CATA questions (check-all-that-apply) are popular for sensory product characterisation tasks with consumers. Lingering uncertainty over the meaning of term citation frequency was addressed in the present research, which directly compared CATA questions with intensity and applicability ratings obtained on 10 cm unstructured line scales. In three studies (n ~ 210 consumers per study), evidence fitting with expectations based on the extant literature was obtained to confirm that citation frequency reflects intensity. The two response types were strongly linearly related, meaning that it is possible to infer significant differences between samples for a given CATA term as representing differences in perceived intensity. This finding emphasises how, despite the simplicity of the CATA task and the fact that individual responses are not measures of intensity, the average citation frequencies do reflect perceived intensity. Therefore, across a group of consumers, there is no information loss relative to rating scales. A systematic difference between citation frequencies and intensity ratings was attenuation of scale use in the latter, which was between 15 and 80 on a 0 to 100 scale. Attenuation was less pronounced in CATA responses which spanned approx. 5 to 85%. In the second part of the research, which included six studies (n ~ 135 to 205 consumers per study) CATA questions were compared with applicability ratings obtained on 10 cm unstructured line scales. The results were highly similar to the comparison between CATA questions and intensity scales and further confirmed that average CATA term citation frequency can be interpreted as representing (but not directly measuring) consumers’ intensity perceptions. The attenuation in scale range was again observed. Collectively, the results contribute further support for the popularity of CATA questions for sensory characterization by consumers in product testing.
