Most of the outcome question naires had a mixed content reflecting various constructs such as pain and symptoms , sleep disturbances , psychological dysfunctions , physical impairments , and social functions .
STUDY DESIGN A systematic literature review of outcome question naires design ed for assessing functional status or disability in patients with low back pain .
OBJECTIVES To provide a comprehensive overview of all functioning/disability question naires used in recent years and to explore how the main concept(s ) was described or defined in the original paper , the content or the domains of disability , and the measurement properties of the question naires .
SUMMARY OF BACKGROUND DATA A number of clinical tools design ed for evaluating the functional status of patients with low back pain have been developed .
Only a few have been review ed earlier , and there has been little focus on the content reflected in the question naires .
Low Back Pain Rating scale: validation of a tool for assessment of low back pain
Low Back Pain Rating scale is an index scale which includes measurements of pain intensity , disability , and physical impairment . The scale was design ed to monitor the outcome of clinical trials of low back pain treatment . It has been vali date d in 58 patients following first-time discectomy .  The scale rating can be rapidly carried out and requires no special aids . With slight modification it can be used in office and telephone interviews , as well as postal question naires . These modifications only slightly reduce the quantity of information gathered . In the study , a high rater agreement ( 97.7 % ) was found without level difference between two observers using the scale . The validation process included : construct validity , criterion-related validity and item bias , relative to Global Assessment s pronounced by the patient and an experienced clinician . Low Back Pain Rating scale hs been shown to be valid and reliable in the assessment of low back pain
