When a patient's predominant complaint is of physical pain that is not intentionally produced or faked (Factitious Disorder or Malingering) and "psychological factors are judged to have played a significant role in the onset, severity, exacerbation, or maintenance of the pain," this Somatoform Disorder can be diagnosed. Subtyping is based upon the categories of factors thought to predominate:
- Pain Disorder associated with psychological factors
- Pain Disorder associated with both psychological factors and a general medical condition
- Pain Disorder associated with a general medical condition (only): Psychological factors, if present, are judged to play no more than a minimal role. This is not considered a mental disorder so it is coded on Axis III with general medical conditions.
