Little research on assistive technologies for families of children with attention deficit hyperactivity disorder (ADHD) has investigated the long-term impact, after the assistive technology is returned to the researchers. In this paper, we report the outcomes of a follow-up study, conducted four-weeks after a field study of 13 children with ADHD and their families who used an assistive technology designed to help establish and change family practices. We show that some of the positive effects on parent frustration level and conflict level around morning and bedtime routines that we observed in the first phase of the study, continued even after the study period, when the technology was no longer available. We furthermore present insights into family practices in families of children with ADHD and how these could lead to unexpected challenges and implications related to the adoption, use, and outcome of the assistive technology.
