A Multidimensional Model of Fatigue in Patients with Rheumatoid Arthritis

Abstract: Objective To evaluate a multidimensional model testing disease activity, mood disturbance, and poor sleep quality as determinants of fatigue in patients with rheumatoid arthritis (RA). Method The data of 106 participants were drawn from baseline of a randomized comparative efficacy trial of psychosocial interventions for RA. Sets of reliable and valid measures were used to represent model constructs. Structural equation modeling was used to test the direct effects of disease activity, mood disturbance, and p… Show more

“…Fatigue is highly frequent in patients with RA, with the frequency of severe fatigue ranging from 42% to 69% (25). The study by Nicassio et al suggested that a model of increased disease activity, low mood, and poor sleep explains 62% of variance in RA fatigue (26). Deteriorated sleep quality, another frequent symptom of RA, is observed in more than half of patients (25,27).…”

Ni les straté gies de coping ni les attributions causales ne sont apparues être lié es à l'activité clinique de la PR ou à la fatigue des patients.…”
