为了评估在意大利进行的一项关于消化道癌症的病例对照研究中使用的问卷信息的可比性和重复性，从医院对照的大样本中随机选择了总共400名受试者，并在家里联系了他们重复采访。在这些人中，294人(73%)被重新采访。计算了选定的400名受试者以及第一次和第二次面谈的294名应答者的摄入量平均值。这些数值具有可比性，大多数都在10%的范围内。第一次和第二次访谈的斯皮尔曼相关系数(r(S))为>；糕点、意大利面或大米、面包、鱼、牛奶、绿色蔬菜、鸡蛋和苹果的消费量为0.65；肉类、鸡肉、肝脏、火腿、冷盘、奶酪、水果、卷心菜、胡萝卜、西红柿、辣椒、沙拉、柑橘类水果和甜瓜的消费量低于0.50。对于所有食物，第二次采访的估计平均每周摄入量随着第一次采访的三分之增加而持续和显著增加。这项研究表明，来自家庭访谈的受试者的饮食信息与他们在医院最初访谈时提供的饮食信息具有令人满意的可比性，并且在两种背景下收集的信息具有良好的重复性。
In order to assess the comparability and reproducibility of information from a questionnaire used in a case-control study on digestive tract cancers conducted in Italy, a total of 400 subjects were randomly selected from a large sample of hospital controls and contacted at home to repeat the interview. Of these, 294 (73%) subjects were re-interviewed. Mean values of intake were computed for the 400 subjects selected, and among the 294 responders for the first and second interview. These values were comparable, most of them being within a 10% range. Spearman correlation coefficient (r(s)) values of consumption between the first and second interview were > 0.65 for consumption of pastries, pasta or rice, bread, fish, milk, green vegetables, eggs and apples; between 0.50 and 0.65 for meat, chicken, liver, ham, cold cuts, cheese, fruit, cabbage, carrots, tomatoes, peppers, salad, citrus fruit and melon; and lower than 0.50 for a few infrequently eaten foods. For all foods, the estimated average weekly intake in the second interview increased consistently and substantially with increasing tertile of the first interview. This study shows a satisfactory comparability of dietary information from subjects interviewed at home with that provided during their original interview in the hospital, and a good reproducibility of information collected in the two settings.
