To evaluate the convergent validity of the PAQ-A for assessing physical activity (PA) in overweight (including obese) adolescents.
Two hundred and three Spanish adolescents (96 females), aged 13-17 years, were selected for this study. Levels of PA were self-reported by 3-day activity diary, activity rating and PAQ-A. Adolescents wore the ActiGraph accelerometer for 7 days. Overweight was classified according to International Obesity Task Force age- and sex-specific body mass index cut offs.
Fifty-four (33 male and 21 female) adolescents (27%) were classified as overweight or obese. The PAQ-A was moderately related in the overweight adolescent group to an activity rating (ρ=0.52), total PA and moderate-to-vigorous PA assessed by activity monitor (ρ=0.52 and 0.43) and total PA and moderate-to-vigorous PA assessed by activity diary (ρ=0.32 and 0.47). There were no significant differences in the correlation coefficients between non-overweight and overweight adolescents.
The PAQ-A shows a reasonable validity for assessing PA in Spanish overweight adolescents.
评估 PAQ-A 评估超重（包括肥胖）青少年身体活动（PA）的聚合效度。
本研究选取了 203 名西班牙青少年（女性 96 名，年龄 13-17 岁）。通过 3 天活动日记、活动等级和 PAQ-A 自我报告 PA 水平。青少年佩戴 ActiGraph 加速度计 7 天。超重根据国际肥胖工作组特定年龄和性别的体重指数切点进行分类。
54 名（男性 33 名，女性 21 名）超重或肥胖的青少年（27%）被分类。PAQ-A 与超重青少年组的活动等级（ρ=0.52）、活动监测器评估的总 PA 和中到剧烈 PA（ρ=0.52 和 0.43）以及活动日记评估的总 PA 和中到剧烈 PA（ρ=0.32 和 0.47）中度相关。非超重和超重青少年的相关系数没有显著差异。
PAQ-A 对评估西班牙超重青少年的 PA 具有合理的有效性。
