Internet-Delivered Self-help for Adults With ADHD (MyADHD): Usability Study.

Area of Science:

• Digital Health
• Human-Computer Interaction
• Psychiatry

Background:

• Many adults with attention-deficit/hyperactivity disorder (ADHD) prefer non-pharmacological management options.
• Internet-delivered self-help interventions offer a potentially low-cost solution for ADHD symptom management.
• Optimizing usability is crucial for adherence, engagement, and effectiveness of digital interventions.

Purpose of the Study:

• To evaluate the usability of the MyADHD internet-delivered self-help intervention for adults with ADHD.
• To collect qualitative and quantitative data on the intervention's usability.
• To identify specific usability problems and areas for improvement.

Main Methods:

• Usability testing involved individual think-aloud interviews with 5 end-users.
• Participants performed tasks within the MyADHD intervention and provided real-time feedback.
• Post-session ratings and verbatim transcript analysis were used to assess functionality, content, and design.

Main Results:

• Overall participant satisfaction with the MyADHD intervention's usability was high.
• Perceived usability scores improved from 70 to 77.5 after iterative modifications.
• Key themes identified for enhancement included design, functionality, and content.

Conclusions:

• Optimizing usability is essential for internet-delivered self-guided interventions.
• User feedback from this study provided critical insights for intervention refinement.
• The MyADHD intervention is user-validated and ready for further clinical trials.
