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 .
Assessing Health‐Related Quality of Life in Patients With Sciatica
Study Design This study analyzed health-related quality -of-life measures and other clinical and question naire data obtained from the Maine Lumbar Spine Study , a prospect i ve cohort study of persons with low back problems . Objective For persons with sciatica , back pain-specific and general measures of health-related quality -of-life were compared with regard to internal consistency , construct validity , reproducibility , and responsiveness in detecting small changes over a 3-month period . Summary of Background Data Data were collected from 427 participants with sciatica . Baseline in-person interviews were conducted with surgical and medical patients before treatment and by mail at 3 months . Methods  Health-related quality -of-life measures included symptoms ( frequency and bothersomeness of pain and sciatica  ) functional status and well-being ( modified back pain-specific Rol and scale and Medical Outcomes Study 36-item Short Form Health Survey ( SF-36 ) , and disability ( bed rest , work loss , and restricted activity days ) . Results Internal consistency of measures was high . Reproducibility was moderate , as expected after a 3-month interval . The SF-36 bodily pain item and the modified Rol and measure demonstrated the greatest amount of change and were the most highly associated with self-rated improvement . The specific and generic measures changed in the expected direction , except for general health perceptions , which declined slightly . A high correlation between clinical findings or symptoms and the modified Rol and measure , SF-36 , and disability days indicated a high degree of construct validity . Conclusions These measures performed well in measuring the health-related quality -of-life of patients with sciatica . The modified Rol and and the physical dimension of the SF-36 were the measures most responsive to change over time , suggesting their use in prospect i ve evaluation . Disability day measures , although valuable for assessing the societal impact of dysfunction , were less responsive to changes over this short-term follow-up of 3 months
