Introduction: Mindfulness-based programs are a promising option for patients with attention-deficit/hyperactivity disorder (ADHD), who face attention, hyperactivity, and emotion dysregulation issues in their daily life.

Objective: To examine the implementation and impact of specific mindfulness training for adults with ADHD in a French-speaking unit.

Methods: Thirty-eight adults with ADHD were included in an 8-week Mindful Awareness Practices (MAPs) program. Patients were assessed for ADHD symptoms, anxiety, depression, and mindfulness skills, before (T1) and after (T2) the eight sessions, and then 2 months later (T3).

Results: The patients adhered to the program as the majority of them completed it. A significant decrease in ADHD, depression, and anxiety symptoms was found between T1 and T2. Regarding mindfulness skills, a significant increase was observed between T1 and T2 in Observing, Describing and Nonreactivity to inner experience cores, but not Acting with awareness and Nonjudging of inner experience scores. There was no significant change between T2 and T3.

Conclusion: The MAPs program was successfully implemented and showed promising effects on ADHD symptomatology and related symptoms.
