SF-36 sum score and subscores in relation to preoperative somatisation measured by the SOMS-2. High somatoform disorder values (squares) were those in the worst 25 percentiles of the cohort (SOMS-2 score 12 as threshold value). Preoperatively and postoperatively the health status of patients with somatoform disorder was worse in most subscales. a Preoperative SF-36 scores in relation to preoperative somatisation. b Postoperative SF-36 scores at 6 weeks in relation to preoperative somatisation
