Does emotional disclosure about stress improve health in rheumatoid arthritis? Randomized, controlled trials of written and spoken disclosure.

Studies of the effects of disclosing stressful experiences among patients with rheumatoid arthritis (RA) have yielded inconsistent findings, perhaps due to different disclosure methods--writing or speaking--and various methodological limitations. We randomized adults with RA to a writing (n=88) or speaking (to a recorder) sample (n=93), and within each sample, to either disclosure or 1 of 2 control groups (positive or neutral events), which conducted four 20-minute, at-home sessions. Follow-up evaluations at 1, 3, and 6 months included self-reported, behavioral, physiological, and blinded physician-assessed outcomes.

Alexithymia and pain in three chronic pain samples: comparing Caucasians and African Americans.

Objective: African Americans often report greater pain than do Caucasians, but the factors responsible for this discrepancy are not known. We examined whether alexithymia-the trait of difficulty identifying and describing one's feelings and lacking introspection-may contribute to this ethnic group difference. We tested whether the mean level of alexithymia is higher, and whether alexithymia and pain are more highly correlated, among African Americans than among Caucasians in patients with chronic pain disorders.

Changing face of pain: evolution of pain research in psychosomatic medicine.

Objective: This article provides an overview of how psychosomatic research on pain has evolved over the past 60 years as exemplified by studies published in Psychosomatic Medicine.

Methods: Each issue of Psychosomatic Medicine from 1939 to 1999 was reviewed to identify papers that dealt with pain, painful medical conditions, or pain management. A total of 150 papers were identified and grouped into seven categories: 1) case studies; 2) studies of personality traits and other individual differences; 3) psychophysiological studies of pain; 4) studies using pain induction techniques; 5) studies examining the relation of relation of race, ethnicity, and culture to pain; 6) studies of pain unique to women; and 7) studies examining treatments for pain.
