Four important domains directly related to low back pain are: pain intensity, low-back-pain-specific disability, patient satisfaction with treatment outcome, and work disability. Within each of the domains, different questionnaires have been proposed. This chapter focuses on validated and widely used questionnaires. ⋯ For global perceived effect, we argue that the MCIC is most appropriately defined in terms of at least 'much improved' or 'very satisfied', instead of including 'slightly improved'. Finally, we argue that, from the point of view of cost effectiveness, every day of earlier return to work is important. The exact value for the MCIC can be determined, taking into account the aim of the measurement, the initial scores, the target population and the method used to assess MCIC.

Comparative Study
Predictive validity of the Chronic Pain Coping Inventory in subacute low back pain.
The Chronic Pain Coping Inventory (CPCI) was developed to assess eight behavioral coping strategies hypothesized to be important for pain adaptation. But the predictive validity of the CPCI has yet to be tested in a longitudinal study. Here, 321 workers on sick leave after a work accident affecting the low back pain (LBP) region completed the CPCI during the subacute stage (T1) of LBP as well as the Catastrophizing scale of the Coping Strategies Questionnaire (CSQ). ⋯ Catastrophizing and Guarding were the most strongly associated with depressive mood at T1 but at T2, only depressive mood at T1 predicted this same variable. Results indicated also that the Guarding and Catastrophizing scales were able to predict future work status. The present study clearly reveals the usefulness of Guarding from the CPCI and Catastrophizing from the CSQ, when predicting different outcomes of adjustment to low back pain.

The transition from acute to subacute and chronic low back pain: a study based on determinants of quality of life and prediction of chronic disability.
Follow-up study. ⋯ LBP influences disability and quality of life more than RP. Disability is predicted by pain duration and quality of life is predicted by disability, but pain severity predicts neither one of them. Changes related to determinants of disability and quality of life, and to the prediction of chronic disability, appear 14 days after the onset of pain, supporting that cutoff point for considering a patient as being subacute.

Clinical Trial
Diagnosis of sacroiliac joint pain: validity of individual provocation tests and composites of tests.
Previous research indicates that physical examination cannot diagnose sacroiliac joint (SIJ) pathology. Earlier studies have not reported sensitivities and specificities of composites of provocation tests known to have acceptable inter-examiner reliability. This study examined the diagnostic power of pain provocation SIJ tests singly and in various combinations, in relation to an accepted criterion standard. ⋯ In conclusion, composites of provocation SIJ tests are of value in clinical diagnosis of symptomatic SIJ. Three or more out of six tests or any two of four selected tests have the best predictive power in relation to results of intra-articular anaesthetic block injections. When all six provocation tests do not provoke familiar pain, the SIJ can be ruled out as a source of current LBP.

Responsiveness of the Roland-Morris Disability Questionnaire: consequences of using different external criteria.
To determine the consequences of using different external criteria on responsiveness of the Roland-Morris Disability Questionnaire (RMDQ) in patients with chronic low back pain. ⋯ All pooled effect sizes were well above 0.80, and all other statistics were high, indicating good responsiveness of the RMDQ. However, considerable differences were found in responsiveness, when using different external criteria in a same study population. Therefore, it can be concluded that the magnitude of the responsiveness statistic depends on the used external criteria.
