The Fennell Phase Inventory (FPI) is an instrument designed to measure phases of the illnesses known as Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The current study explored how the FPI was related to physical and psychological functioning as well as coping style. Based on FPI scores, 111 adults with ME/CFS were placed in one of three groups: crisis, stabilization, or resolution. Results showed that the crisis group demonstrated significantly worse functioning than at least one other group for depression, quality of life, mental functioning, anxiety, and self-efficacy; and utilized less adaptive coping styles. These results indicate that patients with ME/CFS who are in the crisis phase tend to experience more severe psychological and physical symptoms and utilize poorer coping strategies. Those in the resolution phase maintain the most adaptive coping strategies. Implications for these findings are discussed.

    • "Sickness is an adaptive behavioral response that is appropriate to counteract acute bacterial or viral infections or inflammatory trauma and therefore plays a role in the resolution of inflammation and thus recovery. ME/CFS, on the contrary, is an enduring disorder with a relapsing-remitting or chronic course [12,39]. Using international consensus criteria for ME/CFS, most studies report a waxing and waning or progressive pattern of this disease [40-42]. "

    ABSTRACT: It is of importance whether myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a variant of sickness behavior. The latter is induced by acute infections/injury being principally mediated through proinflammatory cytokines. Sickness is a beneficial behavioral response that serves to enhance recovery, conserves energy and plays a role in the resolution of inflammation. There are behavioral/symptomatic similarities (for example, fatigue, malaise, hyperalgesia) and dissimilarities (gastrointestinal symptoms, anorexia and weight loss) between sickness and ME/CFS. While sickness is an adaptive response induced by proinflammatory cytokines, ME/CFS is a chronic, disabling disorder, where the pathophysiology is related to activation of immunoinflammatory and oxidative pathways and autoimmune responses. While sickness behavior is a state of energy conservation, which plays a role in combating pathogens, ME/CFS is a chronic disease underpinned by a state of energy depletion. While sickness is an acute response to infection/injury, the trigger factors in ME/CFS are less well defined and encompass acute and chronic infections, as well as inflammatory or autoimmune diseases. It is concluded that sickness behavior and ME/CFS are two different conditions.

    ABSTRACT: A sample of patients with chronic fatigue syndrome was recruited to assess coping strategies and illness duration. It was hypothesized that adaptive coping strategies would be higher among those with longer illness duration. Those in the longer illness duration group reported higher use of active coping, positive reframing, planning, and acceptance, and lower use of behavioral disengagement than those in the shorter illness duration group. No significant differences were found between the two illness duration groups for physical impairment or symptom severity, but the long duration group revealed a lower percentage of participants who were working than the short duration group. These findings suggest that individuals with longer or shorter duration of the illness have differences in coping styles but not differences in physical impairment or symptom severity.

    ABSTRACT: To review and synthesize findings across qualitative studies on Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS). Articles were systematically reviewed and analyzed within a meta-analytic framework. Analyses included a multi-perspective examination of ME/CFS, as well as a comparative analysis of ME/CFS versus other chronic conditions. Thirty-four qualitative studies on ME/CFS were included. Findings include three substantive thematic areas that focus on: (1) experiences of people with ME/CFS, (2) experiences of physicians, and (3) themes that intersect both of these groups. For patients, illness development influenced identity, reductions in functioning, and coping. Physician-specific themes described lack of awareness about ME/CFS and recommended improvement in educational resources. Intersecting themes expressed issues with diagnosis creating tensions and fueling the stigmatization of ME/CFS. Findings indicate multilayered, context-specific experiences and ways in which both people with ME/CFS, as well as those involved in their lives (e.g., family or the medical community), interpret this illness. Future qualitative studies should recognize the various facets of the ME/CFS experience, the network members of people with ME/CFS, and the sociocultural environment through which the illness is understood. Health care professionals can gain unique insight from patient experiences, allowing for more accurate diagnoses and treatment recommendations.
