Summary
Evening-type individuals tend to be more impulsive than morning-types. This finding suggests potential circadian interventions for managing impulsivity, regardless of gender.
Area of Science:
- Chronobiology
- Psychology
- Personality Science
Background:
- Morningness-eveningness describes individual circadian preferences.
- Impulsivity is a key trait in personality disorders.
- Sensation seeking and venturesomeness are related constructs.
Purpose of the Study:
- To investigate the relationship between morningness-eveningness and impulsivity.
- To explore the role of gender and age in this relationship.
- To examine venturesomeness as a potential covariate.
Main Methods:
- A cross-sectional study using self-administered questionnaires.
- Participants included 194 males and 358 female students.
- Data analyzed using a four-way analysis of covariance.
Main Results:
- Higher impulsivity was significantly associated with greater eveningness.
- Age and gender also significantly influenced morningness-eveningness.
- Venturesomeness did not show a significant effect on morningness-eveningness.
Conclusions:
- Impulsivity is linked to evening-type circadian preference.
- Findings suggest potential physiopathological links to impulsivity.
- Circadian interventions like bright light therapy may offer treatment avenues for impulsivity.
