Also @Winterhail - in response to the article you shared, let’s look at another view of this - (and let’s remember that, even if he had been quoted in context, he was merely giving his opinion, backed up by nothing solid at all):
In 2012, Kagan sparked controversy regarding his views on the field of psychology, and specifically how ADHD diagnoses were being applied. Following the publication of his book Psychology's Ghosts: The Crisis in the Profession and the Way Back — which is primarily a criticism of current psychology practices — Kagan was interviewed by the German magazine Der Spiegel. In the interview, he expresses his concern that doctors and other mental health practitioners are over-diagnosing conditions like ADHD. According to Kagan, this is partly due to the financial incentive psychiatrists, the pharmaceutical industry, and researchers have to diagnose children with a mental illness and prescribe them medication.
The most controversial quotes from his interview come when he describes ADHD as “an invention” and attributes the high number of ADHD diagnoses to “fuzzy diagnostic practices.” He goes on to address several other issues he has with the profession, including the way anxiety and depression diagnoses are provided.
His remarks, specifically those about ADHD, created a stir within the psychological community and prompted many to respond by citing research and studies that have led to a consensus in the profession that the disorder is a legitimate diagnosis. He does not expand on his comments much, though; and this is one of the only places he’s publicly discussed his thoughts on ADHD. So, it’s entirely possible that these comments were abbreviated, taken out of context, or not completely representative of his feelings on the subject.
While Kagan has influenced much of our current understanding regarding child development, his comments do not represent the field of psychology — and they run counter to the consensus of the psychology community that ADHD is a legitimate diagnosis.
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that greatly affects an individual’s ability to function. It can impact a child’s education, social life, and even physical health, and it will often remain a concern into adulthood. Common symptoms of ADHD in adults include trouble staying organized, lack of focus, time blindness, and problems dealing with stress.
