@entity158 catastrophising is an adverse coping mechanism, involving an exaggerated response to anticipated or @entity158 . The purpose of this study was to investigate the influence of @entity158 'catastrophising', as measured using the @entity158 ( @entity158 ), on treatment outcomes after surgery for @entity2649 ( @entity2649 ). A total of 138 @entity1 (47 @entity1 and 91 @entity1 , mean age 65.9; 45 to 78) were assigned to low ( @entity158 score < 25, n = 68) and high ( @entity158 score >=  25, n = 70) @entity158 groups. The primary outcome measure was the @entity717 Index (ODI) 12 months after surgery. Secondary outcome measures included the ODI and @entity227 ( @entity227 ) for back and @entity158 , which were recorded at each assessment conducted during the 12-month follow-up period The overall changes in the ODI and @entity615 over a 12-month period were significantly different between the groups (ODI, p < 0.001; @entity227 for @entity615 , p < 0.001; @entity227 for @entity158 , p = 0.040). The ODI and @entity615 significantly decreased over time after surgery in both groups (p < 0.001 for all three variables). The patterns of change in the ODI and @entity227 for @entity615 during the follow-up period significantly differed between the two groups, suggesting that the @entity158 group is a potential treatment moderator. However, there was no difference in the ODI and @entity615 between the low and high @entity158 groups 12 months after surgery. In terms of minimum clinically important differences in ODI scores (12.8), 22 @entity1 (40.7%) had an unsatisfactory surgical outcome in the low @entity158 group and 16 (32.6%) in the high @entity158 group. There was no statistically significant difference between the two groups (p  = 0.539). Pre-operative catastrophising did not always result in a poor outcome 12 months after surgery, which indicates that this could moderate the efficacy of surgery for @entity2649 .
