Manipulations and Spins in Attention Disorders Research: The Case of ADHD and COVID-19

This article raises awareness to manipulations and “spins” that occur in Attention Deficit/Hyperactivity Disorder (ADHD) research. An in-depth inspection was conducted on a high-profile study that suggested that ADHD is a risk factor for infection with COVID-19 and that stimulants reduce that risk (Merzon et al., 2020b). Two additional studies by the same first author were inspected as well, one that was published in the same journal and one that relied on the same dataset. Seven manipulations and spins were identified, including inappropriate operational definitions, misrepresentations, and omissions that produced bogus results and might have concealed potential adverse effects of medications. These distortions illustrate how biased science can contribute to the ethically problematic phenomena of overdiagnosis and overmedication.
