初级卫生保健提供者目前使用的评估身体活动的工具没有评估其确定患者是否达到推荐活动水平的能力。本研究的目的是评估自我报告的简短（<30秒）身体活动“生命体征”问卷（PAVS）的身体活动与更简短（3-5分钟）的有效可修改活动问卷（MAQ）的反应的同时有效性。使用百分比和κ系数评估了2014年2家诊所的初级保健患者向PAVS和MAQ报告的活动之间的一致性。协议包括符合或不符合美国卫生与公众服务部2008年美国人有氧体育活动指南（PA指南）。我们使用Pearson相关性和Bland-Altman一致性图，比较了2014年在初级保健诊所向PAVS和MAQ报告的患者自我报告的每周中度至剧烈体力活动的通常分钟数。在269例报告体力活动的知情同意患者中，PAVS结果与MAQ结果在89.6%的时间内一致，并且在识别不符合PA指南建议的患者方面表现出良好的一致性（κ = 0.55，ρ = 0.57; P <0.001）。PAVS报告的每周中度至剧烈体力活动的15分钟与MAQ报告的相同时间呈正相关（r = 0.71; P < .001）。PAVS可能是一个有效的工具，用于确定初级保健患者谁需要咨询有关体力活动。应进一步评估PAVS与患者人群中身体活动的重复客观测量的一致性。
No tool currently used by primary health care providers to assess physical activity has been evaluated for its ability to determine whether or not patients achieve recommended levels of activity. The purpose of this study was to assess concurrent validity of physical activity self-reported to the brief (<30 sec) Physical Activity “Vital Sign” questionnaire (PAVS) compared with responses to the lengthier (3–5 min), validated Modifiable Activity Questionnaire (MAQ). Agreement between activity reported to the PAVS and MAQ by primary care patients at 2 clinics in 2014 was assessed by using percentages and κ coefficients. Agreement consisted of meeting or not meeting the 2008 Aerobic Physical Activity Guidelines for Americans (PA Guidelines) of the US Department of Health and Human Services. We compared self-reported usual minutes per week of moderate-to-vigorous physical activity among patients at a primary care clinic in 2014 who reported to PAVS and to MAQ by using Pearson correlation and Bland–Altman plots of agreement. Among 269 consenting patients who reported physical activity, PAVS results agreed with those of MAQ 89.6% of the time and demonstrated good agreement in identifying patients who did not meet PA Guidelines recommendations (κ = 0.55, ρ = 0.57; P < .001). Usual minutes per week of moderate-to-vigorous physical activity reported to PAVS had a high positive correlation with the same reported to MAQ (r = 0.71; P < .001). PAVS may be a valid tool for identifying primary care patients who need counseling about physical activity. PAVS should be assessed further for agreement with repeated objective measures of physical activity in the patient population.
