title: Does pain relief improve pain behavior and mood in chronic pain patients?
abstract: Chronic pain is a subjective experience and has not only physical, but also psychological and social dimensions. In the present study, we sought to determine whether an effective pain reduction would improve mood, behavioral, and cognitive outcome measures in chronic pain patients. Four-hundred-seventy-seven patients entering pain therapy at our university pain center were prospectively studied during the first year of treatment. Patients received pharmacotherapy, acupuncture, transcutaneous nerve stimulation, physiotherapy, and invasive pain treatment. Intensity and quality of pain were assessed with the Visual Analog Scale and Multidimensional Pain Scale. Psychological and social aspects were evaluated using the Pain Behavior Questionnaire and the Profile of Mood States questionnaire. Significant reductions in pain intensity (Visual Analog Scale, 7.35 at pretreatment and 1.03 after 12 mo; P = 0.01; Multidimensional Pain Scale, F = 6.185; P < 0.001) were accompanied by improvements in behavioral and cognitive dimensions (Pain Behavior Questionnaire, F = 9.483; P = 0.002). However, mood and psychological well-being did not improve (Profile of Mood States, F = 0.416; P = 0.551). The authors conclude that reducing pain intensity improves behavioral and cognitive dimensions but not psychological well-being and cognitive assessment.
