RT Journal Article T1 Circadian typology is related to emotion regulation, metacognitive beliefs and assertiveness in healthy adults A1 Antúnez-Vílchez, Juan Manuel K1 Ritmos circadianos AB This study explores the relationship between circadian typology and three key psychological constructs: emotion regulation, metacognitions, and assertiveness, considering possible sex differences. A total of 2,283 participants (833 women), aged 18-60, completed questionnaires assessing morningness-eveningness, emotion regulation, metacognitions, and assertiveness.The findings revealed significant effects of circadian typology on several psychological factors, including cognitive reappraisal, metacognitions, negative beliefs about uncontrollability and danger, cognitive confidence, cognitive self-consciousness, and assertiveness. Morning-type individuals scored lower on maladaptive metacognitive beliefs and higher on cognitive reappraisal and assertiveness compared to evening-type participants, with neither-type falling in between.The study suggests that evening-type individuals are more prone to maladaptive thinking patterns and may struggle with reappraisal of emotional situations and assertiveness. These findings highlight evening-type as a potential risk factor for psychological issues, while morning-type may serve as a protective factor. Further longitudinal research is needed to confirm these associations.
