这项横断面研究测试的信度和效度块儿童问卷，以评估在过去7天的饮食。在7天的时间内，10至17岁的儿童和青少年通过电话完成了两次24小时的饮食回忆，然后在周末进行了街区儿童问卷调查。重测信度进行了评估，使用组内相关性的18名参与者谁完成了第二块儿童问卷1个月后。使用配对t检验和Pearson相关系数（针对衰减和能量摄入进行调整），对整个样本和年龄组进行了24小时饮食回忆与街区儿童问卷的有效性评估。参与者为83名儿童和青少年（57%为西班牙裔，21%为非洲裔美国人，23%为白色; 53%为女性受试者，平均年龄13岁）。与24小时饮食回忆相比，Block Kids问卷中碳水化合物能量百分比、水果、100%果汁和蔬菜的平均每日消耗值较高，而所有其他类别的平均每日消耗值较低。除蛋白质和水果/蔬菜的能量百分比外，所有可靠性组内相关性均>0.30。对于大多数营养素/食物组，两种膳食评估方法之间的平均值存在显著差异。调整后的相关系数从碳水化合物能量百分比的0.69到谷类食物的-0.03不等，其中60%的食物组12岁的人比12岁的人高
This cross-sectional study tested the reliability and validity of the Block Kids Questionnaire to assess diet during the past 7 days. Within a 7-day period, 10- to 17-year-old children and adolescents completed two 24-hour dietary recalls by telephone, followed by the Block Kids Questionnaire at the end of the week. Test-retest reliability was assessed using intraclass correlations for 18 participants who completed a second Block Kids Questionnaire 1 month later. Validity of the Block Kids Questionnaire compared to the 24-hour dietary recall was assessed for the whole sample and by age group using paired t tests and Pearson correlation coefficients adjusted for attenuation and energy intake. Participants were 83 children and adolescents (57% Hispanic, 21% African-American, and 23% white; 53% were female subjects, mean age 13 years). The Block Kids Questionnaire mean daily consumption values were higher for percent energy from carbohydrate, and servings of fruit, 100% fruit juice, and vegetables, and lower for all other categories compared to the 24-hour dietary recall. All reliability intraclass correlations were >0.30, except percent energy from protein and fruit/vegetable servings. Significant differences in the means between the two dietary assessment methods were noted for most nutrients/food groups. The adjusted correlation coefficients ranged from 0.69 for percent energy from carbohydrate to -0.03 for grain servings, with 60% of the food group servings 12 years were higher than those aged
