Several factors were found to be associated with disability at follow-up for at least two different pain symptoms .
However , owing to insufficient studies , no generic risk factors for sick leave were identified .
Conclusions Multiple site pain , high pain severity , older age , baseline disability and longer pain duration were identified as potential prognostic factors for disability across pain sites .
There was limited evidence that anxiety and depression were associated with disability in patients with subacute pain , indicating that these factors may not play as large a role as expected in developing disability due to a pain condition .
Objective This systematic review aims to identify generic prognostic factors for disability and sick leave in subacute pain patients .
Do psychological factors predict outcome in both low-back pain and shoulder pain?
Background and Objective : Psychological factors are assumed to predict persistent or recurrent musculoskeletal pain . The influence of psychological factors in patients with low-back pain ( LBP ) or shoulder pain was explored to study whether there is similarity regarding the factors that predict persisting pain and disability . Methods : Patients presenting in primary care with a new episode of shoulder pain or non-specific (sub)acute low back pain ( LBP ) were enrolled in a prospect i ve study . In both patient groups ,  pain catastrophising , distress , somatisation and fear-avoidance beliefs  were measured at baseline . Primary outcome measures at 3 months were ( 1 ) persistent symptoms , and ( 2 ) < 30 % reduction in functional disability .  Multivariate logistic regression analysis was used to study the associations between psychological factors and outcome . Results : A total of 587 patients with shoulder pain and 171 patients with LBP were enrolled in the study . In patients with shoulder pain , most associations of psychological factors with outcome were weak and not significant . Only in patients with longer symptom duration at baseline ( ⩾3 months ) were higher scores on catastrophising significantly associated with persistent symptoms ( p = 0.04 ) . In patients with LBP , psychological factors were more strongly associated with poor outcome , although most associations were not significant . Conclusion : Psychological factors , with the exception of fear-avoidance beliefs , are more strongly associated with persistent pain and disability in patients with LBP than in those with shoulder pain . This seems to indicate that in a primary care population the influence of psychological factors on outcome may vary across patients with different types of pain
