To validate the short form of the International Physical Activity Questionnaire in the population of Catalonia (Spain).
A convenience sample wore a uniaxial accelerometer (MTI Actigraph, Computer Science and Application's Inc.) for 7 days and completed the questionnaire, translated to Catalan. The sensitivity and specificity of the questionnaire in measuring adherence to physical activity recommendations were also tested.
Valid data were obtained from 55 participants (29 women). The mean age was 40.5 years. Moderate correlations were found for total physical activity (r=0.27; p<0.05) and the time spent in vigorous activity (r=0.38; p<0.01). Sensitivity was 75% and specificity was 75% (κ=0.33).
The short Catalan version of the International Physical Activity Questionnaire had acceptable validity for the measurement of total and vigorous physical activity. This questionnaire can be used to identify adherence to physical activity recommendations in the Catalan population.
验证国际体力活动问卷简版在加泰罗尼亚（西班牙）人群中的有效性。
一个便利样本佩戴单轴加速度计（MTI Actigraph，计算机科学与应用公司）7天，并完成翻译成加泰罗尼亚语的问卷。还测试了该问卷在测量体力活动建议依从性方面的敏感性和特异性。
从55名参与者（29名女性）中获得了有效数据。平均年龄为40.5岁。发现总体力活动（r = 0.27；p < 0.05）和剧烈活动时间（r = 0.38；p < 0.01）之间存在中等程度的相关性。敏感性为75%，特异性为75%（κ = 0.33）。
国际体力活动问卷的加泰罗尼亚语简版在测量总体力活动和剧烈体力活动方面具有可接受的有效性。该问卷可用于确定加泰罗尼亚人群对体力活动建议的依从性。
