Diversity and attention deficit hyperactivity disorder.

Attention Deficit Hyperactivity Disorder (ADHD) is a debilitating disorder which affects children and adults in this country and around the world. Diversity variables such as ethnicity, age, gender, and socioeconomic status have been relatively neglected in ADHD research. Additionally, these variables have not traditionally been incorporated into clinical assessment, diagnosis, or intervention strategies. A review of the existing literature regarding diversity issues and ADHD was conducted, including a review of international findings. Implications for clinicians and researchers are incorporated.
