The role of neuroticism, perfectionism and depression in chronic fatigue syndrome. A structural equation modeling approach

The model considering depression severity as mediator factor between Neuroticism and fatigue severity is the only one of the explored models where all the structural modeling indexes have fitted satisfactorily (Chi square = 27.01, p = 0.079; RMSE = 0.047, CFI = 0.994; SRMR = 0.033). Neuroticism is associated with CFS by the mediation effect of depression severity. This personality variable constitutes a more consistent factor than maladaptive perfectionism in the conceptualization of CFS severity.
