the program. Incremental cost-effectiveness will be assessed using an incremental cost-effectiveness ratio calculated as the difference in costs between DTG and ITG divided by the difference in outcomes between these groups.
2. Qualitative Realist Evaluation Protocol The Realist Evaluation will occur alongside the pragmatic randomized trials described above, and will include two key methods. The first is qualitative interviews with key stakeholders involved in the implementation and use of BWW, and the second is observations of the introduction and use of the virtual care interventions among health care provider participants.
The objective of the qualitative realist evaluation component of this study is to (a) understand perspectives of mental health care providers regarding the appropriateness of BWW for their patients, (b) explore participants' perspectives of the usability and acceptability of the BWW online community, and (c) examine the key issues associated with scaling BWW up across Ontario.
At the time of recruitment into the broader pragmatic randomized trial of which this qualitative study is a part, patient participants will be asked if they consent to be contacted with further information regarding the qualitative element of the study. The qualitative research team will purposefully sample from the pool of interested ITG participants who consented to be contacted for an interview at study enrollment. The investigators aim to interview 4-6 participants at each site, spanning different age categories, for a total of 12-15 patient participants. Qualitative interviews will be completed with 5-7 health care providers at each site; 2-4 organizational leaders at each site (for example, clinical managers); and 5-7 health system decision makers in Ontario. These participants will be identified by clinical site leads using a snowball sampling process to identify key informants.
Patient interviews will be conducted via telephone or personal video conferencing. Patients will be invited to participate in two interviews 1-2 weeks after gaining access to the BWW and again at 8-12 weeks after gaining access. Observation of the educational session in which health care providers and other staff are educated regarding the BWW will take place. Participants who opt in for the intervention extension arm of the study will again be asked whether they are interested in participating in a qualitative interview. Participants who identify as willing to be contacted may or may not have participated in a qualitative interview in the first phase of the study, and will be purposefully sampled and interviewed 2-4 weeks after the re-randomization process in the same manner as the initial interviews. The investigators will again recruit 2-3 participants at each of the 3 sites for a total of 12-15 patient participants from the extension arm. Healthcare providers will also be invited to participate in an interview 1-2 weeks post-education session on the BWW. Health care provider interviews will take place at their location of work or via telephone. Organizational leaders will be invited to participate in an interview in person or via telephone 3 to 4 months post BWW implementation. Health system decision makers will be invited to participate in an interview in person or via telephone 3 to 6 months post BWW implementation. Patient interviews will include general questions about how the patient manages his or her mental health in the community, their perspectives of the BWW, and how they use the BWW. If the patient has not engaged with the BWW, the qualitative interview will include questions about why not, and what alternative strategies the patient uses to manage mental health in the community. Health care provider interviews will include questions about health care providers' perspectives on the BWW community, mental health services in Ontario, and the value of virtual care interventions such as the BWW for promoting self-management of mental health overall. Interviews with organizational leaders and health system decision makers will include questions about the effectiveness of virtual care interventions to promote mental health self-management in the community, the context of mental health services in Ontario, and the procurement and implementation of virtual care interventions such as the BWW.
Observation and interview data will be analyzed using thematic analysis strategies, identifying key themes that demonstrate important contextual influences and practices related to the implementation and evaluation of the virtual care technologies in actual contexts of health care delivery. The findings of the qualitative data will be used to develop statements of the relationships between (a) key contextual factors, (b) the mechanisms by which they effect the implementation of the virtual care interventions, and (c) the impact on the outcomes of the intervention themselves. These statements will be used to develop understanding of (a) the specific mechanisms by which BWW is effective for users, and (b) strategies to inform the future implementation of BWW and/or similar interventions on a larger scale.
