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 .
Use of a subjective health measure on Chinese low back pain patients in Hong Kong.
STUDY DESIGN A prospect i ve observational study on the use of the Aberdeen Low Back Pain Disability Scale . OBJECTIVE To evaluate the reliability , validity , and responsiveness of the Chinese adaptation of the Aberdeen Low Back Pain Scale in Chinese patients in Hong Kong who have back pain . SUMMARY OF BACKGROUND DATA Frontline clinicians , research ers , and health care managers in Hong Kong are urgently in need of a Chinese adaptation of a low back pain outcome measure that has been subjected to a rigorous process of psychometric and clinical testing . METHODS Four sample s with 473 consecutive adult patients with low back pain from six physiotherapy outpatient departments in Hong Kong who completed the Aberdeen Low Back Pain Scale  were observed and measured at time points including the beginning physiotherapy ; 10 days , 3 weeks , and 6 weeks after physiotherapy ; and when discharged from treatment . RESULTS The test-retest reliability coefficient was 0.94 ( 0.94 in the original English version ; figures from the English version are reported in parentheses ) . The Cronbach alpha coefficient was 0.85 ( 0.80 ) . The Spearman correlation coefficient , when the Aberdeen score was correlated with that of a generic current 42-item question naire regarding the patient 's perceived health to establish cross-sectional construct validity , was 0.59 ( 0.36 - 0.66 , with the Short Form 36 scale ) . The effect sizes ( responsiveness ) at weeks 3 and 6 after treatment began were 0.59 and 0.81 , respectively ( a high of 0.62 reported in the English version ) . CONCLUSIONS The Chinese version of the Aberdeen Low Back Pain Disability Scale retained the high levels of reliability , validity , and responsiveness of the original English version when tested in Hong Kong in four sample s of Chinese patients with low back pain
