The study took place in New Zealand and included 93 preschool boys that were placed in a “hyperactive” group, control group, or in another comparison group where symptoms were present but less severe and, thus, gave the researcher the ability to look at a wide range of ADHD symptoms. According to the author, only boys were included both because of logistics and because they tend to have more observable behaviors linked to ADHD than girls. Eighty-nine fathers participated. Data was collected using parent observations, interviews, and questionnaires, as well as teacher questionnaires. The study spanned three years, starting when the boys were an average of four years-old. A second round of data was collected two and a half years later when the boys were an average age of seven.

Although I wont summarize the full criteria here, I want to talk about four important aspects of the diagnosis of ADHD, some of which are often disregarded by clinicians resulting in questionable diagnoses.
