Anxiety and surgical recovery. Reinterpreting the literature
1University of Southampton, Southampton, UK. marcus.munafo@dphpc.ox.ac.uk
Objective:
To critically evaluate the interpretation of the findings reported in the peer-reviewed literature concerning the association of state and trait anxiety with surgical recovery and response to surgery.
Methods:
The Social Science Citation Index (SSCI), Science Citation Index (SCI), Medline and Psychological Abstracts (PsycInfo) databases were searched for studies published since 1981. Reference lists from previous reviews were also searched for additional references. Studies that were not in the public domain were not searched for.
Results:
Twenty-seven studies were identified by the search strategy, met the inclusion criteria and contributed to the review.
Conclusions:
Associations between preoperative measures of anxiety and postoperative mood and pain have been consistently reported. Associations with regard to other recovery variables are less consistent. The existing evidence does not rule out an interpretation of the results as reflecting consistent self-reporting bias rather than causal association.
