ABSTRACT
It is still not clear how chronotype influences caffeine consumption (CC) and caffeine use disorder (CUD). The aim of the study was to investigate the relationship between chronotype, CC, CUD, and wellbeing. Participants of an online survey in Hungary (N = 2259) answered the CUD Questionnaire, Morningness-Eveningness Questionnaire and the WHO-5 Well-Being Index. Morningness positively associated with tea consumption, and negatively with cola and energy drink consumption. Severe CUD was more common among evening-type participants. Two significant mediations were found in the path model MorningnessâTea consumptionâWellbeing and EveningnessâEnergy drink consumptionâCUD. It is concluded that CUD like other substance use disorders is associated with eveningness. The results indicate that the carrier beverages of the chemical compound of caffeine should be examined separately. Energy drink use can be accompanied by more unfavorable consequences, especially for evening-types, while tea consumption, which was associated with morningness, had more favorable consequences, like higher wellbeing.
