### Associations among the Fear of Movement, Fatigue, Self-Efficacy, and the Impact of Fibromyalgia  
As shown in Table 4, the fear of movement and most of the dimensions of fatigue (general fatigue, physical fatigue, mental fatigue, reduced activity, and reduced motivation) are directly related to the overall impact of fibromyalgia, the severity of the symptoms,

In this way, the only non-significant correlation was between mental fatigue and the overall fibromyalgiaalgia impact (\(p=0.203\)). In addition, the fear of movement is directly correlated with all fatigue dimensions.  
Self-efficacy, composed of the three dimensions (for coping with symptoms, for physical function, and for pain management) showed more heterogenous results. Only self-efficacy for pain management was observed to have a negative correlation with all fatigue dimensions and with the fear of movement. On the other hand, self-efficacy for coping with symptoms and for physical function negatively correlated with all the variables, except with general fatigue in the case of self-efficacy for coping with symptoms (\(p=0.055\)) and with mental fatigue (\(p=0.879\)) and motivation reduction (\(p=0.071\)), in the case of the self-efficacy for physical function.
