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 .
A Prospective Study of Work Perceptions and Psychosocial Factors Affecting the Report of Back Injury
A longitudinal , prospect i ve study was conducted on 3,020 aircraft employees to identify risk factors for reporting acute back pain at work . The premorbid data included individual physical , psychosocial , and workplace factors . During slightly more than 4 years of follow-up , 279 subjects reported back problems . Other than a history of current or recent back problems , the factors found to be most predictive of subsequent reports in a multivariate model were work perceptions and certain psychosocial responses identified on the Minnesota Multiphasic Personality Inventory ( MMPI ) . Subjects who stated that they “ hardly ever ” enjoyed their job tasks were 2.5 times more likely to report a back injury ( P = 0.0001 ) than subjects who “ almost always ” enjoyed their job tasks . The quintile of subjects scoring highest on Scale-3 ( Hy ) of the MMPI were 2.0 times more likely to report a back injury ( P = 0.0001 ) than subjects with the lowest scores . The multivariate model , including job task enjoyment , MMPI Scale-3 , and history of back treatment , revealed that subjects in the highest risk group had 3.3 times the number of reports in the lowest risk group . These findings emphasize the importance of adopting a broader approach to the multifaceted problem of back complaints in industry and help explain why past prevention efforts focusing on purely physical factors have been unsuccessful
