Progress in advancing understanding of the role of "catastrophizing" in pain and associated physical and psychosocial disability may be furthered by (1) consideration of the construct of catastrophizing, (2) evaluation of the extent to which currently available measures of pain catastrophizing tap into that construct, (3) investigation of the relation of catastrophizing to personal trait variables (e.g., neuroticism and worry), and (4) identification of the conditions (or states) under which catastrophizing is most likely to occur. In this article, the authors discuss these issues and suggest directions for future research.
