水果和蔬菜的消费可以降低慢性疾病和肥胖的风险。儿童的水果和蔬菜摄入量是通过偏好或愿意尝试它们来调节的。本研究的主要目的是适应以前验证的WillTry工具，并评估适应版本中的儿童在Guam.MethodsAdaptations的WillTry工具包括新的水果和蔬菜独特的关岛和常见的。2013年参加了2个社区夏令营的3至11岁儿童在初次访谈和3至72小时后进行的第二次访谈中被展示了与14个食物问题相匹配的图像。回答为“否”、“可能”或“是”，分别编码为1、2或3。分数越高，表明越愿意尝试水果和蔬菜。因素分析确定了意愿的组成部分。心理测量特性和可靠性进行了analysed.Results65名儿童完成了第一次面试，64完成了第二次。因子分析显示了3个分量（量表）：1）当地新（番石榴，面包果，茄子，甜肥皂，星星苹果，芋头叶），2）当地常见（胡萝卜，木瓜，长豆，沙拉蔬菜），和3）进口（苹果，罐头桃，罐头玉米）。除引进量表外，其余量表均具有足够的内部一致性（Cronbach’s alpha > 0.69）。各量表均具有较好的信度（ICC > 0.76）。我们没有发现任何规模的年龄，性别或营地类型的显着差异。平均得分为2.1（当地小说），2.4（当地常见），和2.7（进口），都有显着different.ConclusionThe适应WillTry的文化相关，并具有类似的心理测量特性的原始。一个意想不到的发现是该工具记录营养转变的潜力。
IntroductionFruit and vegetable consumption may reduce risk for chronic disease and obesity. Children's fruit and vegetable intake is mediated by a preference or willingness to try them. This study's primary objective was to adapt the previously validated WillTry tool and to evaluate the adapted version among children in Guam.MethodsAdaptations to the WillTry tool included both novel fruits and vegetables unique to Guam and common ones. Children aged 3 to 11 years who attended 2 community-based summer day camps in 2013 were shown images matching 14 food questions in an initial interview and in a second interview conducted 3 to 72 hours later. Responses were "no," "maybe," or "yes" and were coded as 1, 2, or 3, respectively. A higher score indicated more willingness to try fruits and vegetables. Factor analyses determined components of willingness. Psychometric properties and reliability were analyzed.ResultsSixty-five children completed the first interview, and 64 completed the second. Factor analyses revealed 3 components (scales): 1) local novel (guava, breadfruit, eggplant, sweet sop, star apple, taro leaves), 2) local common (carrot, papaya, long beans, salad greens), and 3) imported (apple, canned peaches, canned corn). All but the imported scale had sufficient internal consistency (Cronbach's alpha > 0.69). Each scale had substantial reliability (ICC > 0.76). We found no significant differences by age, sex, or type of camp for any scale. Mean scores were 2.1 (local novel), 2.4 (local common), and 2.7 (imported), and all were significantly different.ConclusionThe adapted WillTry was culturally relevant and had psychometric properties similar to those of the original. An unexpected finding was the tool's potential for documenting the nutrition transition.
