The self-regulation of fatigue and associated complaints: an exploratory simulation

Abstract

A computer simulation has been developed that re¯ects the microdynamics of dealing with fatigue and associated complaints. The theoretical base was derived from Leventhal, Nerenz and Steele's self-regulation model; the empirical base from a large-scale diary study carried out over a period of 3 weeks. The simulation results demonstrate that the process of self-regulation is non-linear. Consequently, some patient education assumptions are challenged: that individuals suffering from fatigue and associated complaints are likely to follow a similar trajectory, that interventions should not be started until after a 6 weeks delay, and that an intervention always produces the same results. These insights may be generalised to other health complaints that have no medical explanation. #

Cognitive-behavioural therapy v. mirtazapine for chronic fatigue and neurasthenia: randomised placebo-controlled trial

“…This is consistent with the results of a simulation analysis of the self-regulation of fatigue, in which the most effective treatment is stage-dependent with an initial period of delay before active intervention. 29 It is possible that an introductory treatment phase with a cognitive-behavioural approach, focusing on an integrative model of fatigue, emphasising cognitive appraisal and body awareness, and the importance of regular, adjusted physical activity, brings better understanding of and better compliance with pharmacological treatment.…”

The challenge of the past for the future of the social sciences

“…The study shows how spatio-temporal feedback systems can be operationalized and studied in an empirical way with the help of computer simulation of cellular automata. In the domain of psychology (van Mens- Verhulst et al, 2003; demonstrated that a dynamic simulation model was very useful to understand the self-organizing behavior of patients with complaints of fatigue.…”
