本研究旨在验证荷兰儿童（PAQ-C）和青少年（PAQ-A）体育活动问卷。在对原加拿大PAQ-C和PAQ-A进行调整（即翻译/反翻译和专家委员会评估）后，采用项目级（I-CVI）和量表级（S-CVI）内容效度指标对两份paq的内容效度进行评估和计算。对儿童或青少年及其家长填写的196份PAQ-C和95份PAQ-A进行项目间信度和量表间信度评估。项目间信度采用Cronbach’s alpha （α）计算，项目间信度采用观察一致性百分比和加权kappa （κ）检验。在28名肥胖儿童和16名正常体重儿童的亚样本中，通过将PAQ-A与使用最大心肺运动试验评估峰值摄氧量（VO2峰值）的同时测量的身体活动进行比较，来检验PAQ-A的同时有效性。两种PAQs的I-CVI值均在0.67-1.00之间。PAQ-C和PAQ-A的S-CVI分别为0.89和0.90。共有192个PAQ-C和94个PAQ-A由儿童和家长全部完成。PAQ-C的Cronbach’s α为0.777，PAQ-A的Cronbach’s α为0.758。PAQ-C的一致性为59.9 ~ 74.0%，PAQ-A的一致性为51.1 ~ 77.7%，PAQ-C的加权κ范围为0.48 ~ 0.69，PAQ-A的加权κ范围为0.51 ~ 0.68。PAQ-A总分与VO2峰值之间的相关性（经年龄、性别、身高和体重校正）为0.516 （p = 0.001）。两个paq都有很好的内容效度、可接受的项目间信度和中等到良好的评分者间一致性。此外，PAQ-A总分与VO2峰值呈中度正相关。这两个paq都具有可接受的良好的信度和效度，但是，建议进行进一步的效度测试，以提供对这两个paq的更完整的评估。本文的在线版本（doi:10.1186/2049-3258-72-47）包含补充材料，可供授权用户使用。
This study was designed to validate the Dutch Physical Activity Questionnaires for Children (PAQ-C) and Adolescents (PAQ-A). After adjustment of the original Canadian PAQ-C and PAQ-A (i.e. translation/back-translation and evaluation by expert committee), content validity of both PAQs was assessed and calculated using item-level (I-CVI) and scale-level (S-CVI) content validity indexes. Inter-item and inter-rater reliability of 196 PAQ-C and 95 PAQ-A filled in by both children or adolescents and their parent, were evaluated. Inter-item reliability was calculated by Cronbach’s alpha (α) and inter-rater reliability was examined by percent observed agreement and weighted kappa (κ). Concurrent validity of PAQ-A was examined in a subsample of 28 obese and 16 normal-weight children by comparing it with concurrently measured physical activity using a maximal cardiopulmonary exercise test for the assessment of peak oxygen uptake (VO2 peak). For both PAQs, I-CVI ranged 0.67-1.00. S-CVI was 0.89 for PAQ-C and 0.90 for PAQ-A. A total of 192 PAQ-C and 94 PAQ-A were fully completed by both child and parent. Cronbach’s α was 0.777 for PAQ-C and 0.758 for PAQ-A. Percent agreement ranged 59.9-74.0% for PAQ-C and 51.1-77.7% for PAQ-A, and weighted κ ranged 0.48-0.69 for PAQ-C and 0.51-0.68 for PAQ-A. The correlation between total PAQ-A score and VO2 peak – corrected for age, gender, height and weight – was 0.516 (p = 0.001). Both PAQs have an excellent content validity, an acceptable inter-item reliability and a moderate to good strength of inter-rater agreement. In addition, total PAQ-A score showed a moderate positive correlation with VO2 peak. Both PAQs have an acceptable to good reliability and validity, however, further validity testing is recommended to provide a more complete assessment of both PAQs.
