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 .
Predicting long-term functional limitations among back pain patients in primary care settings.
To identify predictors of back-related long-term functional limitations , 1213 adult enrollees of a Health Maintenance Organization ( HMO ) in Washington state were interviewed about a month after a consultation for back pain in a primary care setting in 1989 - 1990 , and followed each year thereafter . Out of 100 factors documented at the one-month assessment , measures of somatization , depression , functional limitations , and pain were the strongest predictors of two-year modified Rol and -Morris score among a r and om sub sample of 569 subjects . A multiple regression model containing the Symptom Checklist Depression and Somatization scores , the one-month modified Rol and -Morris score and the number of pain days in the past six months explained about 30 % of the variance in the outcome . Using recursive partitioning , a very simple model was developed to identify patients at high risk of sustaining long-term significant functional limitations . The regression model and the recursive partitioning model were successfully tested in a fresh sample of patients ( n = 644 ) . Clinical application of the recursive partitioning model and method ological aspects of this study are discussed
