PURPOSE: To identify questionnaires and scales that measure functioning and
disability in low-back pain (LBP) and determine whether the measurements are
comparable with the International Classification of Functioning, Disability and
Health (ICFDH). METHODS:
We searched MEDLINE, EMBase, CINAHL and PEDro in
English, and CNKI and Wanfang Data in Chinese in a period from the date of the
database establishment to September 2010. From the identified literature,
questionnaires and scales used to assess LBP-related functioning and disability
were collected and classified. Each item in each questionnaire and scale was
extracted and classified according to the ICFDH categories. RESULTS: We have
reviewed 7968 published articles and identified a total of fifteen
questionnaires. A total of 219 items were analyzed and a total of 354 concepts
contained in these items and 345 could be linked to ICFDH components, 138 linked
to body function, 20 to body structure, 174 to activities and participation, and
13 to environmental factors, and 9 to a non-classifiable cluster. In the body
functions component, only the single category "sensation of pain" was covered by
most questionnaires. In the activity and participation component, "changing basic
body position"; "walking" and "maintaining a body position" were covered by most
questionnaires. Analyzing individual questionnaires, we found that two
questionnaires (Clinical Back Pain Questionnaire and Million Disability
Questionnaire) demonstrate a well-balanced distribution of items across different ICFDH components. CONCLUSION: This study may help researchers and clinicians to
choose the most appropriate questionnaires for a specific purpose as well as help
compare studies that have used different questionnaires for low back pain assessment and provide valuable information on the content quality of these
questionnaires for them. Furthermore, based on our results, more comprehensive
and balanced instruments may be developed for more accurate assessment of
functioning in LBP and perhaps other clinical conditions.
