title: [Anxiety and depression in patients with chronic pain: neuropathic and nociceptive].
abstract: OBJECTIVE
  To describe and compare anxiety and depression symptoms between two group patients with neuropathic and nociceptive pain those arrive for first time to a clinic of pain.
  
  
  METHODS
  Non-experimental, exploratory and descriptive design. Seventy-eight patients that arrive the first time to a clinic of pain were evaluated; those patients were divided in two groups: neuropathic pain with 44 patients and nociceptive pain with 34 patients. To evaluate anxiety and depression we use the Anxiety and Depression Scale (HAD), this scale is adapted and validated in Mexico.
  
  
  RESULTS
  From the 78 patients in the study, the 76.9% were female and 23.1% were male. The age average was (56.9 +/- 16.8 year-old for neuropathic pain and 63.1 +/- 17.2 year-old for nociceptive pain). The reliability of the scale HAD was evaluated by the Chronbach's alpha analysis with an r = 0.826. There was no significance difference in anxiety and depression between types of pain, but after analyzing all of the patients we found that anxiety was more frequent than depression p < 0.0001.
  
  
  CONCLUSIONS
  Independently of the algological diagnosis, patients presented almost the same affective symptoms.
