Attention-deficit/hyperactivity disorder (ADHD) is a controversial diagnosis that is debated in public and professional spheres. However, the experiences of Aboriginal peoples have largely not been included in this debate. Considering that reactions to trauma may include hyperactivity and attention-deficits, and that mental health is defined differently in different cultures, this is arguably problematic. This research uses a qualitative exploratory approach embedded in an anti-oppressive social work research framework to explore the experiences of four urban Aboriginal mothers of children diagnosed with ADHD in Northern British Columbia. It was found that Aboriginal caregivers experience many challenges already recorded in the literature, and that they also grapple with the impacts of colonialism and intergenerational trauma in different ways. When considering the principles of allyship and anti-oppressive practice, this raises ethical questions about where the burden of responsibility lies, as well as how ADHD is currently defined and used in practice.
