BACKGROUND

Quality of life (QoL) is increasingly recognised as a key outcome of self-management interventions for bipolar disorder (BD). Mobile phone applications (apps) can increase access to evidence-based self-management strategies and provide real-time support. However, while individuals with lived experience desire support with monitoring and improving broader health domains, existing BD apps largely target mood symptoms only. Further, evidence from the broader mHealth literature has shown that the desires and goals of end-users are not adequately taken into account during app development, and as a result engagement with mental health apps is suboptimal. To capitalise on the potential of apps to optimise wellness in BD, there is a need for interventions developed in consultation with real-world users that are designed to support QoL self-monitoring and self-management.

Objective: This mixed methods pilot study is designed to evaluate the beta version of the newly developed PolarUs app, which aims to support QoL self-monitoring and self-management in people with BD. Developed using a community-based participatory research framework, the PolarUs app builds on the web-based adaptation of a BD-specific QoL self-assessment measure, and integrates material from a web-based portal providing information on evidence-informed self-management strategies in BD.

OBJECTIVE

The primary objectives of this project are to: (1) evaluate PolarUs app feasibility (via behavioral usage metrics); (2) evaluate PolarUs impact (via the Brief Quality of Life in Bipolar Disorders, QoL.BD scale, our primary outcomes measure); and (3) explore engagement with the PolarUs app (via both quantitative and qualitative methods).

METHODS

Study participants will be North American residents (N=150) aged 18-65 years with a DSM-5 diagnosis of BD-I, BD-II or BD not otherwise specified (NOS) as assessed by a structured

diagnostic interview. An embedded mixed-methods research design will be adopted; qualitative interviews with a purposefully selected sub-sample (~n=30) of participants will be conducted to explore in more depth feasibility, impact and engagement with the PolarUs app over the 12-week study period.

RESULTS

At the time of publication of this protocol, the development of the beta version of the PolarUs app is complete. Participant enrollment is expected to begin in February 2022. Data collection is expected to be completed by December 2022.

CONCLUSIONS

Beyond contributing knowledge on the feasibility and impacts of a novel app to support QoL and self-management in BD, this study is also expected to provide new knowledge on engagement with mHealth apps. Furthermore, it is expected to function as a case study of successful co-design between individuals living with BD, clinicians who specialise in the treatment of BD, and BD researchers, providing a template for future use of community-based participatory research frameworks in mHealth intervention development. Results will be used to further refine the PolarUs app and inform the design of a larger clinical trial.
