SUMMARY:

Caffeine (1,3,7-trimethylxanthine), present in some beverages and foods, is one of the most consumed substances in the world and has been widely studied and used for its effectiveness as an ergogenic resource and inserted in some, as it has a mechanism of action both accelerate absorption and prolong the analgesic effect of drugs such as paracetamol. Studies have also shown that caffeine increases alertness, motivation, mood, attention and memory. This xanthine is an easily accessible substance, as it is present in several foods and/or products, however, its effects depend on the daily amount consumed. Due to this diversity and its possible interactions with physical performance and human health, it is relevant to assess the caffeine content consumed, however, care must be taken with the evaluation method used, as imprecise measurements do not show the real value of your intake. Caffeine Consumption Questionnaires (QCCs), when validated and tested, can be a good alternative to quantify the consumption of this substance. However, a QCC with validity and reproducibility tested with complete methodology has not yet been identified in the literature. In order to facilitate the assessment of consumption of this substance, we developed and evaluated the validity and reproducibility of a QCC. Thus, the aim of this study was to test the validity and reproducibility of a QCC. The QCC was designed to assess caffeine consumption for the last 2 months. Data collection took place at 3 different times, contact with the volunteers took place online and by telephone, 3 24-hour Recollections (REC24H) and 2 QCCs were applied. The sample consisted of 100 adults, where 76% were female and mean age was 33.52 ± 6.65. The value of the correlation coefficient was 0.72 in the first moment between the elaborated QCC and the average of the 3 REC24H, As well as, there was a high correlation coefficient, 0.91, between the caffeine value from the QCC1 and the QCC2 . The results of the validity and reproducibility analyzes of the instrument developed in this study show that the QCC has good validity, including in the analysis of the QCC in its two application moments, and also presents good reproducibility.
