The study aimed to investigate the effects of preoperative depression on post-operative pain and disability following discectomy surgery. Psychological health was measured using the PHQ-8 and the Mental Component Score of the SF-12. Disability and pain were collected using the Oswestry Disability Index and Numeric Pain Rating Scales. Data included from 1104 patients (mean[SD]age = 43.90 [13.13]; 52% female sex) in Poisson Regression models showed depression increased the risk of both leg pain and overall poor surgical outcomes (IRR[95% CI]= 1.67[1.14 to 2.50] ; 1.88[1.48 to 2.40]; 1.50[0.99 to 2.29]; 1.67[1.29 to 2.16]; 1.56 1.09 to 2.24] ;1.72[1.40 to 2.10]; 1.61[1.07 to 2.43]; 1.90[ 1.46 to 2.47]; 1.92[1.20 to 3.09];2.08[1.51 to 2.86]; 1.90 [1.21 to 22.61], 1.93[1.55 to 2.40]) . Psychological factors do have influence on recovery following discectomy surgery and should be acknowledged pre-operatively.xi, 84electronicenhttp://purl.org/coar/access_right/c_f1cfmaster thesisHebert, JefferyKinesiology
