The experiences of receiving a diagnosis of attention deficit hyperactivity disorder during adulthood in Japan: a qualitative study

Although the number of adults with attention deficit hyperactivity disorder (ADHD) has increased considerably in recent years, there are few qualitative investigations of the experiences of adults with adult-diagnosed ADHD in Japan. This study aimed to explore in depth the diagnosis-related experiences and needs of such adults. Participants were 12 psychiatric outpatients aged 23–55 years diagnosed with ADHD during adulthood. Individual semi-structured interviews were conducted to examine participants’ experiences of receiving, and subsequently coping with, an ADHD diagnosis. A thematic analysis of the interview data was performed. Six themes emerged: difficulties in accepting the diagnosis, interest in ADHD, feelings of relief, identity concerns, dealing with symptoms, and acceptance of ADHD. Despite initial negative reactions, participants were willing to learn about the disorder, spending time seeking ADHD-related information and sharing it with loved ones. Participants felt relieved after the diagnosis, as they realized why they had experienced long-term problems and incorrect labeling. However, participants also had identity concerns. They gradually began to accept their ADHD symptoms and deal with them better. The results suggest that, when treating individuals with adult-diagnosed ADHD, it is important to promote self-understanding and reduce negative attitudes toward ADHD; to provide appropriate, brief, evidence-based information about ADHD; and to give individuals sufficient time to think about their ADHD symptoms, how they have affected their daily lives, and how to cope with them in the future.
