title: Stress-related clinical pain and mood in women with chronic pain: moderating effects of depression and positive mood induction.
abstract: BACKGROUND
  Chronic pain with comorbid depression is characterized by poor mood regulation and stress-related pain.
  
  
  OBJECTIVE
  This study aims to compare depressed and non-depressed pain patients in mood and pain stress reactivity and recovery, and test whether a post-stress positive mood induction moderates pain recovery.
  
  
  METHODS
  Women with fibromyalgia and/or osteoarthritis (N = 110) underwent interpersonal stress and were then randomly assigned by pain condition and depression status, assessed via the Center for Epidemiological Studies-Depression scale, to positive versus neutral mood induction.
  
  
  RESULTS
  Depression did not predict stress-related reactivity in despondency, joviality, or clinical pain. However, depression × mood condition predicted recovery in joviality and clinical pain; depressed women recovered only in the positive mood condition, whereas non-depressed women recovered in both mood conditions.
  
  
  CONCLUSIONS
  Depression does not alter pain and mood stress reactivity, but does impair recovery. Boosting post-stress jovial mood ameliorates pain recovery deficits in depressed patients, a finding relevant to chronic pain interventions.
