ABSTRACT

Background:

Online self-help interventions like MyADHD have the potential to address the unmet supportive care needs reported by adults with ADHD. However, if the intervention does not offer optimal functions, content and layout users may cease to use it.

Objective:

This study evaluates the usability of an Internet-delivered self-help intervention for adults with ADHD (MyADHD).

Methods:

Individual think-aloud interviews and staged usability testing (N=5) were conducted to evaluate usability of MyADHD intervention. MyADHD end-users provided iterative feedback to maximize engagement and usability. They performed tasks involved in operating the intervention and provided ‘think aloud’ commentary and post-session usability ratings. The interviews were recorded, transcribed verbatim and analyzed.

Results:

Participants were satisfied with the overall usability of the program. The average usability score was 70/100 for the first round of testing and improved to 77.5/100 after applying modifications, with a mean score of 75.5 (Sd=5.9). The analysis of the interviews revealed three central themes: functionalities, content, and lay out.

Conclusions:

Optimizing the usability of Internet-delivered self-guided interventions is a critical step in the design and development process. The usability testing in this study provided valuable information from users’ perspective and through an extensive development process, we produced an intervention that is likely to be used successfully and is ready for deployment in randomized controlled trial.
