Abstract
Although numerous terms have been used to describe Attention-Deficit Hyperactivity Disorder (ADHD) during the past several decades, it has continued to be conceptualized from a biological or neurological perspective. Consequently, much research has accumulated investigating possible biological and neurological causes, developing better diagnostic criteria, and accumulating medication protocols. Despite voluminous amounts of research, little consensus has been reached as to the best way to define and diagnose ADHD. Consequently, it becomes difficult to generate and test hypotheses related to the etiology, characteristics, and treatment of this disorder. One problem relates to how ADHD is conceptualized. In approaching ADHD as a psychiatric condition, assessment usually focuses on improving diagnostic precision. Similarly, most treatment research has dealt with the use of psychopharmacological agents, such as Ritalin. Yet, there are many ways to conceptualize “disorders.” We begin this article by suggesting that ADHD has become reified as a result of social and cultural factors. We present an alternative conceptualization based on a functional approach to the assessment and treatment of ADHD. Based on this functional approach, we present a model for classifying performance problems that can be used to guide the selection of appropriate intervention techniques.
