Digital mental health intervention for schizophrenia spectrum and psychotic disorders: Protocol for a pragmatic feasibility study of Horyzons-Canada

Background Schizophrenia spectrum and other psychotic disorders (SSPD) are among the most debilitating of all mental disorders. While the evidence for psychosocial interventions such as cognitive behavioral therapy and peer support has significantly improved, access to these services remains limited. This paper describes a protocol for a pragmatic feasibility study of a digital mental health intervention (HoryzonsCa) that provides access to evidence-based psychosocial interventions, social networking, and clinical and peer support services through a secured, web-based platform for adults diagnosed with SSPD. Objective The objectives are: (1) Adapt and translate HoryzonsCa for implementation in English and French; (2) Develop an implementation and training strategy; (3) Assess the acceptability, safety, and demand of HoryzonsCa; (4) Assess clinical outcomes and perceived impacts; (5) Examine the experiences and process of adapting and implementing HoryzonsCa; (6) Explore the role of sociocultural and demographic factors on HoryzonsCa outcomes and implementation. Methods This feasibility study will use a single-group, pre-post, mixed-methods (QUAN–QUAL convergent) research design, with assessments at baseline and 12 weeks. The study aims to recruit 100 individuals (ages 18–50) diagnosed with SSPD from two healthcare settings in Canada. Data collection includes interview-based psychometric measures, self-reports, focus groups, and interviews with participants. The study will also collect qualitative data from moderators and the research team, and will be conducted entirely remotely. Conclusions This study has been prospectively registered and is underway. It will provide timely information on the feasibility and potential impacts of using digital mental health services for individuals with chronic mental health conditions.
