ABSTRACT
BACKGROUND: Smartphone apps have potential for delivering interventions and supporting self-management in bipolar disorder (BD), however clinical trials of mental health apps have high dropout rates and low sustained use in real-world contexts. To support the development of app-based interventions, we explored use of and attitudes towards apps amongst people with BD, specifically concerns about privacy and preferences for various app features. METHODS: An international web-based survey was used to investigate concerns about privacy and the perceived importance of various app features among people with BD. Quantitative findings were summarised using descriptive statistics. Qualitative content analysis was used to investigate free-text responses. RESULTS: A total of 919 people completed the survey; 97.5% reported using smartphone apps in general. Concerns regarding data security were prevalent. Commonly prioritised mHealth features included content quality/accuracy, ease and flexibility of use, cost, and data security. The ability to share data with others, rewards for use, inter-app connectivity, and peer support were endorsed as important by fewer than half of respondents. Qualitative findings suggested that sustained app use could be supported by novel and positive content, customisation, meaningful use of data, interactivity, and perceived real-world benefits. CONCLUSIONS: The findings of the present study offer important design considerations for the development and evaluation of future app-based interventions for BD. Importantly, some features that have previously been suggested as clinically beneficial or likely to support engagement were perceived ambivalently, emphasising the need for in-depth consultation with potential end users during app development.
