Personality disorders in consorts of patients with chronic pain

Good data on this topic are very scarce. It could be of interest to prepare a systematic review, and then study the topic with a large epidemiological investigation. Of course, it depends on many different factors, including support of specific national health care system, but there must be some common factors that would become evident only with a large study.

Dear Thibaut Deveraux, with Giustino Varrassi we conducted an epidemiological study in Italy on chronic pain, and we partially investigated the role of having a partner. Not association on reduction/impact of severe chronic pain was found. Of course the study was not primarly aimed on this topic. I also think that a good systematic review and/or metanalysis should be performed!
