We examined the reliability and validity of the Brief Physical Activity Assessment Tool (BPAAT) when administered by telephone interview compared to in-person administration. We analyzed data from the Epi-asthma study. Adult participants registered in the participating Portuguese primary health care centres (PCC) completed the BPAAT via telephone. After ~3 days (range 0-5 days), they had a face-to-face visit at their PCC and completed BPAAT using a tablet. The BPAAT classify individuals as "insufficiently active" (score 0-3) or "sufficiently active" (score 4-8). 355 subjects (60.8% female, 54[IQR 42-66] years) were included. The median BPAAT score was 2[0-4] for both methods, with a significant correlation (rho = 0.58, p<0.001). Test-retest reliability was moderate (ICC = 0.56, 95%CI 0.49-0.63). Agreement in physical activity classification was fair (71.5%, kappa = 0.31, 95%CI 0.21-0.41), with telephone administration classifying more individuals as "sufficiently active" (37.2%) than in-person (15.5%). Telephone administration of the BPAAT is a valid and reliable approach for monitoring of physical activity in the general population. However, it may slightly overestimate activity levels compared to face-to-face administration, particularly among subjects aged 65 years and older.
我们研究了通过电话访谈方式与亲自进行管理相比，简短身体活动评估工具（BPAAT）的可靠性和有效性。我们分析了哮喘流行病学研究的数据。在参与研究的葡萄牙初级卫生保健中心（PCC）登记的成年参与者通过电话完成了BPAAT。约3天后（范围为0 - 5天），他们在其PCC进行了面对面访问，并使用平板电脑完成了BPAAT。BPAAT将个体分类为“活动不足”（得分0 - 3）或“活动充足”（得分4 - 8）。纳入了355名受试者（60.8%为女性，年龄54[四分位间距42 - 66]岁）。两种方法的BPAAT得分中位数均为2[0 - 4]，具有显著相关性（rho = 0.58，p<0.001）。重测信度为中等（ICC = 0.56，95%CI 0.49 - 0.63）。身体活动分类的一致性为中等（71.5%，kappa = 0.31，95%CI 0.21 - 0.41），电话管理将更多个体分类为“活动充足”（37.2%），高于面对面管理（15.5%）。通过电话管理BPAAT是监测一般人群身体活动的一种有效且可靠的方法。然而，与面对面管理相比，它可能会略微高估活动水平，尤其是在65岁及以上的受试者中。
