Background: Many people at risk of suicide do not seek help before an attempt. mHealth
interventions are proposed as an effective means of addressing the two main obstacles to
help seeking in suicidal individuals: stigma and geographical isolation. This study describes
a collaborative project between CAATCH, a community-based suicide prevention initiative
and the National University of Ireland, Galway, in the design, development and evaluation of
a suicide-prevention app. The CAATCH app is freely available to download on both the
Android and iOS platforms.
Methods: The process of app development was informed by key standards in content
development and software design. Steps involved included: a review of research and theory
relevant to the area; involvement from community services and subject matter experts, user
engagement in designing and developing the app followed by extensive ongoing evaluation
to inform further development. A cross-sectional design was used with over 200 university
students recruited to evaluate features of the CAATCH mobile app and provide feedback to
inform development of the next version of the app.
Results: Over two thirds of participants would recommend the app and over three quarters
rated the app as being easy to use. Further information is presented relating to specific
features of the app and suggestions for future development.
Conclusions: A comprehensive evaluation of the CAATCH app has so far yielded valuable
information about the app including ease of use and relevance of content provided. Detailed
feedback was collected which will be used to inform the development of CAATCH v.2.
