Efectos de la fatiga anticipatoria y la sintomatología emocional en la percepción de fatiga física y cognitiva

Abstract

<p><em>Objectives: </em>To analyze the effects of anticipatory fatigue and emotional symptomatology on the physical and cognitive perception of fatigue.<em> </em>The conditional and partial effects of independent variables were analyzed by multivariate and univariate analyses in an ex- post-fact and correlational method.<em> </em>Sample was composed of 317 participants (29% come from clinical population). Anticipatory fatigue, and perception of fatigue (by the Chalder et al.´s Fatigue Scale) were measured. Emotional symptoms were assessed by Goldberg´s questionnaire, GHQ-28.<em> </em>Anticipatory fatigue and emotional symptoms (mainly depressive symptoms) had significant effects on the cognitive and physical fatigue. The anticipatory fatigue moderated the effects between group (clinical versus general) and cognitive fatigue.<em> </em>Emotional symptoms (mainly depressive symptoms) and anticipatory fatigue made an important contribution to the cognitive and physical fatigue. However, the contribution of the anticipatory fatigue was no longer significant when the emotional symptoms were considered. It suggests the mediational role of the symptoms between anticipatory fatigue and perception of fatigue.</p>
