Investigating Post-Exertional Malaise As A Core Symptom Of Myalgic Encephalomyelitis And Chronic Fatigue Syndrome: A Meta-Analytic Approach, Abigail A. Brown
College of Science and Health Theses and Dissertations
Efforts to establish a reliable and valid case definition for myalgic encephalomyelitis and chronic fatigue syndrome (ME and CFS) have been complicated by an over-reliance on clinical consensus, and inconsistent application of established case definitions by researchers across study sites. This has resulted in the absence of an empirically-based case definition for ME and CFS, as well as failed replication studies on potential diagnostic tests and biomarkers. One step toward an empirically-driven case definition is determining which symptoms best discriminate between patients with ME and CFS versus controls. Post-exertional malaise (PEM) is considered a cardinal symptom of ME and CFS …

Cognitive behavioral theories of chronic fatigue syndrome (CFS) assert that cognitions and behaviors perpetuate the fatigue and impairment that individuals with CFS experience (Wessely, Butler, Chalder, & David, 1991). Vercoulen and colleagues (1998) utilized structural equation modeling to empirically develop a cognitive behavioral model of CFS. The resulting model indicated that attributing symptoms to a physical cause, focusing on symptoms, and feeling less control over symptoms were associated with increased fatigue. Additionally, individuals who attributed symptoms to a physical cause reported lower activity levels and more fatigue and impairment. However, in an attempt to replicate this model, Song and Jason …
