Abstract

BACKGROUND

Questionnaires are feasible instruments to assess physical activity (PA) in large samples. The aim of the current study was to evaluate the reliability and validity of the PAQ-A questionnaire in Spanish adolescents using the measurement of PA by accelerometer as criterion.

METHODS

In a sample of 82 adolescents, aged 12 to 17 years, 1-week PAQ-A test-retest was administered. Reliability was analyzed by the Intraclass Correlation Coefficient (ICC) and the internal consistency by the Cronbach's alpha Coefficient. Two hundred thirty-two adolescents, aged 13-17 years, completed the PAQ-A and wore the ActiGraph GT1M accelerometer during 7-days. The PAQ-A was compared against total PA and moderate to vigorous PA (MVPA) obtained by the accelerometer.

RESULTS

Test-retest reliability showed ICC = 0.71 for the final score of PAQ-A. Internal consistency was alpha = 0.65 in the first self-report, alpha = 0.67 in the retest in 82 adolescents sample, and alpha = 0.74 in the 232 adolescents sample. The PAQ-A was moderately correlated with total PA (rho = 0.39) and MVPA (rho= 0.34) assessed by the accelerometer. The PAQ-A obtained significantly moderate correlations in boys but not in girls against the accelerometer.

CONCLUSIONS

The PAQ-A questionnaire shows an adequate reliability and a reasonable validity for assessing PA in Spanish adolescents.

摘要

背景

问卷调查是评估大样本中身体活动（PA）的可行工具。本研究的目的是使用加速度计测量PA作为标准，评估PAQ - A问卷在西班牙青少年中的信度和效度。

方法

在82名年龄在12至17岁的青少年样本中，进行了为期1周的PAQ - A重测。通过组内相关系数（ICC）分析信度，通过克朗巴哈α系数分析内部一致性。232名年龄在13 - 17岁的青少年完成了PAQ - A问卷，并在7天内佩戴了ActiGraph GT1M加速度计。将PAQ - A与加速度计测得的总PA和中度至剧烈PA（MVPA）进行比较。

结果

重测信度显示，PAQ - A最终得分的ICC = 0.71。在82名青少年样本中，首次自我报告的内部一致性α = 0.65，重测时α = 0.67，在232名青少年样本中α = 0.74。PAQ - A与加速度计测得的总PA（rho = 0.39）和MVPA（rho = 0.34）呈中度相关。PAQ - A与加速度计相比，在男孩中获得了显著的中度相关性，而在女孩中则没有。
