Reliability and validity of a brief physical activity-assessment for use by family doctors.
Marshall, Alison L., Smith, Ben J., & Bauman, Adrian (2005) Reliability and validity of a brief physical activity-assessment for use by family doctors. British Journal of Sports Medicine, 39, pp. 294-297.
Objective: To evaluate the reliability and validity of a brief physical activity assessment tool suitable for
doctors to use to identify inactive patients in the primary care setting.
Methods: Volunteer family doctors (n = 8) screened consenting patients (n = 75) for physical activity
participation using a brief physical activity assessment tool. Inter-rater reliability was assessed within one
week (n = 71). Validity was assessed against an objective physical activity monitor (computer science and
applications accelerometer; n = 42).
Results: The brief physical activity assessment tool produced repeatable estimates of ‘‘sufficient total
physical activity’’, correctly classifying over 76% of cases (k 0.53, 95% confidence interval (CI) 0.33 to
0.72). The validity coefficient was reasonable (k 0.40, 95% CI 0.12 to 0.69), with good percentage
Conclusions: The brief physical activity assessment tool is a reliable instrument, with validity similar to that
of more detailed self report measures of physical activity. It is a tool that can be used efficiently in routine
primary healthcare services to identify insufficiently active patients who may need physical activity advice.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
