Pre-surgery emotional distress has had variable associations with outcomes of surgery in past narrative reviews. This meta-analysis was designed to evaluate overall strengths of relation between pre-surgical emotional distress and key post-surgical pain outcomes (i.e., pain intensity, analgesic use, functional impairment) and to identify moderators that might explain effect size heterogeneity between studies. PubMed, Web of Science, PsychINFO, Google Scholar, and Science Direct databases were searched to identify studies subjected to meta-analysis.
