title: [Psychological factors associated with chronic pain].
abstract: Current knowledge of the complex relationship between chronic pain and its several psychological aspects is reviewed. After a word of caution concerning the selection biases frequently present in the samples described in the literature, the authors examine the relationships between pain and personality, pain and psychopathology and lastly pain and environment (stress). While chronic pain and depression share some neurochemical abnormalities suggesting new lines of research, much remains to be done to improve the clinical characterization of pain and notably its prognostic aspects.
