The Veterans Specific Activity Questionnaire (VSAQ) has been used to individualize exercise testing (ET) and to indirectly assess cardiorespiratory fitness (CRF) in epidemiological studies. Nevertheless, there is no validated Portuguese version.
To verify the criterion-related validity and the measurement equivalence of a Portuguese version of VSAQ in 95 individuals, 8 women (aged 69 ± 7 years) referred to ET.
The subjects performed a cardiopulmonary test with incremental to maximal exercise on a cycle ergometer. The correlation between VSAQ score and Maximum Measured and Estimated METs was compared to results from other studies. The VSAQ Nomogram was calculated and its results were compared to CRF real values by linear regression. Limits of concordance and mean differences (biases) were assessed according to the Bland Altman methodology.
The VSAQ scores were significantly correlated to the Measured METs (r = 0.64) and Estimated METs (r = 0.67), results that were equivalent to those obtained by the original versions. The VSAQ Nomogram presented multiple R of 0.78 (Measured MET) and 0.80 (Estimated MET). However, the Nomogram seems to have underestimated CRF values greater than 6 METs.
The VSAQ version confirmed its validity and equivalence to the original version, especially when evaluating individuals with coronary heart disease and older adults.
Veterans Specific Activity Questionnaire（VSAQ）已被用于个体化运动测试（ET）和间接评估在流行病学研究中的心肺功能（CRF）。然而，目前还没有经过验证的葡萄牙版本。
验证 VSAQ 葡萄牙语版本在 95 名接受 ET 的个体中的效标关联效度和测量等效性，其中包括 8 名女性（年龄 69 ± 7 岁）。
受试者在自行车测功计上进行递增至最大运动的心肺测试。VSAQ 评分与最大实测和估计 METs 之间的相关性与其他研究的结果进行了比较。计算了 VSAQ 列线图，并通过线性回归将其结果与 CRF 的实际值进行了比较。根据 Bland Altman 方法评估了一致性界限和平均差异（偏差）。
VSAQ 评分与实测 METs（r = 0.64）和估计 METs（r = 0.67）显著相关，结果与原始版本相当。VSAQ 列线图的多重 R 为 0.78（实测 MET）和 0.80（估计 MET）。然而，列线图似乎低估了大于 6 METs 的 CRF 值。
VSAQ 版本证实了其有效性和与原始版本的等效性，特别是在评估冠心病和老年人个体时。
