^aHigher scores indicate greater pain interference.

^bNegative incongruence scores indicate that the patient is rating patient pain interference 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.
