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.
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).
The brief physical activity assessment tool produced repeatable estimates of "sufficient total physical activity", correctly classifying over 76% of cases (kappa 0.53, 95% confidence interval (CI) 0.33 to 0.72). The validity coefficient was reasonable (kappa 0.40, 95% CI 0.12 to 0.69), with good percentage agreement (71%).
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.
评估一种简短的身体活动评估工具的可靠性和有效性，该工具适用于医生在初级保健环境中识别不活跃的患者。
志愿家庭医生（n = 8）使用简短的身体活动评估工具对同意参与的患者（n = 75）进行身体活动参与情况筛查。在一周内评估了评分者间信度（n = 71）。通过客观身体活动监测器（计算机科学与应用加速度计；n = 42）评估效度。
简短的身体活动评估工具对“足够的总体身体活动”产生了可重复的估计，正确分类了超过76%的病例（kappa值为0.53，95%置信区间（CI）为0.33至0.72）。效度系数合理（kappa值为0.40，95%CI为0.12至0.69），一致性百分比良好（71%）。
简短的身体活动评估工具是一种可靠的工具，其效度与更详细的身体活动自我报告测量方法相似。它是一种可在常规初级医疗保健服务中有效使用的工具，用于识别可能需要身体活动建议的身体活动不足的患者。
