Abstract Due to its simplicity, Check-all-that-apply (CATA) is a promising method for consumer studies with children to generate sensory and other descriptions of samples, and to find their drivers of liking. This paper explores how children’s approach to the CATA test influences the outcome, based on two case studies that illustrate suitable setups for CATA tests with children of the age group 6–9. The children's approach to the CATA task was described with ticking style indicators based on which three ticking style groups were defined. One group ticked only a few attributes probably due to cognitive limitations, e.g. lack of reading skills, limited vocabulary or ability to focus on the task. The second group gradually increased their number of ticked attributes per sample over the test, while the third subgroup ticked a steady number of attributes throughout the test. The two latter groups are likely to represent different test strategies: one using the CATA list relatively to the sample space, and one using the CATA list as in a more absolute way. Analysis regarding data validity assessed by the detection of pre-defined Design of Experiment (DoE) sample differences and the alignment to a trained panel using Quantitative Descriptive Analysis (QDA) revealed that ticking style played a crucial role. This study shows the importance of analysing “ticking style” as a validation strategy for CATA tests run with children and as a tool to gain insights into underlying test strategies.

儿童如何进行 CATA 测试会影响结果。从两个 6-9 岁儿童案例研究中对滴答风格的见解

摘要 由于其简单性,Check-all-that-apply (CATA) 是一种很有前途的方法,用于对儿童进行消费者研究,以生成样品的感官和其他描述,并找到他们的喜好驱动因素。本文基于两个案例研究,探讨了儿童对 CATA 测试的方法如何影响结果,这些案例研究说明了适用于 6-9 岁儿童的 CATA 测试的设置。孩子们在 CATA 任务中的方法是用滴答风格指标描述的,基于这些指标定义了三个滴答风格组。一组可能由于认知限制而只勾选了几个属性,例如缺乏阅读技能、词汇量有限或专注于任务的能力。第二组在测试中逐渐增加每个样本的勾选属性数量,而第三个子组在整个测试中勾选了稳定数量的属性。后两组可能代表不同的测试策略:一组使用相对于样本空间的 CATA 列表,另一组以更绝对的方式使用 CATA 列表。通过检测预定义的实验设计 (DoE) 样本差异和使用定量描述分析 (QDA) 与训练有素的面板对齐来评估数据有效性的分析表明,滴答风格起着至关重要的作用。这项研究表明,分析“滴答风格”作为对儿童进行的 CATA 测试的验证策略以及作为深入了解潜在测试策略的工具的重要性。以及以更绝对的方式使用 CATA 列表。通过检测预定义的实验设计 (DoE) 样本差异和使用定量描述分析 (QDA) 与训练有素的面板对齐来评估数据有效性的分析表明,滴答风格起着至关重要的作用。这项研究表明,分析“滴答风格”作为对儿童进行的 CATA 测试的验证策略以及作为深入了解潜在测试策略的工具的重要性。以及以更绝对的方式使用 CATA 列表。通过检测预定义的实验设计 (DoE) 样本差异和使用定量描述分析 (QDA) 与训练有素的面板对齐来评估数据有效性的分析表明,滴答风格起着至关重要的作用。这项研究表明,分析“滴答风格”作为对儿童进行的 CATA 测试的验证策略以及作为深入了解潜在测试策略的工具的重要性。
