Resum
The application of check-all-that-apply (CATA) questions for sensory product characterisation is gaining
acceptance and popularity. This question format has been reported to be a quick and reliable means of
gathering sensory profiles from consumers, concurrently with hedonic assessment. However, a limitation
of CATA questions is that they do not encourage deep processing by respondents. Forced-choice questions,
where respondents answer ‘‘yes’’ or ‘‘no’’ for each term, may encourage systematic processing
and be useful when consumers undertake sensory profiling tasks. This research compared sensory profiles
elicited by consumers using CATA questions or forced-choice Yes/No questions and contribute to
ongoing investigations of CATA questions and related question formats with a view to developing guidelines
for best practise. Across seven consumer studies with 600+ consumers and multiple product categories,
consistent evidence was obtained that forced-choice Yes/No questions are associated with higher
term citation frequencies. However, this did not consistently translate into greater product discrimination.
Conclusions regarding similarities and differences amongst samples and the stability of sample
and term configurations were generally independent of question format (i.e., whether the sensory data
were elicited by CATA or forced-choice Yes/No questions). Overall, the comparison of CATA and forcedchoice
Yes/No questions for sensory characterisation suggested parity of the two question formats. This
extended to consumers’ perceived difficulty and tediousness for completing the test. Regardless of question
format, consumers, on average, perceived the tests as easy and not tedious.
