Mental health systems in developed countries need innovating because they are not meeting demands. The use of the Internet and associated technologies in the provision of mental health services and supports, also known as eMental Health (eMH), has been increasingly looked at as a key source of such innovation. Research into eMH has primarily been driven by an interest in online technologies as novel means of treatment delivery with the potential of making established psychological mental health treatments more widely available and accessible. However, eMH research has prioritised the knowledge generated through clinical trials of online mental health treatments, largely overlooking people’s usage and experience of online treatments and supports in real life. Understanding the nature of use of these resources by individuals with mental health problems in their everyday lives is crucial to designing online supports that are relevant to the real-life help-seeking needs of people with mental health problems. This study has addressed this gap by exploring how adults with a mental health problem use online mental health resources in their everyday lives and what is the role of technology in the experience of seeking mental health support in this way. Using a mixed methods methodology and design integrating the results of an online questionnaire (109 participants) with the results from 10 semi-structured interviews, this study’s findings support the need for a pluralistic ecosystem of mental health services and supports where both traditional in-person services and alternative forms of support and modes of access are provided. The findings offer support for the potential of online mental health tools to be one such alternative and a way for mental health systems to expand and diversify available options for support, achieve better inclusivity of people’s diverse support needs, and better support their autonomy in seeking help.
