Leonard A. Jason, PhD, is a professor of psychology at DePaul University in Chicago, Illinois, USA and Director of the Center for Community Research at DePaul University which includes the Depaul University Chronic Fatigue Syndrome Project.

Dr. Jason developed chronic fatigue syndrome after contracting infectious mononucleosis in 1989, necessitating a leave of absence from his university job for a year and a half. After recovering enough to return to work, he began studying chronic fatigue syndrome: “What I found was that the illness had a lousy name, chronic fatigue syndrome,” he recalled. “It had an even worse case definition. The tests used to assess people’s psychological conditions were inappropriate. The treatments being used were inappropriate. And the prevalence data was not very good. So I said to myself, ‘Boy, I’m gonna have business for the next 20 years.’”[1] He has become one of the most respected and prolific researchers of chronic fatigue syndrome.

In 2008, David Tuller profiled for The New York Times Dr. Jason's experience as both living with and researching myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).[2]

Chronic Fatigue Syndrome Advisory Committee[edit]

Dr. Jason served as a voting member of the Chronic Fatigue Syndrome Advisory Committee for the U.S. Department of Health and Human Services from April 1, 2004 to April 1, 2011.[10]

Open letter to The Lancet[edit]

Two open letters to the editor of The Lancet urged the editor to commission a fully independent review of the PACE trial, which the journal had published in 2011. The first, written in 2015, was sign by Dr. Jason and 5 of his colleagues. In 2016, thirty-six additional colleagues in the ME/CFS field, signed the second letter.

Pediatric case definition[edit]

Dr. Jason is one of the authors of the Pediatric Case Definition for Myalgic Encephalomyelitis and Chronic Fatigue Syndrome:

  • 2006, "A Pediatric Case Definition for Myalgic Encephalomyelitis and Chronic Fatigue Syndrome"
    "Summary: For a diagnosis of chronic fatigue syndrome (CFS), most researchers use criteria that were developed by Fukuda et al. (1994), with modifications suggested by Reeves et al. (2003). However, this case definition was established for adults rather than children. A Canadian Case Definition (ME/CFS; Myalgic Encephalomyelitis/CFS) has recently been developed, with more specific inclusion criteria (Carruthers et al., 2003). Again, the primary aim of this case definition is to diagnose adult CFS. A significant problem in the literature is the lack of both a pediatric definition of ME/CFS and a reliable instrument to assess it. These deficiencies can lead to criterion variance problems resulting in studies labeling children with a wide variety of symptoms as having ME/CFS. Subsequently, comparisons between articles become more difficult, decreasing the possibility of conducting a meta-analysis. This article presents recommendations developed by the International Association of Chronic Fatigue Syndrome Pediatric Case Definition Working group for a ME/CFS pediatric case definition. It is hoped that this pediatric case definition will lead to more appropriate identification of children and adolescents with ME/CFS."[13]
