Screening for Physical Activity in Family PracticeEvaluation of Two Brief Assessment Tools
Abstract
Background Physical activity (PA) is relevant to the prevention and management of many health conditions in family practice. There is a need for an efficient, reliable, and valid assessment tool to identify patients in need of PA interventions.Methods Twenty-eight family physicians in three Australian cities assessed the PA of their adult patients during 2004 using either a two- (2Q) or three-question (3Q) assessment. This was administered again approximately 3 days later to evaluate test-retest reliability. Concurrent validity was evaluated by measuring agreement with the Active Australia Questionnaire, and criterion validity by comparison with 7-day Computer Science Applications, Inc. (CSA) accelerometer counts.Results A total of 509 patients participated, with 428 (84%) completing a repeat assessment, and 415 (82%) accelerometer monitoring. The brief assessments had moderate test-retest reliability (2Q k=58.0%, 95% confidence interval [CI]=47.2-68.8%; 3Q k=55.6%, 95% CI=43.8-67.4%); fair to moderate concurrent validity (2Q k=46.7%, 95% CI=35.6-57.9%; 3Q k=38.7%, 95% CI=26.4-51.1%); and poor to fair criterion validity (2Q k=18.2%, 95% CI=3.9-32.6%; 3Q k=24.3%, 95% CI=11.6-36.9%) for identifying patients as sufficiently active. A four-level scale of PA derived from the PA assessments was significantly correlated with accelerometer minutes (2Q rho=0.39, 95% CI=0.28-0.49; 3Q rho=0.31, 95% CI=0.18-0.43). Physicians reported that the assessments took 1 to 2 minutes to complete.Conclusions Both PA assessments were feasible to use in family practice, and were suitable for identifying the least active patients. The 2Q assessment was preferred by clinicians and may be most appropriate for dissemination.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
