DEPRESSION IN PAINFUL CHRONIC DISORDERS - THE ROLE OF PAIN AND CONFLICT ABOUT PAIN

Chronic pain severity, the responses of the significant other to the patient's pain, and social network relationships were investigated for their contributions to depression among patients with myofascial pain disorders (N = 67) and arthritis (N = 83). Interview data were gathered using the Beck Depression Inventory, McGill Pain Inventory, Multidimensional Pain Inventory, and Interpersonal Relationships Inventory. Patients with myofascial pain disorders reported significantly more severe depression and pain, more conflict about their pain, and more network conflict than those with arthritis. They also reported less network social support After controlling for the type of painful chronic disorder, multiple linear regression analyses indicated that more severe depression was significantly associated with more severe pain, conflict about pain, and less network social support. Conflict about pain may increase the risk of depression for patients with chronic painful disorders. Patients with myofascial pain disorders, however, may experience more conflict about their pain because of the absence of objective physical findings that corroborate the report of pain.
