^aHigher scores indicate less fatigue.

^bPositive incongruence scores indicate that the patient is rating patient fatigue as higher than the spouse. Models presented did not differ when duration of disease or spouse’s health (measured by the physical component scale of the SF-36) were included. PT – patient; SP – spouse.

^*p < .05;

^**p < .01;

^***p < .001.
