"I battle pain every single day": Pain-related illness intrusiveness among persons with multiple sclerosis.

Controlling for level of disease severity, pain-related illness intrusiveness was a significant predictor of MS-related illness intrusiveness (p < .001). Depressive symptom severity was the strongest predictor of pain-related illness intrusiveness (p < .001), followed by pain catastrophizing (p < .001). The relationship between pain-related illness intrusiveness and pain catastrophizing was mediated (med) by coping strategies (Rmed2 = .15) and support from family and friends (Rmed2 = .07), with the latter mediating pain-related illness intrusiveness's relationship with depressive symptom severity (Rmed2 = .10).
