Network model reflecting factors that are associated with fatigue

Relations between all factors of this biopsychosocial model are assumed to be dynamic and reciprocal, with mutually influencing pathways similar to a hanging mobile toy, in which movement of one factor causes changes in all other factors. Another assumption is that individuals differ in terms of the factors involved in fatigue as well as the importance of both the weight of these factors and the strength of the relationships between these factors.
