Pain Sensitivity in Patients with Major Depression: Differential Effect of Pain Sensitivity Measures, Somatic Cofactors, and Disease Characteristics

Abstract

Patients with depression often report pain. Evidence regarding altered pain sensitivity in depressed patients remains, however, inconclusive. In a large cross-sectional study we investigated the association between depression and pain sensitivity with regard to 2 different dimensions of pain sensitivity, as well as the effect of somatic cofactors, symptom severity, and subtype of depression. In 735 patients with a current episode of major depression and 456 never-depressed control participants pain thresholds (pressure pain thresholds, PPTs) were measured at the index finger pad and self-rated suprathreshold pain intensity ratings were obtained using the Pain Sensitivity Questionnaire (PSQ)-..
